The Role of Injector of Forklift Diesel Fuel Supply System: The forklift engine fuel injector is installed on the cylinder head of a diesel engine and is a device that injects highpressure fuel into the combustion chamber of a diesel engine. It mainly consists of an injector and an injector body, and its installation position and angle on the cylinder head depend on the design of the combustion chamber. According to the requirements of different diesel engines, the diesel mist from the highpressure oil pump is injected into a specific position in the combustion chamber with a certain injection pressure, spray fineness, injection rule, range and spray cone angle, and is mixed with air for combustion.
