电子燃油喷射技术是保障多工况下发动机空燃比为最佳状态，它是经工作参数采集，喷油量查询，用脉动喷油的时间控制实现的。为达到节能、降污、增大动力的目的，电脑还有开环、闭环的控制模式，以及点火提前角控制和自诊断系统组成了适用的发动机管理系统。 Electronic fuel injection technology is to protect the engine air-fuel ratio under the best conditions for the best, it is collected by the operating parameters, fuel injection inquiries, pulsating fuel injection time control achieved. In order to save energy, reduce pollution, increase power purposes, the computer also open-loop, closed-loop control mode, and ignition timing control and self-diagnosis system constitutes a suitable engine management system.
