SwRI D-EGR gasoline demo vehicle delivers diesel efficiency at lower cost; potential for LEV III/Tier 3 emissions

Green Car Congress

improvement in city fuel economy (24.5 mpg) and a 9.2% D-EGR is a SwRI-developed gasoline engine concept that uses in-cylinder fuel reforming to produce CO and H 2 (with Research Octane Numbers of 106 and 130, respectively) and high levels of recirculated gas (EGR) to achieve very high levels of thermal efficiency.

Chevy Cruze diesel’s variable-swirl mechanism

Green Car Congress

During variable swirl, each throttle valve varies how much it opens to create mixture-motion of air and fuel within each cylinder. Cruze’s diesel offers a segment-leading EPA-estimated 46 mpg highway (5.1 In Cruze’s variable-swirl intake manifold, each cylinder has two separate intake ports, with one of them controlled by a valve.

Researchers propose evaluating alt fuel efficiency based on energy rather than volume; impact of ethanol on vehicle efficiency and GHGs

Green Car Congress

Relative changes in vehicle energy efficiency (VEE) (km/MJ) on ethanol/gasoline blends over those on gasoline for different blending levels. Several recent highly cited LCAs that have incorporated vehicle efficiency differences between gasoline and ethanol/gasoline blends could potentially be misleading. Click to enlarge.

Ford researchers: global light-duty CO2 regulatory targets broadly consistent with 450 ppm stabilization

Green Car Congress

Further, the study compares 450 ppm LDV CO 2 glide paths derived using only vehicle efficiency improvements against those derived using both vehicle and fuel actions. The SMP model calculates 2000?2050 They converted from an absolute amount to scale relative to 2000. Because of the high LDV emissions in 2000?2010,
