Opportunities for Electrified IC Engines
The automotive industry is polarized between external pressures for ‘zero’ emission battery electric vehicles (BEV) and the ability to manufacture them economically and with minimal environmental impact. Most predictions of future BEV market share suggest that the IC engine has an important role to play in personal transportation for the next several decades. That engine will very likely be part of a hybrid architecture. Accepting that the engine will be part of a hybrid powertrain permits new design rules and strategies for the IC engine. A major characteristic change of the engine will be to reduce BMEP, power density and engine speed requirements as performance demand will be supplemented by electric machines. This paper focuses on some simple changes to the IC engine to increase thermal efficiency with the knowledge of the supplemental electric energy.
