汽油／CNG两用燃料发动机控制系统开发
Development of control system for a CNG/gasoline bi-fuel engine
摘要
Abstract
The CNG/gasoline bi-fuel vehicle using CNG as the primary fuel and gasoline as a secondary has good economy and emission performance ,but the traditional bi-fuel engine uses master/slave dual ECU system cannot realize it .For improving the performance ,the research with multi-point sequential injection based on single ECU which is designed for OEM is made .The CNG special control strategies are designed such as Lambda PI control logic of Non-symmetric oscillation ,and also the experimental investigation for this bi-fuel engine and the emission test of vehicle are carried out .According to the experiment results ,the performance of engine with single ECU is better than the engine with master/slave dual ECU ,and the value of emission is less than euro IV emission levels when we use CNG fuel .关键词
