摘要
介绍了一种汽油/CNG两用燃料车集成式电控系统的设计,这种控制系统将汽油和CNG的控制集成在单个ECU里,能够对两种燃料实现准确的喷射控制和点火角控制,并实现两种燃料状态下的OBD诊断。试验结果表明,这种电控系统能够满足国家排放法规要求,并大大降低成本。
Design of integrated electronic control system for gasoline/CNG dual fuel vehicle was introduced. The control sys- tem integrated the gasoline and CNG control in a single ECU, which could control the injection and ignition timing accurately, and realize OBD of dual fuel. The experimental results show that the electronic control system can meet the national emission regulations and cut the cost greatly.
