Abstract

It is a difficult problem to precisely control a gasoline engine used by a Hybrid Electrical Vehicle (HEV) operating in high efficient states because of the engine's uncertain fuel consumption characteristics. The problem can be resolved by setting up an efficiency model for the engine to implement feedback control. Based on theoretical analysis and a large number of experimental investigations on a LJ491QE1 and a 4G18-AA gasoline engine, the theory was presented that using equivalent air exchange loss or experience equivalent air exchange loss as a general efficiency model for naturally aspirated port fuel injection gasoline engines used by the HEV can determine the dynamically varied engine efficient working region. The experience equivalent air exchange loss which only used two parameters of an intake air pressure and an exhaust gases pressure can determine the dynamically varied high efficient working region of the engines and it has a better responsiveness than the equivalent air exchange loss.
