All three engine BSFC curves correspond to an engine speed of 2000 rpm.Click to enlarge. The new engine will achieve high efficiency using the Atkinson Cycle with an 18:1 compression ratio, combined with aggressive engine downsizing. Engine downsizing is a key tool in improving fuel economy. Earlier post.). Earlier post.).

However, most life cycle analyses (LCAs) to date have mainly focused on the production stage while assuming end-use efficiencies are the same for ethanol and gasoline despite the fact that ethanol can, in theory, affect engine efficiency and performance due to different thermo-chemical properties compared to gasoline. Policy implications.

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). However, towards a production solution, significant issues remain. BSFC of 280 g/kWh was measured at 2000 rpm-2bar BMEP.
