What are the characteristics of electronically controlled engines?

1 to improve the uniformity of the mixture in each cylinder.

Using EFI multi-point injection, the fuel is near the intake valve of each cylinder, so that the concentration of mixed gas in each cylinder is basically the same, which is beneficial to reduce the emission of CO and HC.

2. Improve engine power and economy.

The electronic control gasoline injection system of automobile adopts microcomputer to control the accurate fuel injection quantity, thus improving the power and economy of the engine.

3. Reduce emission pollution.

The air-fuel ratio is controlled by oxygen sensor feedback to make it close to the ideal state, thus greatly reducing the emission of harmful substances such as CO, HC and nitrogen oxides. The emission of harmful substances can be further reduced by controlling the optimal ignition advance angle through exhaust gas recirculation and secondary air injection.

4. Make the engine working condition transition smoother.

When the operation of the automobile engine changes, the fuel injection quantity and timing can be quickly adjusted and controlled according to the feedback signals of various sensors, so as to provide the best air-fuel ratio suitable for this working condition, and improve the response speed of the automobile engine to acceleration and deceleration working conditions and the stability of working condition conversion.

5. Improve the adaptability of automobile engine to geographical environment.

In order to improve the adaptability of the engine to geographical and climatic environment, the performance of the engine will change greatly. Electronic control and gasoline injection system measure the intake air volume through volume flow, so as to timely correct the air-fuel ratio according to the atmospheric pressure and ambient temperature, so that the automobile can maintain good comprehensive performance under various geographical and climatic conditions.
