Description
Product Overview
The high-pressure fuel pump is driven by a cam to reciprocally compress gasoline, providing stable high-pressure fuel to the direct injection injectors in the cylinder. The electronic control components continuously feed back the oil pressure signal to the vehicle computer. Under long-term urban road bumps, cabin high temperatures, and gasoline impurities washing conditions, the piston seal may wear, the internal one-way valve may fail, and the electronic control sensor may age, resulting in slow oil pressure establishment, weak acceleration power, multiple ignitions during cold start, increased fuel consumption, and constant engine fault lights. This product is an integrated finished high-pressure fuel pump. The installation hole spacing, oil circuit threads, and electronic control plug specifications are standardized. The factory uniformly calibrates the standard supply pressure for standard fuel supply. Maintenance and replacement do not require additional calibration. It is suitable for home cars, urban SUVs, and gasoline direct injection power maintenance.
Core Advantages of the Single Product
Integrated aluminum pump body, lightweight, high rigidity, and high temperature resistance
The entire aluminum integrated shell is cast as one piece, with built-in reinforcing ribs, resulting in lower self-weight, excellent heat dissipation performance, and the ability to withstand continuous cabin high temperatures and road bumps and vibrations. It is less likely to deform or leak under long-term high-pressure conditions, and the shell is resistant to gasoline corrosion.
Double flange standard installation holes, precise alignment without offset
Standard fixed flange holes are reserved on both sides for precise installation positioning. The piston reciprocating motion has no eccentric wear, and after assembly, it fits the cylinder head surface, eliminating leakage from the pump base.
Spring piston boost structure, stable oil pressure output linearity
Built-in thick high-pressure reset spring + mirror-finished grinding piston pair. During reciprocation compression, pressure fluctuations are small, and standard track pressure can be maintained in both high and low speed conditions, eliminating low-speed hesitation and high-speed power deficiency problems.
Red and yellow dual-color oil circuit dust-proof protective caps, comprehensive protection of precise oil channels
Red sealing protective cap at the high-pressure outlet and yellow plug at the low-pressure inlet. They are used to seal the oil circuit during storage, transportation, and disassembly, preventing dust and impurities from entering the piston cavity and avoiding one-way valve jamming and oil pressure leakage.
Integrated electric control sensor connector on the side, precise oil pressure signal transmission
Integrated black waterproof electric control plug, with built-in pressure sensing element, which collects oil circuit pressure feedback to the vehicle computer in real time. The signal transmission is stable, eliminating false oil pressure alarms and false fault lights.
Factory complete oil pressure calibration, quick restoration of original factory power
The entire machine completes the detection of high and low pressure full working condition fuel supply pressure, sealingity, and electronic control signal matching. Products from the same batch have unified parameters. After replacement, idle speed is stable, acceleration is linear, and maintenance and debugging time is significantly reduced. Applicable scenarios
This product is suitable for family sedans and urban SUVs equipped with gasoline direct injection systems. It is applicable for urban commuting short-distance driving, outdoor alternating hot and cold conditions, and regular gasoline medium environment for passenger car direct injection engines with high-pressure fuel supply components replacement.
