What are the actuators and sensors in the engine electronic control system?

The actuators in the engine electronic control system include fuel injector, electronic throttle body, electronic independent ignition system, electric fuel pump, etc. They all work under various working conditions according to the instructions of the engine control unit.

Sensors include intake air temperature and pressure sensor, water temperature sensor, knock sensor, throttle position sensor, oxygen sensor, camshaft position sensor or crankshaft position sensor or both.

Engine Electronic Control System (EECS) is to electronically control the ignition, fuel injection, air-fuel ratio and exhaust emission of the engine, so as to make the engine work in the best working condition, thus achieving the purpose of improving its vehicle performance, saving energy and reducing exhaust emission.

Extended data:

The electronically controlled ignition device consists of a microprocessor, sensors, their interfaces and actuators. The device calculates and judges the engine parameters measured by the sensor, and then adjusts the ignition time.

It can make the engine work at the best ignition advance angle at different rotational speeds and air intake, make the engine output maximum power and torque, reduce oil consumption and emissions, save fuel and reduce air pollution.

When the engine is working, the device compares and judges the air flow, intake temperature, engine speed, working temperature and other parameters measured by each sensor with the fuel supply control parameters pre-stored in the memory under the best working conditions, and calculates according to the pre-programmed program.

Adjust the fuel supply in time to ensure that the engine always works in the best condition, so as to improve the comprehensive performance of the engine under the condition of outputting certain power.
