OEM Customized Truck & Parts - SINOTRUK HOWO Truck Parts Fuel Injecter VG1560080022 – JieCheng

Basic information

1. The Fuel Injecter assembly is usually a whole composed of Fuel Injecter, governor and other components installed together;
2. The governor is a component that ensures the low-speed operation of the diesel engine and the limitation of the maximum speed, and ensures a certain relationship between the injection quantity and the speed;
3. The Fuel Injecter is the most important part of the diesel engine and is regarded as the “heart” part of the diesel engine. Once it fails, the entire diesel engine will malfunction.
The function of the Fuel Injecter is to atomize the fuel into finer particles and divide them into the fuel chamber to form a good flammable mixture with the air.
In addition to fuel supply, the diesel pump also controls the fuel injection quantity, speed, and fuel injection timing, and the oil pump is also used for fuel supply. The Fuel Injecter is mainly composed of four parts: the pump oil mechanism, the fuel supply adjustment mechanism, the driving mechanism and the Fuel Injecter body. Among them, the oil pump mechanism includes the plunger coupler, the oil outlet valve couple, etc.; the oil supply amount adjustment mechanism refers to the rack-type oil amount adjustment mechanism or the fork-type oil amount adjustment mechanism; the driving mechanism includes camshafts, tappet assemblies, etc. ; The Fuel Injecter body is the installation base of the above three, and it is required to have sufficient strength, rigidity and sealing, and to facilitate disassembly, adjustment and maintenance.Our products have undergone strict technical tests, and there will be no quality problems of the products themselves.
Our company has always been adhering to the tenet of ‘We don’t develop business, we build relationships through better service’

Wear and tear problems and their solutions
Reduced wear by adjusting shims
In actual production, the wear of adjusting gaskets is a common type of wear of the entire diesel Fuel Injecter. Our method of dealing with such problems should follow the following points:
(1) Measure and determine the wear degree of the adjusting gasket. If the measured wear amount is greater than 0.2 mm, it needs to be replaced. (2) Comprehensively analyze the clearance and wear of the roller, roller sleeve and pin shaft, and it is necessary to accurately measure the wear degree of the three. If we find that their wear is greater than 0.4 mm through measurement, we need to replace them in time.
(3) Calculate the actual cumulative wear amount of the components through the total wear degree of the camshaft and tappet. When the cumulative wear amount is found to be greater than 0.8 mm through measurement, it is necessary to determine the wear of the camshaft and the tappet assembly and each component in time. condition, and based on this, in accordance with relevant standards and guidelines, repair or replace the relevant worn parts. If there are parts with a relatively large degree of wear, they must be replaced, and simple maintenance cannot be carried out.
