Made in China Diesel Fuel Injection Pump 22100-5D180 Injector Fuel Pump Spare Part for Toyota

Function: Increase the diesel pressure, deliver high-pressure diesel to the injector in a timely and quantitative manner according to the engine's working order and load size, and the fuel supply pressure of each cylinder is equal.
Requirements:
(1) The pump oil pressure must meet the requirements of injection pressure and atomization quality.
(2) The fuel supply should meet the precise quantity required for the diesel engine to work.
(3) Ensure accurate fuel supply within the specified time according to the working order of the diesel engine.
(4) The fuel supply amount and fuel supply time can be adjusted, and ensure uniform fuel supply to each cylinder.
(5) The fuel supply pattern should ensure complete combustion of diesel.
(6) The start and end of fuel supply should be agile, the fuel cut-off should be clean, and oil dripping should be avoided.
Type: The fuel injection pump of a diesel engine can be divided into three categories according to its working principle: plunger injection pump, injection pump-injector and rotor distribution injection pump.

There is an inclined groove cut on the cylindrical surface of the plunger head, which is connected to the top through radial holes and axial holes. The purpose is to change the circulating oil supply; the plunger sleeve is made with inlet and return oil holes, which are connected to the low-pressure oil chamber in the pump upper body. After the plunger sleeve is inserted into the pump upper body, it should be positioned with positioning screws.
The position of the inclined groove on the plunger head is different, and the method of changing the oil supply is also different. The oil outlet valve and the oil outlet valve seat are also a pair of precision parts, which cannot be interchanged after matching and grinding.
