The company is working on a net-generation configuration combining VCR with stoichiometric charges and cooled EGR to improve part-load efficiency by means of both a reduction in heat and pumping losses. When running at part loads, the engine operates at high compression ratios to minimized BSFC and maximize the sweet spot on the map.

Researchers at Tianjin University in China report that combing split injection to the Miller cycle with boost pressure can effectively decrease the knock tendency and increase the engine torque in a downsized spark-ignition engine. High boost pressure can compensate for the decreased intake charge of the Miller cycle.

CPT says that the RegEnBoost system enables a typical family-sized car to achieve less than 100 g/km CO 2 with a 1-liter gasoline engine, but when required can offer the same lively performance and in-gear acceleration of a 2-liter naturally aspirated powertrain. Hence the industry trend to dual-charging systems, CPT notes.
