Study links PM2.5 pollution to heart damage

May 26, 2017

Research presented at the annual CMR (cardiovascular magnetic resonance) imaging conference of the European Association of Cardiovascular Imaging (EACVI) links PM2.5 pollution to heart damage. Among the sources of urban PM2.5 are diesel and gasoline direct injection (GDI) engines (earlier post).

There is strong evidence that particulate matter (PM) from road vehicles is associated with increased risk of heart attack, heart failure, and death, said lead author Dr. Nay Aung, a cardiologist and Wellcome Trust research fellow, William Harvey Research Institute, Queen Mary University of London, UK. “This appears to be driven by an inflammatory response—inhalation of fine particulate matter (PM2.5) causes localized inflammation of the lungs followed by a more systemic inflammation affecting the whole body.

Swiss team concludes that particulate filters should be mandatory for GDI engines

May 24, 2017

Based on a three-year study of toxic and environmentally relevant pollutants from gasoline direct injection (GDI) engines, Swiss researchers have concluded that some GDI engines emit just as many soot particles as unfiltered diesel cars did in the past. Further, the GDI particles carry numerous carcinogenic substances. Based on this current data, they recommend that particulate filters be mandatory for GDI engines.

In the spring 2014, the GasOMeP project (Gasoline Vehicle Emission Control for Organic, Metallic and Particulate Non-Legislative Pollutants) got underway. The Paul Scherrer Institute (PSI), Bern University of Applied Sciences, the University of Applied Sciences and Arts Northwestern Switzerland, several industrial partners and Empa were all involved. The project was funded by the ETH Domain’s Competence Center for Energy and Mobility (CCEM) and coordinated by Empa chemist Norbert Heeb, who has made a name for himself in the last 25 years by analyzing diesel emissions and studying filter systems.

US sues Fiat Chrysler over diesel emissions

May 23, 2017

The Environmental and Natural Resources Division of the US Department of Justice (DOJ-ENRD) has filed a lawsuit against Fiat Chrysler for using software defeat devices in nearly 104,000 Ram 1500 and Jeep Grand Cherokee vehicles (Model Years 2014-2016) with 3.0-liter diesel engines.

The US Environmental Protection Agency (EPA) had issued a notice of violation (NOV) to FCA over the alleged violations of the Clean Air Act in January 2017. (Earlier post.) The undisclosed engine management software results in increased NOx emissions from the vehicles, EPA said. Since then, FCA US has been working with the EPA and the California Air Resources Board (CARB), including extensive testing of the vehicles, to clarify issues related to the emissions control technology.

2018 Volkswagen Tiguan powered by 2.0L EA888 Gen3B engine

The all-new 2018 Volkswagen Tiguan arrives in US dealerships this summer powered by the most advanced version yet of Volkswagen’s EA888 four-cylinder engine, the Gen3B. The updated version of the four-cylinder, turbocharged and direct-injection engine uses a modified Miller cycle to offer an improved combination of power, efficiency and responsiveness. Audi engineers described the development of the Gen3B at the Vienna Motor Symposium in 2015. (Earlier post.) The Audi version of the EA888 Gen3B made its debut in the new A4.

First introduced in the 2009 CC, the EA888 continued Volkswagen’s move toward smaller, turbocharged engines that offer the fuel economy benefits of downsizing with the power of a larger-displacement unit. Though EPA estimates are not yet available, compared with the 1.8-liter EA888 Gen 3 engine that is fitted in the current Passat, Jetta, Beetle, and Golf family models, the new 2.0-liter EA888 Generation 3B is expected to offer improved fuel efficiency along with a 20% boost in maximum torque to 221 lb-ft (300 N·m).

Researchers show mechanism by which diesel exhaust particles trigger respiratory “flare-ups”

Researchers at Imperial College London, working with colleagues from King’s College London and University of British Columbia, have demonstrated a mechanism by which diesel exhaust particles directly affect the lungs to initiate symptoms such as a tightening of the airways and cough. These triggered respiratory reflexes can potentially worsen underlying conditions, such as asthma.

Previous research has shown a strong association between urban air pollution and respiratory symptoms such as coughing, wheezing and shortness of breath, but the underlying mechanism has been unclear. In the study, published as an open-access paper in the Journal of Allergy and Clinical Immunology, the team showed that polycyclic aromatic hydrocarbons (PAHs) in the exhaust particles directly stimulate nerves in the lungs, causing a reflex response in the airways.

DOE: gasoline direct injection engine technology showing very rapid adoption; 48.5% market share after 9 years

Gasoline direct injection (GDI) technology has seen very rapid adoption in the US since its first significant use, according to data gathered by the US Department of Energy’s (DOE) Oak Ridge National Laboratory (ORNL). Only nine years after its first significant use in the market, GDI penetration has climbed to 48.5% market share. (First significant use generally represents a production threshold of about 1%.)

Many auto manufacturers have used the combined benefits of GDI and turbocharging for increasing power output from downsized engines. This is evident in the rapid rise of turbo-charged engines in over the past five years, after 11 prior years of desultory growth.

Study finds fleet switch from PFI to GDI engines will result in net reduction in global warming

May 12, 2017

A new study quantifying emissions from a fleet of gasoline direct injection (GDI) engines and port fuel injection (PFI) engines finds that the measured decrease in CO2 emissions from GDIs is much greater than the potential climate forcing associated with higher black carbon emissions from GDI engines. Thus, the researchers concluded, switching from PFI to GDI vehicles will likely lead to a reduction in net global warming.

The study, by a team of researchers from Carnegie Mellon University, University of Georgia, Aerodyne Research, California Air Resources Board (ARB), Ohio State University, UC Berkeley, and UC San Diego is published in the ACS journal Environmental Science & Technology.

IAV develops new close-coupled diesel exhaust gas aftertreatment system for improved emissions reduction

May 08, 2017

IAV has developed a particularly closed-coupled diesel exhaust gas aftertreatment (EAT) system. The design allows the diesel oxidation catalyst (DOC) and particular filter/selective catalytic reduction (DPF/SCR) units to reach optimum working temperature more quickly which, even when driving in the low-load range, significantly cuts emissions.

Under the EU6 standard, diesel engines are still allowed to emit up to 80 mg NOx/km milligrams of nitrogen oxides per kilometer—not only under the legal framework in the cycle but also in respect of increasingly tighter RDE requirements. Future diesel powertrains will need to be capable of meeting limit values that are even tighter than EU6.

Clemson research developing integrated modeling and control systems to reduce particulates from GDI engines

April 21, 2017

Simona Onori, an assistant professor at Clemson University, has received a $500,000 Faculty Early Career Development Program (CAREER) award from the National Science Foundation to advance her work to develop integrated modeling and control for aftertreatment systems to reduce fine-particle emissions from gasoline direct injection (GDI) engines.

GDI engines now account for about 60% of the US market, and their use worldwide is forecast to grow. GDI engines have better fuel economy and lower carbon-dioxide emissions than more conventional port fuel injection engines; however, the technology results in higher fine-particle emissions. The research Onori and her team are doing focuses on gasoline particulate filters (GPF). While the dynamics of diesel engine particulate filters (DPF) are well understood, particulates produced in GDI engines have substantially different characteristics.

ICCT: incremental technology can cut vehicle CO2 by half and increase fuel economy >60% through 2030 with ~5% increase in price

March 22, 2017

With the EPA re-opening its Mid-Term Review of GHG standards for 2022-2025 for light-duty vehicles (earlier post), and with NHTSA yet to weigh in on its Mid-Term evaluation of fuel economy standards for the same period, a team from the International Council on Clean Transportation (ICCT) has published a report analyzing emerging vehicle efficiency technologies; their ability to achieve lower emission levels; and their costs in the 2025–2030 timeframe.

Starting from a baseline 26 mpg (9.04 l/100 km) in 2016, the The ICCT team assessed increased consumer label fuel economy (as opposed to the regulatory test fuel economy) to 35 mpg (6.71 l/100 km) in 2025 and to 42–46 mpg (5.6-5.11 l/100 km) (under three scenarios) by 2030. These fuel economy levels are achieved based on a sustained 4%–6% annual reduction of fuel use per mile with incremental technology additions that do not compromise vehicle size or utility at an incremental cost of $800–$1,300 from 2025 to 2030. The resulting trajectory would reduce CO2 emissions by half and increase fuel economy by more than 60% from 2016 through 2030. Based on a detailed analysis of the efficiency technologies used to achieve these lower CO2 emission levels, the ICCT study concludes that vehicle prices would increase by about 5% by 2030.

Study finds black carbon pollution directly affects bacteria; altering effectiveness of antibiotics, increasing the potential for infection

March 03, 2017

Researchers from the University of Leicester (UK) have shown for the first time that black carbon, a major component of air pollution, directly affects bacteria that cause respiratory infections—Streptococcus pneumoniae and Staphylococcus aureus—thereby increasing the potential for infection and changing the effectiveness of antibiotic treatment. S. pneumoniae is the leading bacterial cause of pneumonia, and S. aureus is a significant cause of respiratory and skin and tissue disease.

The interdisciplinary study, published in the journal Environmental Microbiology, has important implications for the treatment of infectious diseases, which are known to be increased in areas with high levels of air pollution. The study looked into how air pollution—specifically black carbon—affects the bacteria living in the respiratory tract—the nose, throat and lungs. Black carbon, a major component of particulate matter, is produced through the burning of fossil fuels such as diesel, biofuels, and biomass.

New KOSi method for ultra-deep desulfurization of fuels to ~ 2ppm S

February 28, 2017

Scientists led by a team at Caltech and BP, and in collaboration with researchers at UCLA, ETH Zürich, and China’s Nanjing University, have developed a new method for potentially removing nearly all sulfur compounds (down to ~2 ppm) from gas and diesel fuel. The method uses Earth-abundant materials (potassium (K), oxygen (O), and silicon (Si)—hence its name, “KOSi”) and operates under mild conditions.

Sulfur compounds in fuels such as gasoline and diesel create air pollution when the fuel is burned. To address that challenge, large-scale hydrodesulfurization (HDS) at refineries remove the majority of sulfur from fuel down to a government-mandated level. The new technique, however, has the potential to reduce sulfur down to a fraction of that amount, which would further reduce air pollution and extend the lifetime of vehicles’ catalytic converters, which control tailpipe emissions. A paper on their work is published in the journal Nature Energy.

In the wake of a report by the German television station ZDF identifying widespread aftermarket manipulation of NOx emissions control technologies on trucks, the European Automobile Manufacturers’ Association (ACEA) is calling for government action to preclude such manipulation.

The ZDF report, based on research ZDF commissioned at the University of Heidelberg, found that some 20% of trucks operating in eastern Europe have effectively circumvented NOx reduction technology, causing around 14,000 tonnes more NOx to be emitted per year than would be the case if all trucks that say they use AdBlue were doing so. The additional 14,000 tonnes of NOx would make it twice the size of the Volkswagen “Dieselgate” scandal of 2015, noted environmental NGO T&E.

Study links PM2.5 pollution with millions of preterm births globally

February 19, 2017

A new study, led by a team from The Stockholm Environment Institute (SEI) at the University of York, has found that in 2010, about 2.7 million preterm births globally—or 18% of all pre-term births—were associated with outdoor exposure to fine particulate matter (PM2.5).The open-access study is published in the journal Environment International.

There are many known risk factors for preterm birth—from the mother’s age, to illness, to poverty and other social factors. Recent research has suggested that exposure to air pollution could also be a risk factor. The researchers combined national, population-weighted, annual average ambient PM2.5 concentration, preterm birth rate and number of livebirths to calculate the number of PM2.5-associated preterm births in 2010 for 183 countries.

DLR, AEB developing new injection heads enabling use of ethanol as rocket fuel

February 16, 2017

The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and the Brazilian aerospace agency Agência Espacial Brasileira (AEB) have successfully completed the first burn tests for two newly designed injection heads enabling the development of a new rocket that is fueled with oxygen and alcohol.

The final injection head will eventually be the core of the new L75 liquid propellant rocket engine (LPRE), intended to propel a Brazilian small launch vehicle in the future. The engine delivers 75 kN thrust, fueled with liquid oxygen and ethanol, with a burn time of up to 400 seconds. (For comparison, Space X’s Falcon 9’s second stage—used to place large payloads into orbit—is powered by a single Merlin engine with 934 kN thrust. Falcon 9’s first stage delivers 7,607 kN at sea level.) The burn test series for the upper stage engine was completed within the framework of a German-Brazilian partnership established in 2011.

Study suggests GTL-naphtha-gasoline-ethanol blends can function as well as gasoline with lower emissions

February 05, 2017

Results of a study by a team from the University of Birmingham (UK) and Shell Global Solutions suggest that blends of gasoline with gas-to-liquids (GTL) naphtha can perform comparable combustion and full power output to conventional gasoline, with less than 2% difference in normalized ISFC (indicated specific fuel consumption) and gaseous emissions similar to, if not lower than that of conventional gasoline. A paper on their study is published in the journal Fuel.

The GTL Fischer-Tropsch process produces GTL diesel (the cleaner combustion and emissions qualities of which have been well studied), GTL naphtha, GTL kerosene, GTL normal Paraffin and GTL base oils. GTL naphtha mainly contains C4 to C11 hydrocarbons with a high proportions of straight chain paraffins. Although it has a consistent quality and near-zero sulfur and heavy metals, GTL naphtha has a low octane rating, making it unsuitable for blending in gasoline. (GTL naphtha currently is used as an alternative high-quality feedstock for plastics.) However, that low octane rating can be addressed by using ethanol as an octane booster.

Study: splash blended ethanol fuels with higher ethanol percentage enable higher thermal efficiency in SI engine

February 03, 2017

A team from the University of Birmingham (UK) and Shell Global Solutions has investigated the effect of RON, octane sensitivity and charge cooling in splash-blended ethanol fuels with different volume percentages of ethanol on a single-cylinder direct-injection spark ignition (DISI) research engine.

In a paper published in the journal Fuel, the researchers report that at the knock-limited engine loads, splash-blended ethanol fuels with a higher ethanol percentage enabled higher engine thermal efficiency through allowing more advanced combustion phasing and less fuel enrichment for limiting the exhaust gas temperature under the upper limit of 850 °C, which was due to the synergic effects of higher RON and octane sensitivity, as well as better charge cooling.

New CE-CERT report finds Cummins Wesport ISL G near-zero gas engine performs with lower NOx than EPA certification standard over range of cycles

February 02, 2017

A report released by the University of California Riverside’s College of Engineering-Center for Environmental Research and Technology (CE-CERT), found that the new 8.9L Cummins Westport ISL G near-zero (NZ) natural gas engine (earlier post) meets and exceeds the certification standards during a full range of duty cycles. This finding is in stark contrast to previously released CE-CERT data and a recently released report by the California Air Resources Board that found heavy-duty diesel trucks emitted higher levels of NOx than their certification standards in the same duty cycles.

With the near-zero emission factors demonstrated for natural gas vehicles, it is expected that these vehicles could play an important role in providing much needed emissions reductions required for the South Coast Air Basin and California to reach federal air quality attainment standards.

Saudi Aramco R&D proposes SuperButol as new low-cost high-octane blend component

January 27, 2017

A team from Saudi Aramco Research and Development Center has developed a novel low-cost, high-octane gasoline blend component it calls SuperButol. SuperButol is made from low-value mixed butenes using a new process the team has named Butenes to Butanol (BTB); it has slightly lower blending RON compared to MTBE but has lower blending vapor pressure and higher energy content compared to ethanol.

It also has an insignificant effect on key gasoline specifications, including potential and actual gum; oxidation stability; intake valve deposits; port fuel injector fouling; haze formation; and water extractability performance. The team suggests that SuperButol is thus a viable and affordable gasoline component, which can help to meet future demands for high-octane gasoline. In addition, the process helps to optimize refinery operations by valorizing low-value products. The team describes SuperButol in a paper in the journal Fuel.

POSTECH, Hyundai team develops new more thermally robust catalyst for NOx reduction with diesel engines

January 23, 2017

A team from Pohang University of Science and Technology (POSTECH) in S. Korea, with colleagues from Hyundai Motors’s R&D group and the University of St. Andrews in the UK has developed a new, more thermally robust catalyst for NOx aftertreatment systems for diesel engines. A paper on their work is published in the journal Angewandte Chemie International Edition.

The catalyst—divalent copper ions fully exchanged into high-silica LTA zeolites(Cu-LTA)—demonstrated excellent maintenance of activity for NOx reduction with NH3 under vehicle-simulated conditions even after hydrothermal aging at 900 °C, a critical temperature that the current commercial Cu-SSZ-13 catalyst cannot overcome owing to thermal deactivation.

CARB releases Midterm Review of ZEV regulation, LEV III GHG and PM standards; calls for post-2025 standards

January 19, 2017

When the California Air Resources Board (ARB) adopted the Advanced Clean Cars (ACC) program in 2012 (earlier post), the agency committed to conduct a comprehensive midterm review of three elements of the program: the zero-emission vehicle (ZEV) regulation; the 1 mg/mi particulate matter (PM) standard; and the light-duty vehicle greenhouse gas standards for 2022 and later model years. ARB has now released the Midterm Review of Advanced Clean Cars Program—an extensive evaluation of the California passenger vehicle market and technology.

The Review finds that the greenhouse gas (GHG) emission standards currently in place for model years 2022-2025 are readily feasible at or below the costs estimated back in 2012. The report also finds that ZEV technology has seen significant development that, in many cases, is beyond what was envisioned just four years ago. The report indicates that existing programs in California will add at least 1 million zero-emission vehicles on its roads and highways by 2025.

DOE Co-Optima initiative publishes report reviewing first 12 months; progress on fuels and engines

January 16, 2017

The US Department of Energy’s (DOE’s) Co-Optima initiative—a broad, joint effort to co-optimize the development of efficient engines and low greenhouse-gas fuels for on-road vehicles with the goal of reducing petroleum consumption by 30% by 2030 beyond what is already targeted (earlier post)—has published a year-in-review report for FY 2016—the initiative’s first 12 months.

Co-Optima’s premise is that current fuels constrain engine design—and thus engine efficiency. The researchers suggest that there are engine architectures that can provide higher thermodynamic efficiencies than available from modern internal combustion engines; however, new fuels are required to maximize efficiency and operability across a wide speed/load range. The report details the technical progress in a selection of projects across the initiative’s two main thrusts: spark ignition (SI) and advanced compression ignition (ACI).

Achates Power building 2.7L opposed-piston light-duty engine; exceeding CAFE 2025, Tier 3 targets at lower cost

January 13, 2017

Stemming from a major project partially funded with a $9-million grant from the Advanced Research Projects Agency - Energy (ARPA-E) to develop an opposed-piston two-stroke gasoline compression ignition engine (OPGCI) (earlier post), Achates Power announced it is developing a 2.7-liter, 3-cylinder (i.e., six-piston) light-duty version of its opposed piston engine (OPE) in both diesel- and gasoline-fueled versions. Achates will demonstrate the engine in 2018 in a driveable light-duty truck.

The 2.7-liter compression-ignition OPE will will be 30-50% more fuel efficient than comparable diesel and gasoline direct injection engines, reduce emissions and cost less than alternative technologies under development for meeting 2025 CAFE fuel economy and Tier 3 emission targets.

ICCT: New RDE regulations not enough to control diesel car NOx fully; additional actions required

Real-world NOx emissions from new diesel cars could still exceed the Euro 6 emission limit of 80 mg/km by a factor of three or more, even after the new Real-Driving Emissions (RDE) regulation takes effect, according to a new white paper released by the International Council on Clean Transportation (ICCT). However, taking specific actions beyond those mandated in the regulation—such as introducing spot checks for randomly selected vehicles and expanding the range of driving conditions covered by RDE testing—could reduce new diesel car NOx emissions to 96 mg/km—just 1.2 times the Euro 6 limit—by 2022.

For the study, the team analyzed an extensive set of diesel car emissions data using modeling of the boundary conditions of the RDE regulation. The researchers also examined the impact of ICCT’s proposed modifications.

Oberon Fuels, Mack Trucks, and New York City Department of Sanitation begin first customer demonstration of a DME-powered Mack Truck

January 12, 2017

Oberon Fuels, a producer of clean-burning Dimethyl Ether (DME) transportation fuel (earlier post), announced the first customer demonstration of a DME-powered Mack truck, a Mack Pinnacle. Oberon and Mack are working with the NYC Department of Sanitation (DSNY) to run the vehicle at the Fresh Kills Landfill and evaluate performance and overall drivability. The test is the first step in the city’s evaluation of both DME trucks and DME fuel as a potential long-term strategy to help reduce greenhouse gas emissions by 80% by 2050 and to achieve the city’s goal of sending zero waste to landfill by 2030.

The goal of the demonstration is to gather data on the use of DME fuel and vehicles in urban, heavy-load fleets. At scale, such a program could convert hundreds of thousands of tons of organic waste into clean fuel, reducing emissions, waste, and costs for cities while improving overall air quality and creating jobs.

EPA and CARB approve emissions modification for Gen 3 VW 2.0 liter diesel vehicles

January 06, 2017

The US Environmental Protection Agency (EPA) and California Air Resources Board (CARB) approveda remedy proposed by Volkswagen that will reduce the excess NOx emissions from the Generation 3 (MY 2015) diesel 2.0 liter vehicles. With the approval, VW can offer vehicle owners the choice to keep and fix their car, or to have it bought back.

This modification will reduce excess emissions from the affected vehicles by 80-90%. The test data and technical information VW submitted to EPA and CARB demonstrated that the emissions modification being approved will not affect vehicle fuel economy, reliability, or durability. EPA and CARB confirmed those conclusions through independent testing and analysis at their own laboratories.

ICCT: real-world NOx from Euro 6 diesel passenger cars more than 2x Euro VI diesel trucks

In Europe, the average amount of NOx present in exhaust emissions from modern diesel passenger cars under real-world conditions is more than double the levels from modern trucks and buses, according to a new briefing paper released by the independent research organization International Council on Clean Transportation (ICCT).

The ICCT paper shows data for 24 Euro VI buses and trucks, some tested on a chassis dynamometer by the Technical Research Centre of Finland (VTT), and others tested on-road using portable emissions testing equipment by the German type-approval agency KBA. On average, NOx emissions of the heavy-duty vehicles tested were approximately 210 mg/km. Currently, NOx emissions of Euro 6 diesel passenger cars under real-world driving conditions are approximately 500 mg/km, as determined by testing carried out by KBA and other European type-approval agencies. In addition, the average conformity factor—the ratio of the test result to the regulatory limit—for the heavy-duty engines was less than 1, meaning that on-road emissions stayed below the Euro VI engine type-approval test limits.

Honeywell Transportation Systems Forecast: turbocharged vehicles to account for 48% of annual global sales by 2021; electric boosting emerges

December 09, 2016

Honeywell’s Transportation Systems Forecast projects that turbocharged vehicles will acount for 48% of annual global sales by 2021, up 9 percentage points from 2016. This annual sales estimate, combining both passenger and commercial vehicles, would add more than 232 million turbocharged vehicles globally between 2017 and 2021—an increase of 35% from today.

This year’s forecast recognizes an industry trend for slightly bigger engine sizes in Europe and China as automakers adapt powertrain strategies to tackle updated emissions regulations developed for real-world driving conditions. In these regions, a typical powertrain is a three- or four-cylinder engine with a displacement size between 1.2 liters and 1.7 liters. By rightsizing engines with available technologies, automakers are able to continue applying the benefits of smaller turbocharged engines while fine-tuning powertrain systems to further optimize fuel economy, emissions and performance.

New ORNL hardware-in-the-loop capability to integrate advanced combustion, new fuels, and electrification pathways

December 02, 2016

A multi-disciplinary team of researchers at Oak Ridge National Laboratory (ORNL) has developed a new testing capability which integrates a driver model, full vehicle model, and hardware to explore the synergies of advanced combustion, new fuels, and emerging hybrid vehicle architectures over real-world drive cycles. This new facility is focused on low temperature combustion engines but builds upon the powertrain-in-the-loop expertise established with the Vehicle Systems Integration Laboratory (VSI) at ORNL.

The transient advanced combustion laboratory is initially supporting research on the potential of low temperature combustion modes with new fuel and vehicle technologies. The hardware-in-the-loop setup includes a transient dynamometer cell (AVL 300 kW AC) with a low-temperature combustion (LTC) multi-cylinder engine instrumented for combustion and emissions analysis. The light-duty diesel engine used in these experiments (earlier post) was modified for dual-fuel use for port fuel injection of low-reactivity fuel (i.e. gasoline, ethanol etc.) and a high-reactivity fuel (i.e. diesel, biodiesel etc.).

ICCT: 2025 target average of 70 g/km CO2 for new cars in EU feasible and economical; more so with electric drive

A 2025 CO2 target of an average 70 g/km for new cars in the EU could be met with very little electrification and with an average payback period of less than 4 years, according to a new study by the International Council on Clean Transportation (ICCT). However, transitioning soon to electric drive could lower manufacturers’ compliance costs by as much as €500 (US$532) per vehicle in 2025.

Under current European Union regulations, average new car CO2 emissions must decrease from the present 120 grams per kilometer (g/km) to 95 g/km by 2021. Although no further reductions are presently mandated, new targets for 2025 and 2030 are under discussion in Brussels. In 2013 the European Parliament recommended an “indicative range” of 68–78 g/km for 2025, while holding out the possibility that even lower targets should be considered if justified.

Argonne study on optimizing gasoline compression ignition at idle and low loads

November 09, 2016

Gasoline compression ignition—i.e., igniting gasoline purely by compression, as with a diesel, rather by using a spark—is a promising, high-efficiency, low-temperature combustion mode that offers low engine-out NOx and soot. (Earlier post.) GCI, however, is challenged by stable idle- to low-load operation (i.e., 0-2 bar BMEP) because it is challenging to ignite the low-reactivity gasoline purely through compression.

One way to address that challenge is through optimizing the injection system and injection strategy to ensure that the air-fuel mixture maintains a high level of reactivity. A team from Argonne National Laboratory now reports in a paper published in the International Journal of Engine Research on the effects of injector nozzle inclusion angle, injection pressure, boost, and swirl ratio on gasoline compression ignition combustion.

Ricardo’s “deep” Miller cycle concept: Magma

November 01, 2016

In its new report on downsized and boosted gasoline engine technologies (earlier post) the ICCT highlighted Ricardo’s work on an “extreme” Miller cycle concept with high (13:1) compression ratio (CR) and central direct injection in a downsized boosted engine.

The basic architecture of “Magma” concept is a boosted four-stroke gasoline engine with four valves per cylinder. The Magma concept architecture closes the inlet valve early to reduce pumping losses. A mechanical supercharger and fixed-geometry turbocharger fill cylinders effectively. A long exhaust stroke then extracts maximum efficiency.
