Injector 1, functions, requirements and type of function: the high-pressure diesel injection pump injector fed EAST engine brand, to a certain pressure, was mist sprayed into the combustion chamber. Requirements: ① ② spray evenly injection pressure and a certain range, and suitable injection cone angle ③ off the oil quickly, no drip phenomenon injector of the type currently used injectors injectors are closed, there is hole injector and injector pintle two kinds. Type: Vehicle diesel engine fuel injection pump according to their works can be divided into a plunger-type injection pump, fuel pump - injector and injection pump piston pump rotor distribution pumping principle has cut cylindrical surface of the plunger head chute, and through radial holes, and the top axial bore communicating with the aim of changing the amount of circulating oil; plunger has put into the system, back to the hole, all communication with the low pressure oil pump body cavity, the plunger suit EAST engine retail applications into the pump after screw positioning upper body. Plunger head chute different location, change the amount of oil by different methods. The oil valve and the oil valve seat is also a pair of precision coupling, paired grinding are not interchangeable, the oil valve is a one-way valve EAST engine market prices, under spring pressure, the upper conical valve seat surface and tight fit its role is to stop for the time, the upper end of the high-pressure tubing and the plunger cavity isolated to prevent the oil from flowing back into the high-pressure tubing inside the fuel pump. EAST engine brand, east of the engine, the engine is provided by Weifang East China East China Weifang Huadong Engine Co., Ltd. Weifang Huadong Engine Co., Ltd. (www.hdchai.com) strong, credible, in Shandong Weifang engine industry has accumulated a large number of loyal customers.
