Construction machinery For 0445120067 Fuel Injector BOSOH D6E D7E Excavator Engine Parts

Specification

Description

Model 0445120067 common rail diesel fuel injector is a core engine spare part for construction machinery excavators, specially compatible with D6E and D7E series diesel engines, and widely used in the fuel injection system of various engineering excavation equipment. Manufactured with precision integrated forging technology in strict accordance with original dimensional specifications, this product supports direct replacement of old parts without modification or debugging. It is equipped with standard original packaging and undergoes dual inspections of high-pressure tightness and atomization accuracy before delivery. Adapted to high-intensity engineering working conditions, it perfectly matches the engine electronic control system to stably deliver high-pressure fuel, making it an ideal spare part for excavator engine maintenance and replacement.

Advantage

Original-level Precise Compatibility: Strictly replicates original installation dimensions and interface parameters for non-destructive direct mounting on D6E & D7E engines. Easy installation avoids oil leakage and misalignment failures, greatly cutting maintenance labor and modification costs.
High-strength Wear-resistant Material: The main body is precisely processed from high-strength alloy steel, with internal valve assemblies adopting high-pressure and wear-resistant precision components. It withstands long-term impact of high-pressure fuel, features corrosion and high-temperature resistance, and adapts to harsh construction site environments with dust, high and low temperatures.
Full-range Precision Factory Inspection: Every fuel injector passes high-pressure testing, atomization flow calibration and solenoid valve response detection with traceable process data, effectively eliminating common faults such as idling jitter, insufficient power and excessive fuel consumption.
Long Stable Service Life: The precision sealing structure with anti-aging sealing rings prevents fuel leakage and carbon accumulation inside the engine. Its service life is over 60% longer than ordinary aftermarket parts, lowering frequent replacement maintenance expenses.
In-stock Supply with Standard Packaging: Equipped with dust-proof and anti-collision independent protective packaging for fast delivery. Bulk purchase is supported to provide stable supply for machinery maintenance factories and parts wholesalers.

Performance

Excellent Fuel Atomization Performance: Designed with multi-hole precision nozzles, it delivers evenly atomized fuel under high pressure for sufficient air-fuel mixing and higher combustion efficiency. It improves engine power output, reduces diesel consumption and exhaust emissions, meeting National III and IV emission standards for construction machinery.
High-speed Electronic Control Response: Built-in high-precision solenoid valve realizes millisecond-level sensitive injection switch, supporting segmented pilot and main injection control. It ensures stable idling and linear power output under heavy-load frequent operation, effectively reducing engine vibration and operating noise.
Outstanding High-pressure Resistance: Stably adapts to the rated high-pressure working condition of common rail systems. The premium sealing structure prevents pressure relief and fuel leakage during long continuous operation, maintaining stable injection flow under extreme loads to guarantee fault-free full-load engine operation.
Accurate Flow Control Performance: Calibrated with standard injection flow before delivery to ensure high consistency of fuel supply across all cylinders. It avoids cylinder imbalance faults such as engine shaking and cylinder misfire, delivers smooth engine operation and extends the service life of crankshaft, piston and other auxiliary components.
