IEA: carbon intensity of global energy supply has barely changed in last 20 years; “window of opportunity in transport”

Green Car Congress

Since 1990, however, the ESCII (2010 = 100) has remained essentially static, changing by less than 1%. tCO 2 /toe); in 2010 it was 56.7 In 2012, sales of hybrid-electric vehicles passed the one million mark. Engine downsizing and weight reduction represent around 30% of that potential collectively. tCO 2 /TJ (2.39

DOE awards Envera $2.8M to develop and to test efficient variable compression ratio engine

Green Car Congress

The new engine will achieve high efficiency using the Atkinson Cycle with an 18:1 compression ratio, combined with aggressive engine downsizing. Valve events will also be adjusted with the VVA to trap more air in the cylinders when power is needed. Engine downsizing is a key tool in improving fuel economy. Earlier post.).

Promising Delphi 1st-gen Gasoline Direct Injection Compression Ignition engine meeting ultra fuel efficient program targets

Green Car Congress

GDCI engine was significantly better than advanced production spark injection gasoline engines, and comparable to very efficient hybrid vehicle engines at their best efficiency conditions (214 g/kWh). This early work established that gasoline-like fuels with high resistance to autoignition are preferred for PPCI. Background.
