汽车电控（Automobile electronic control） Car electric control.Txt when you think you have nothing, you have at least time, time can heal all wounds, so please dont cry. A contented expectation is worth a wait; a willing hope is worth a fall. The secret to staying young is having a restless heart. It is not the quality of life that determines what tastes, but the quality that determines what life is. First, what are the effects of electronic control technology on the performance of the engine? 1, improve the power of the engine, 2, improve the economy of the engine 3, reduce pollution emissions 4, improve engine acceleration and deceleration performance 5, improve engine starting performance Two. What is called open-loop control? What is closed loop control? Which systems are controlled by closed loop? 1, in the control system, if there is no feedback loop between the output and the input, the output has no influence on the control function of the system, and the system is called open-loop control system. 2 、 in the control system, if there is a feedback loop between the output and the input, the output has a direct influence on the control function of the system, called closed-loop control system. Closed loop control is adopted for knock control, EGR control and spark advance angle feedback control. Three 、 What are the common sensor actuators in the electric control system? What are their respective functions? What is their abbreviation? 1, according to the ECU INJ fuel injector fuel injection pulse signal, the accurate measurement of fuel injection quantity 2, ignition ICM according to the ECU pulse signal to control ignition 3, idle speed control valve ISCV control engine idle speed 4, cruise control solenoid valve according to the ECU CCSV cruise control system 5, solar term door control engine TC based on the ECU control solar term door the opening of 6, according to the ECU EGRV exhaust gas recirculation valve EGR control valve IACV 7, intake air intake system base
