摘要：
Reducing fuel consumption in automotive engines is a key enabler for CO2 emission reduction. Tribology plays a significant role in reducing parasitic losses in an engine and thus reducing fuel consumption. The paper reviews frictional losses in critical engine components and the lubrication regime(s) they operate. This reveals the opportunities for friction reduction at cylinder bore/piston contact, valvetrain, and bearings through deposition of low friction coatings, improved surface finish, surface modifications, and low friction engine oil. The paper also attempted to capture implementation of some of these friction reduction concepts in recent engines.
