Description
Product Overview
The VE distributed fuel injection pump is driven by the engine gears and distributes high-pressure fuel to each cylinder through internal pistons. It controls the fuel injection volume through a mechanical speed regulation mechanism and uses an electromagnetic valve to cut off fuel supply during engine shutdown. Over time, due to prolonged high-temperature vibrations in the engine compartment, impurities in diesel, and fatigue of the speed regulation spring, issues such as uneven fuel supply, idle vibration, weak acceleration, engine shutdown stalling, and difficulty in cold start may occur. This product is an integrated finished fuel injection pump. The entire machine is calibrated for full operating conditions in terms of flow rate and timing upon factory assembly. The mounting flange, oil outlet thread, and drive shaft specifications are standardized, allowing for direct assembly on the cylinder side. It is suitable for maintenance of light trucks, pickups, agricultural construction machinery, and small diesel generator sets with mechanical direct injection fuel supply systems.
Unique Core Advantages of the Individual Product
Lightweight and thickened aluminum alloy casting pump body, with excellent heat dissipation and vibration resistance
The entire aluminum alloy is formed through a single press molding process, with strengthened ribs on the outer wall, ensuring high heat dissipation efficiency and reducing thermal deformation in the engine compartment under long-term high-temperature conditions; the shell has sufficient rigidity to withstand continuous vibrations from the engine, reducing internal piston gap offset and eliminating internal leakage and pressure relief.
Precise keyway output shaft at the front end, ensuring no slippage in power transmission
The end with quenched keyway drive shaft, which tightly meshes with the transmission gears, ensures stable and continuous fuel supply without power loss, and stable transmission in heavy-load climbing conditions without a decrease in fuel supply flow.
Multiple independent high-pressure oil outlet connectors, ensuring balanced fuel supply to each cylinder
The upper multi-channel standardized oil outlet thread interface, combined with a sealing locking nut, allows each cylinder's oil circuit to be independently allocated, with factory calibration of the fuel supply difference for each cylinder, ensuring uniform combustion and reducing black smoke emissions.
Side electromagnetic fuel cut-off valve for quick start-stop control of the oil circuit
A companion external electromagnetic cut-off valve with wiring harness, which cuts off fuel supply when powered on and immediately stops when power is cut, ensuring stable engine shutdown and eliminating dripping oil during shutdown and carbon buildup exacerbation; waterproof and insulated wiring harness connectors are resistant to diesel and oil corrosion.
Mechanical speed regulation adjustment mechanism at the top, suitable for adjusting fuel quantity in various operating conditions
An external mechanical speed adjustment lever and adjustment screw allow for fine-tuning of idle speed and rated fuel supply volume, suitable for different operating conditions such as empty load and heavy load, and for use in agricultural and short-distance transportation scenarios.
Standard double-hole oil circuit flange at the bottom, convenient for disassembly and assembly
The bottom is reserved standard oil inlet mounting flange holes, which fit the engine oil circuit base, ensuring uniform assembly force, combined with a sealing gasket without oil leakage, and simple maintenance and disassembly operations. Applicable scenarios
This product is suitable for light-duty freight vehicles, diesel pickups, agricultural tractors, small wheeled construction machinery, and fixed small diesel generators equipped with the VE mechanical distributed injection system. It is applicable for short-distance urban transportation, light-load operations in farmland, and lightweight machinery in outdoor high and low temperature environments for direct injection diesel engine fuel supply replacement.
