Description
Product Overview
The four-cylinder mechanical fuel injection pump is driven by the engine camshaft to cause the plunger to reciprocate, thereby establishing high-pressure fuel. The top detent fork synchronously controls the fuel supply volume for the four cylinders, delivering high-pressure fuel to each cylinder of the four-cylinder engine. Under long-term field and construction conditions exposed to high and low temperatures, as well as diesel containing impurities, the plunger may wear, the oil valve seal may fail, and the oil pipe joints may leak. This may result in unstable fuel supply pressure, uneven fuel injection in each cylinder, power loss, and leakage from the cylinder cover. This product's pump body is fully equipped with a complete set of installation connectors and sealing gaskets, and is factory-tested for high-pressure sealing, fuel supply uniformity, and idle oil volume. No additional sealing fasteners need to be purchased. It is suitable for the overhaul of fuel supply systems of agricultural tractors, small loaders, and diesel generator sets.
Unique Core Advantages of the Single Product
Aluminum alloy die-cast integrated pump body with strengthened ribs for heat dissipation and vibration resistance
The entire aluminum pump housing is die-cast, with a single-piece outer wall formed with strengthened ribs, enhancing structural strength and reducing cracking under operational vibrations; the aluminum material has strong heat conductivity, quickly dissipating the heat generated by high-pressure fuel, reducing air resistance and plunger jamming faults, and achieving lightweight design to lower the overall load of the machine.
Four-cylinder independent plunger fuel supply unit, with synchronized and balanced fuel supply for each cylinder
Four sets of independent nitrided and hardened plunger components are inside, paired with high-temperature-resistant reset springs. The factory precisely calibrates the differences in fuel injection volume for the four cylinders to eliminate idle jitter, single-cylinder lack of power, and exhaust black smoke color differences, achieving linear and stable power output.
Comprehensive set of high-pressure oil pipe connectors + double-layer copper alloy gaskets, one-stop assembly
The kit includes a direct high-pressure connector, ball joint oil pipe connector, two thickened and high-temperature-resistant copper alloy seals, a complete set of sealing accessories for the oil pump inlet and outlet pipelines, and the copper alloy seals deform and fit tightly under high-temperature conditions, preventing high-pressure fuel leakage and pressure drop.
Top linkage fuel quantity adjustment detent fork, unified control of the entire machine's fuel injection volume
The four sets of linkage adjustment detent forks on the pump body can be synchronized and linked to the speed control mechanism to uniformly adjust the fuel supply volume for the four cylinders, quickly improving problems such as insufficient acceleration, excessive black smoke emissions, and high fuel consumption. The assembly alignment is simple and convenient.
Built-in circulation guide oil channels, self-cleaning to reduce impurity accumulation
The internal intercommunicating circulation oil path of the pump body allows diesel to continuously circulate and wash the oil path, removing gums and tiny impurities, reducing the probability of carbon deposits on the plunger and oil valve, extending the overall lifespan of the pump, and reducing the cost of frequent disassembly and maintenance. Applicable scenarios
This product is suitable for agricultural tractors with four-cylinder mechanical diesel engines, small wheeled loaders, light engineering equipment, fixed diesel generators, and is applicable for diesel fuel supply systems maintenance and replacement of small-sized mechanical diesel equipment used in field farming, short-distance construction site operations, and outdoor environments with high temperatures, humidity, and dust. It is suitable for repairing and replacing the diesel fuel supply systems of small-sized four-cylinder mechanical diesel power equipment used in fields, construction sites, and outdoor environments with high dust levels and varying temperatures and pressures.
