Description
Product Overview
The high-pressure common rail oil pump is driven by the engine power to establish a stable high-pressure fuel supply. It cooperates with the electronic control solenoid valve to adjust the fuel supply flow and rail pressure in real time, providing a constant high-pressure oil source for all the fuel injectors throughout the vehicle. Under long-term conditions of high cabin temperature and impurities in the diesel fuel, such as erosion from the fuel, the piston may wear, the solenoid valve may get stuck, and the pipeline seal may leak. This results in continuous fluctuations in rail pressure, delayed start-up, reduced vehicle power, and increased fuel consumption. This complete integrated oil pump is factory-tested for high-pressure resistance, flow matching, and aging tests under high and low temperatures, and is suitable for the major overhaul of light commercial diesel vehicles, small construction machinery, and diesel passenger cars' common rail fuel supply systems.
Unique core advantages of this single product
The aluminum pump body is integrally cast with reinforcing ribs, ensuring good heat dissipation, shock resistance, and preventing leakage.
The aluminum shell is integrally cast with reinforcing ribs on the outer wall, enhancing structural strength and preventing cracking and leakage even under long-term vehicle vibrations. The aluminum material has excellent heat conductivity, quickly dissipating the heat generated by the high-pressure fuel, reducing air resistance and piston jamming faults.
The entire pipeline is equipped with yellow dust-proof protective plugs, providing adequate protection during storage and transportation.
All the oil pump's inlet, outlet, and main shaft end are equipped with yellow sealing plastic plugs, isolating dust, water vapor, and accidental knocks and scratches from the precise oil circuit and main shaft. During storage and transportation, no impurities will enter the pump body, and it can be directly assembled upon arrival.
Dual-sized waterproof electronic control solenoid valve connectors for precise control of rail pressure.
The side is equipped with dual-color snap-type waterproof electronic control connectors, respectively controlling fuel supply measurement and pressure regulation. The internal waterproof rubber core isolates engine oil, water vapor, and electromagnetic interference, ensuring stable signal transmission and precise real-time adjustment of fuel supply flow, maintaining constant rail pressure.
Central standard drive main shaft, with no transmission slack or gap
The top standardized drive main shaft is compatible with the corresponding model's timing transmission structure, with precise positioning steps and limits, ensuring no slippage or gap in transmission, stable piston reciprocating stroke, and no problems of fluctuating fuel supply pressure.
Integrated multi-level oil circuit circulation structure, self-cleaning to reduce carbon deposits
The internal intercommunicating circulation oil circuit of the pump body allows for continuous circulation of diesel fuel through the oil circuit, removing gums and tiny impurities, reducing the probability of piston and solenoid valve jamming, extending the lifespan of the pump body, and reducing the cost of frequent disassembly and maintenance. Applicable scenarios
This product is suitable for light-duty diesel freight vehicles with electronic control common rail fuel supply system, small wheeled construction machinery, and light-duty diesel passenger cars. It is applicable for urban road transportation, light-load operations at construction sites, and outdoor operations in high temperatures, low humidity, and high dust conditions for the fuel supply system of small-sized diesel engines with electronic control common rail. It is suitable for major overhauls of the fuel supply system.
