파워트레인 냉각 시스템 효율 개선 방안에 대한 연구

A lot of research has been done on power train cooling system to reduce fuel consumption and emission. Known engine cooling techniques are an electric water pump with an electric thermostat, an electric water valve, a clutch water pump and so on. The common approaches to enhance fuel economy among these techniques are fast warm up and control coolant temperature high. This paper discuss the amount of fuel economy enhancements on a engine with fast warm up technique, control coolant temperature high, control automatic transmission fluid temperature high.
