Daimler Buses to offer electrohydraulic power steering to reduce fuel consumption
October 19, 2016
Daimler Buses will offer electrohydraulic power steering (EHPS) to reduce fuel consumption in coming bus models. The fully integrated system replaces the conventional power steering pumps used currently in all buses with a gross weight of more than 7.5 t.
Conventional hydraulic power steering (HPS) is driven directly by the internal combustion engine via belts or gear trains with a fixed gear ratio which results in a pump speed that is directly proportional to the engine speed. To provide sufficient power for the steering in every situation, the pump must be able to deliver the full volumetric flow rate even when the engine speed is low—meaning that it is over-dimensioned for most operating situations. For this reason, higher engine speeds require a restriction of the volumetric flow rate by means of a bypass, which, however, entails unnecessary losses.

Final testing confirms ADEPT 48V diesel hybrid reduces fuel consumption 10-12% at low incremental cost
September 13, 2016
The three-year ADEPT (advanced diesel-electric powertrain) project (earlier post) in the UK set the target of developing and validating a range of advanced mild hybrid technologies with 48V “intelligent electrification” utilizing an advanced lead carbon battery. These have been applied to a Ford Focus project demonstrator which, for the first time, will be made available for public ride and drive evaluation by delegates at the Low Carbon Vehicle event (LCV2016), at Millbrook, UK.
Final testing has confirmed ADEPT’s key achievement of 10-12% reduction in fuel consumption (NEDC)—equivalent to sub-80g/km of CO2 emissions. According to the latest updated analysis of the potential cost of production implementation of ADEPT—conducted independently by Ricardo—the system would represent an incremental cost of in the region of €60 per gram/km of CO2 reduction. This is a result that makes the ADEPT powertrain architecture very competitive with other fuel economy solutions such as full hybridization, where costs of implementation can be significantly higher.

Study suggests focusing on cold starts in gasoline cars as target for emissions reduction
August 22, 2016
A new study suggests that focusing on a gasoline-fueled vehicle’s cold start is the best target for future design changes to reduce emissions of criteria pollutants. The researchers are presenting their work today at the 252nd National Meeting & Exposition of the American Chemical Society (ACS) in Philadelphia.
Although the Environmental Protection Agency (EPA) has reported that air is cleaner today than it was in the 1970s, more than 130 million people in the US still live in places where smog or particle pollution rises to unhealthful levels. Smog can cause coughing and shortness of breath, and can aggravate asthma or trigger asthma attacks. Much of this haze is formed from volatile organic compounds, or VOCs, and fine particulate matter from tailpipe emissions.

Audi developing electromechanical rotary dampers; potential for energy recuperation from suspension; 48V
August 10, 2016
Audi is developing a prototype electromechanical rotary dampening system called “eROT,” in which electromechanical rotary dampers replace the hydraulic dampers used today for an even more comfortable ride. The eROT system also offers the potential for energy recuperation from the suspension.
Every pothole, bump, and curve in the road induces kinetic energy during compression and rebound of the car’s suspension, observes Dr.-Ing. Stefan Knirsch, Board Member for Technical Development at AUDI AG. “Today’s dampers absorb this energy, which is lost in the form of heat. With the new electromechanical damper system in the 48-volt electrical system, we put this energy to use. It also presents us and our customers with entirely new possibilities for adjusting the suspension.”

Audi introducing quattro ultra: predictive, permanently available all-wheel drive for improved efficiency
February 20, 2016
For more than 30 years, Audi quattro has been a permanent all-wheel drive system. (Earlier post.) In 2015, more than 40% of all Audi customers chose a quattro model; the Audi Q5 topped the list with more than 260,000 units.
Audi is now introducing a new “quattro ultra” technology that combines driving dynamics and safety with high efficiency. With quattro ultra, the all-wheel drive is always deactivated when it is not needed, but remains permanently available, significantly reducing the potential fuel consumption difference between front-wheel drive and permanent all-wheel drive. The system is designed for numerous Audi models with longitudinally mounted front engines. An initial variant will debut in the new Audi A4 allroad quattro in mid-2016.

Pitt study reveals heat transfer mechanisms in MOF-based adsorbed natural gas storage; advancing the technology
January 22, 2016
Researchers at the University of Pittsburgh’s Swanson School of Engineering are working with metal-organic frameworks (MOFs) to develop a new type of natural gas storage system that would adsorb the gas like a sponge and allow for more energy-efficient storage and use. In the journal Physical Review Letters, the team reports on their study of heat transfer mechanisms in such systems, work that may advance the technology.
Traditional CNG tanks are empty structures that require the gas to be stored at high pressure, which affects design and the weight of the vehicle. Dr. Christopher Wilmer and his lab are instead focused on porous crystal/gas systems, specifically MOFs, which possess structures with extremely high surface areas. However, Dr. Wilmer notes, one of the biggest challenges in developing such an adsorbed natural gas (ANG) storage system is that the process generates significant heat which limits how quickly the tank can be filled.

Audi’s production electric e-tron quattro may set a new standard for vehicle handling; advanced vehicle dynamics control
December 01, 2015
The production version of Audi’s battery electric e-tron quattro SUV (earlier post), due out in 2018, is an important vehicle for the brand, and especially for Audi of America, which is driving many of the requirements for the C-segment electric SUV. At the LA Auto Show, Audi of America President Scott Keogh said that the brand is targeting at least 25% of its US sales to be e-tron—i.e., plug-in hybrid or full electric—models by 2025. (Earlier post.)
He also observed, in a conversation on the eve of the LAAS, that if an automaker can launch a defining product, the game changes. Audi intends for the e-tron quattro to become such a defining product—an Audi electric SUV in the high-volume C-segment that is reasonably priced (in the luxury sector) and delivers longer range along with all the “known” benefits of electric drive: speedy acceleration, quiet, lower cost of fueling, and zero tailpipe emissions (as well as the high-value HOV sticker for some markets). But to make this a benchmark product, Audi intends to go further, leveraging the three-motor electric quattro powertrain through very advanced software controls to deliver a ride and handling experience not possible even in an all-wheel drive electric vehicle equipped with a torque vectoring differential mechanism (e.g., a Tesla).

Frost & Sullivan forecasts Gasoline Particulate Filters to climb from 50,335 units now to 4.2-4.6 million units by 2020
November 08, 2015
Gasoline direct injection (GDI) is a strategy to improve fuel efficiency that is rapidly gaining market acceptance. However, unlike conventional gasoline engines, gasoline direct injection engines produce particulate matter, as do diesels, and emission controls will become an issue the technology must address as standards for particle mass tighten, and also as standards for particle numbers emerge.
In a 2013 study, a team from Ford’s Research and Advanced Engineering group in Dearborn noted that because the efficiency advantage of homogeneous GDI is not as large as with diesel engines, the use of gasoline particulate filters (GPF) is a less practical solution to PM emissions aftertreatment. Accordingly, there are significant research efforts—including Ford’s own—aimed at understanding how PM emissions can be reduced by engine design (e.g., fuel injection timing, number of injections, fuel pressure, injector placement, etc.) and fuel properties. (Earlier post.) Nevertheless, Frost & Sullivan projects the number of engines equipped with GPFs will climb from 50,335 units today to 4.2–4.6 million units by 2020. (“Analysis of the GPF Market for Passenger Cars in Europe and North America”)
