Diesel engine is an internal combustion engine with diesel fuel. Diesel engines are compression ignition engines of construction machinery brands, it's often the main inventor of the Diesel name was called Diesel engine. Diesel at work, the intake air engineering machinery diesel engine cylinder engine, because the movement of the piston subjected to high temperatures higher degree of compression Shandong Engineering Machinery Engine, reaching 500 ~ 700 ℃ in. Then the fuel mist sprayed into the hot air, the combustible mixture formed by mixing with hot air, automatic ignition and combustion. The role of energy released during combustion piston engine with a top surface of the engineering machinery manufacturers, and by pushing the piston rod and crankshaft rotation is converted to mechanical work. An injector, function, requirements and the type function: the high-pressure diesel injection pump injector supply to a certain pressure, mist sprayed into the combustion chamber. Requirements: ① ② spray evenly with a certain injection pressure and range, and suitable injection cone angle ③ off the oil quickly, no drip phenomenon of the type currently used injector injector injectors are closed, there is hole injector pintle injector and two kinds.
