Recent passenger car engine characteristics and their tribological issues are explained. Hybrid engine is characterized by its frequent stop and start and low temperature operating condition, and downsizing turbo engine is characterized by direct fuel injection and frequent boosted operating condition. Recent friction reduction technologies are also explained considering their trade-offs such as wear, noise and oil consumption, in terms of piston, piston rings, cylinder, crankshaft, bearings and oil.
