The fuel injector is mainly composed of a starting circuit, a cold fuel injector and a thermal time limit switch. The function of the cold start fuel injector is to inject fuel into the intake manifold when the engine is cold started to enrich the mixture and improve the engine. the cold start performance of the device.
Cold-start injectors, also known as auxiliary injectors or cold-start electric valves, improve engine low-temperature starting performance. The advantages and disadvantages of the cold start injector are as follows: 1. Advantages: To a certain extent, it can improve the difficulty of cold start of the engine. 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.
