Description
Product Overview
400903-00074D Electronic Fuel Injector is the core injection component of the common rail system in medium and small-sized diesel construction machinery. It is equipped with an electromagnetic control valve to precisely control the timing and amount of fuel injection. Long-term outdoor operations in dusty environments may lead to carbon deposits on the nozzle, wear of internal components, and leakage of seals. A complete set replacement can directly repair all fuel supply failures, reducing the downtime for equipment maintenance and repair, and is suitable for small excavators, agricultural tractors, light loaders, and mobile diesel generator sets for maintenance and replacement.
Unique Core Features of the Single Product
L-shaped lateral turning angle fuel inlet port, equipped with a yellow dust-proof protective cap
Lateral bent fuel inlet thread, suitable for narrow and compact cylinder head installation space, with no squeezing or bending of the pipeline layout; factory-pre-installed yellow plastic protective cap to isolate sand and impurities during storage and transportation, avoiding foreign objects entering the valve body and causing valve core jamming, reducing installation faults.
Extended segmented hardened alloy valve body, multi-layer sealing against high-pressure leakage
The valve body is processed by multi-stage integrated turning and hardening, and is equipped with multiple layers of oil-resistant ring-shaped seals, distributing the high-pressure impact force of the common rail layer by layer, making the sealing components less prone to aging and shrinking under long-term high-temperature conditions, and ensuring no oil leakage or carbon accumulation at the joint gap of the valve body.
The body is engraved with a unique identification QR code for easy model verification and control
The middle section of the valve body is engraved with an exclusive identification QR code, allowing repair stores to quickly verify the model and match the vehicle model, facilitating inventory classification management and reducing the probability of incorrect installation or dispatch.
Front-end equipped with copper sealing gasket, high-pressure sealing without pressure loss
The nozzle root is equipped with a high-temperature-resistant copper gasket, after assembly, it closely adheres to the cylinder head installation surface, filling the assembly gap, effectively blocking high-pressure fuel leakage, and stably maintaining the injection working pressure.
Precision micro-hole extended nozzle, fully combustible and reduces carbon black smoke
The front-end slender multi-micro-hole injection head, with fine and uniform high-pressure fuel atomization particles, promotes complete combustion of the mixture in the cylinder, significantly reduces black smoke emissions, slows down the rate of nozzle blockage, and extends the equipment maintenance period. Applicable scenarios
Suitable for small wheel excavators, agricultural tractors, light engineering loaders, and small diesel generator sets. It is applicable to outdoor construction sites and field operations in various temperature and dust conditions, including light to medium-load scenarios.
