广汽丰田凯美瑞轿车采用的1AZ-FE和2AZ-FE为自然吸气式电子控制燃油喷射发动机,其工作原理为发动机ECM根据各个传感器传来的各种信号,经实时处理和计算后,向各有关执行器发出指令,以控制最佳喷油时刻、喷油量和点火时刻,使发动机在各种状况下都处于最佳工作状态。加不起油是电喷发动机的一
The 1AZ-FE and 2AZ-FE used by GAC Toyota Camry sedan are naturally aspirated electronically controlled fuel injection engines. The principle of operation is the engine ECM. According to various signals from various sensors, the signals are processed and calculated in real time, The actuator issues commands to control the optimum injection timing, fuel injection amount, and ignition timing so that the engine will operate optimally under all conditions. Can not afford to add oil EFI engine
