Eaton contributing several components to DOE SuperTruck II program

Green Car Congress

The long-term objective of the project is to develop technology that can lead to cleaner, more efficient heavy-duty trucks, which haul 80% of goods in the United States and use about 28 billion gallons of fuel per year, accounting for around 22% of total transportation energy usage.

Dearman begins on-vehicle testing of Gen 2 transport refrigeration system powered by liquid air engine; lighter, more efficient

Green Car Congress

Since then the Dearman engine has been re-designed and it is already proving to be 30% lighter, 30% smaller, and 30% more efficient than its predecessor. The Dearman liquid air engine is an innovative heat engine that uses liquid air (or liquid nitrogen) as a “fuel” and emits cold air as exhaust. Earlier post.) Click to enlarge.

Use of Supercritical Diesel Fuel for Improved Efficiency and Reduced Emissions

Green Car Congress

Heat required to bring the fuel to SC states is recovered from the exhaust gas of the engine. To attenuate that risk, the researchers use a diluent such as CO 2 , H 2 O or exhaust gas. Diffusivity experiments and design/constructing of a SC fuel injector are in progress. Anitescu et al. DEER 2009). Transonic’s TSCi technology.

BorgWarner R2S two-stage turbo boosts performance of new top-end Ford 2.0L diesel

Green Car Congress

One compact KP35 high-pressure turbocharger generates boost pressure at low exhaust gas flow rates for rapid acceleration at low engine speeds without delay or turbo lag. As engine speed increases, the exhaust gas stream is split, and the larger K04 low-pressure turbocharger works in series with the KP35 high-pressure turbocharger.

FEV analysis of automotive-scale Pinnacle opposed-piston engine finds potential for significant increases in fuel economy

Green Car Congress

The design merits continued development for automotive application. liter, 3-cylinder design of the Pinnacle engine, as well as a downsized, turbocharged 750cc Pinnacle design. Boosting the engine through either turbocharging or supercharging allows improved fuel economy through downsizing or downspeeding the engine.

Using the PHEV (Plug-In Hybrid Electric Vehicle) to Transition Society Seamlessly and Profitably From Fossil Fuel to 100% Renewable Energy

Green Car Congress

The alternative-fuel car evolved to reduce exhaust emissions and other problems derived from burning fossil fuels. The use of the electric grid for energy transfer is not well understood, much less addressed by designers of other electric and alternative fuel vehicles. by Professor Andrew Alfonso Frank.
