What is the role of Fuel Injector?

Fuel Injector is mainly composed of starting circuit, cold injector and thermal time limit switch. The function of cold start injector is to inject fuel into the intake manifold when the engine is cold started to enrich the mixture and improve engine performance. Device for cold start performance. Cold-start injectors, also known as auxiliary injectors or cold-start electric valves, improve engine low-temperature starting performance.

The advantages and disadvantages of Fuel Injector are as follows: 

1. Advantages: To a certain extent, it can improve the difficult problem of engine cold start.

2. Disadvantages: Due to the cold start injector injecting fuel into the intake manifold, there is a disadvantage of uneven fuel supply for each cylinder.
