Use of Supercritical Diesel Fuel for Improved Efficiency and Reduced Emissions

Green Car Congress

An experimental P-T diagram mapping the liquid, liquid-vapor, and SC regions for diesel fuel-CO 2 mixtures with different compositions and densities (numbers in red and black, respectively). Energy & Fuels 2009. George Anitescu from Syracuse presented the work in a poster at the DEER 2009 conference in Dearbon, Michigan.

Concept: Downsized and Supercharged Hybrid Pneumatic Engine for 30%+ Reduction in Fuel Consumption

Green Car Congress

Schematic of downsized and supercharged four-stroke hybrid pneumatic spark injection engine. The reduction in fuel consumption is obtained mainly through enabling the effective use of a heavily downsized engine, rather than from regenerative efficiency. The major part of this gain is due to downsizing the engine. Earlier post.).

ADEPT project to apply gasoline engine HyBoost system to diesel; 48V architecture; full hybrid fuel economy at much lower cost

Green Car Congress

The Ricardo-led Advanced Diesel Electric Powertrain (ADEPT) project will apply 48V “intelligent electrification” concepts, mild hybridization and waste heat recovery in a Ford Focus diesel demonstrator. version of its vehicle (a 2009 Ford Focus) but with fuel economy and CO 2 emissions approaching those of a Prius.

Advanced Turbocharged, Direct Injected Gasoline Engines Poised to Take on Diesels in US and in Europe for Reduced Fuel Consumption and Emissions

Green Car Congress

Additionally, suggested one of the speakers, advanced SIDI (spark-ignited, direct-injection) engines can take light-duty market share back from diesels in Europe based on the same trends. Some of the best passenger vehicles today, the ones called PZEVs, are pretty close to zero emissions. Comparison of Emission Standards (g/mi). .

Ford E85 Direct Injection Boosting Study: A Less Expensive Alternative to Diesel

Green Car Congress

The resulting higher BMEP levels allow downsizing of the engine at equivalent vehicle performance. Furthermore, by enabling higher CR, downsizing and downspeeding, E85 DI + gasoline PFI makes the engine more efficient in itsusee of gasoline. Earlier post.) PFI engine in a Ford F-150 pickup truck.

PSA to commercialize SwRI-developed Dedicated-EGR technology in high-efficiency gasoline engines by 2018

Green Car Congress

In the inaugural study reported in an SAE paper in 2009 (2009-01-0694), SwRI ran a 4-cylinder engine with cylinder 1 exhausting directly to the intake manifold, leading to a constant 25% EGR level. PSA concept D-EGR engine. Click to enlarge. Despite the benefits of EGR—e.g.,
