CMU study compares lifecycle GHGs of natural gas pathways for MHDVs; MD BEVs can deliver large reductions, but diesel hard to beat for Class 8
May 27, 2015
A study by Carnegie Mellon University researchers comparing life cycle greenhouse gas (GHG) emissions from different natural gas pathways for medium and heavy-duty vehicles (MHDVs) found that the GHG reduction potentials of the pathways vary sharply between non-Class 8 MHDVs (e.g., pick-up trucks, parcel delivery trucks, and box trucks), Class 8 transit buses, and Class 8 MHDVs (e.g., refuse trucks and tractor-trailers).
Battery-electric (BEVs), LPG, and CNG pathways could reduce life cycle GHG emissions for non-Class 8 MHDVs compared to the baseline petroleum fuels. Similarly, BEVs achieve emission reductions for transit buses. On the other hand, none of natural gas pathways, CNG, LNG, and F-T liquids, achieve any emission reductions per unit of freight-distance moved for Class 8 trucks compared to conventional diesel. The study is published in the ACS journal Environmental Science & Technology.
Volvo Trucks introduces automatic all-wheel drive for improved driveability and fuel economy
May 13, 2015
Volvo Trucks is introducing automatic all wheel drive—a feature it calls Automatic Traction Control—on construction trucks. ATC activates the drive on the front axle automatically when in motion, if the truck risks getting stuck—i.e., when the rear wheels lose traction on slippery or soft ground. The driver enjoys improved maneuverability, and the owner benefits from lower fuel consumption and less wear and tear on the truck.
The solution consists of software connected to the wheel speed sensors which detect and control wheel drive. When a rear wheel starts to slip, the power moves automatically to the front wheels without the truck losing torque or speed. A dog clutch activates the front-wheel drive in just half a second. The clutch is lighter and has fewer moving parts than a traditional solution with permanent all-wheel drive. If the driver encounters particularly rough ground, then it is possible to manually lock the other differentials at both front and rear.

Study: natural gas heavy-duty trucking fleet could benefit economy, but has mixed environmental effects
February 20, 2015
Switching from diesel fuel to natural gas may hold advantages for the US heavy-duty trucking fleet, but more needs to be done to reach the full environmental benefits, according to a new white paper released by the Institute of Transportation Studies at the University of California, Davis, and Rice University.
The recent shale-driven emergence of natural gas as an abundant, inexpensive fuel in the US has raised the possibility of a “momentous shift” in the level of natural gas used in transportation. The cost advantage of natural gas over diesel fuel is particularly appealing for vehicles with a high intensity of travel and thus fuel use. In the paper, the team investigated the possibility that natural gas could be utilized to provide fuel cost savings, geographic supply diversity and environmental benefits for the heavy-duty trucking sector—and whether it can enable a transition to lower carbon transport fuels.
ICCT reviews real-world tractor-trailer fuel economy in US, China and Europe
February 15, 2015
The International Council on Clean Transportation (ICCT) has published a new paper reviewing and summarizing data on commercial vehicle sales and real-world fuel consumption for heavy-duty tractor-trailers in the three key markets of the US, China and Europe, which together account for more than 70% of HDV sales worldwide.
The review found that in the US, average tractor-trailer fuel consumption rates for the entire fleet are approximately 39 L/100 km (6 mpg). For the newest US models, fuel consumption is typically between 33 and 36 L/100 km (6.5–7 mpg). A fleet-wide analysis done for the European Commission estimates tractor-trailer fuel consumption at roughly 31 L/100 km (7.6 mpg), while tests of individual vehicles done by trucking magazines suggest somewhat higher average rates of consumption at approximately 36 to 38 L/100 km (6.5 to 6.2 mpg). Chassis dynamometer testing performed as part of the regulatory development process in China reveals that tractor-trailers seem to have much higher fuel consumption rates, on average, than in the US and the EU, with laboratory results yielding an average of 44 L/100 km (5.4 mpg).

Ricardo study finds retrofitted Euro III bus can emit less NOx than newer Euro V hybrid
November 28, 2014
Measurements by Ricardo found that an older Euro III bus retrofitted with a selective catalytic reduction and continuously regenerating particulate trap system can be cleaner in terms of lower NOxemissions than newer Euro V hybrid buses.
The measurements of the retrofitted Euro III bus were an extension of a study of the Brighton & Hove Bus and Coach company fleet in partnership with HORIBA examining the real-world emissions of buses operating through a known pollution hot spot in Brighton city center. As a result of that study, Ricardo published results earlier in the year demonstrating the important role that improving traffic flow can have upon reducing NOx emissions. That study, the findings of which were reported in July, focused on a range of buses including Euro IV, Euro V conventional and Euro V hybrid vehicles.
Bus maker Alexander Dennis to fit GKN Gyrodrive flywheel hybrid systems to 250 buses; partners on international development
November 24, 2014
|Gyrodrive. Click to enlarge.|
Alexander Dennis Limited (ADL), Britain’s biggest bus and coach manufacturer, has chosen GKN Hybrid Power as a preferred partner and committed to the purchase of 250 of its Gyrodrive electric flywheel hybrid systems (earlier post). ADL will focus initially on the introduction of the low emission technology to bus fleets in London and Oxford but anticipates rapid deployment across the UK in the next few years. It will also be working closely with GKN to develop the technology for international markets.
Instead of a battery, the Gyrodrive system uses a magnetically loaded high-speed carbon-fiber flywheel to store the energy generated by a bus as it slows down to stop. It then utilizes the stored energy to power a GKN EVO electric motor which helps accelerate the bus back up to speed, generating significant fuel savings of up to around 25% at a considerably lower cost than battery-hybrid alternatives.

GKN to supply 500 electric flywheel hybrid drive systems to Go-Ahead Group for buses
July 29, 2014
UK transport operator Go-Ahead Group has ordered 500 electric flywheel Gyrodrive systems from GKN Hybrid Power for use in buses. The Gyrodrive Kinetic Energy Recovery System (KERS) system (featured in Audi’s LeMans-winning R18 e-tron quattro) harvests braking energy normally lost as heat.
When the driver brakes, a traction motor on one of the axles slows the vehicle, generating electricity at the same time. This electricity is used to charge the flywheel, spinning it at up to 36,000 rpm. When the driver accelerates, the system works in reverse. The energy is drawn from the flywheel and converted back into electricity to power the traction motor, which helps accelerate the bus back up to speed, generating fuel savings of more than 20% at a significantly lower cost and weight (60 kg, 132 lbs) than battery hybrid alternatives. Useable stored energy is 1.2MJ, with peak power of 120kW.

July 18, 2014
|Basic elements and operating principle of the diesel fuel-cell APU. Click to enlarge.|
At the upcoming IAA in Hanover, automotive supplier Eberspächer is presenting a fuel-cell APU (auxiliary power unit) for commercial trucks that converts diesel efficiently to electricity and thereby supplies the required power to all on-board consumer components such as the air-conditioning system or the refrigerator units.
As a result, the load for electricity generation can be taken off the engine or generator with a resulting decrease in fuel consumption and emissions. In future generations of trucks, components still driven mechanically today could thus be powered electrically at considerably less expense, the company suggests.

June 17, 2014
|I-Shift Dual Clutch provides seamless power delivery. Click to enlarge.|
Volvo Trucks is now launching I-Shift Dual Clutch, the first transmission on the market with a dual clutch system for heavy vehicles. With power-shift gear changes without any interruption in power delivery (with the exception of the range-change, which takes place when shifting from 6th to 7th gear), the 12-speed transmission maintains torque, and the truck does not lose any speed during gear changes. For the driver, the result is more comfortable and efficient progress on the road.
Transmissions with dual clutches are already used in cars, but Volvo Trucks is the first manufacturer to offer a similar solution for series-produced heavy vehicles. Volvo Trucks says that fuel consumption with the base I-Shift Dual Clutch is the same as with regular I-Shift. The company is offering two software packages to improve fuel economy with the unit:
