The biggest difference between electronically controlled engine and carburetor engine lies in the oil supply system. The fuel supply system of electronically controlled engine cancels the carburetor, but adds many electronic automatic control devices. It includes many sensors, actuators and ECU. ? The electronically controlled engine should not only accomplish the tasks that the carburetor has to accomplish, but also accomplish the tasks that the carburetor is difficult to accomplish.

Principle and development trend of electronic control system of automobile engine;

1, Engine Electronic Control System (EECS) electronically controls engine ignition, fuel injection, air-fuel ratio, exhaust emission, etc. Therefore, the engine can work in the best working condition, so as to improve its vehicle performance, save energy and reduce exhaust emissions.

2. Automotive electronic control technology has become an important symbol to measure the development level of modern automobiles. The automobile electronic control system is obviously developing towards integration, intelligence and networking.
