Description
Product Overview
The electronically controlled common rail injector receives the ultra-high pressure fuel from the common rail pipe and relies on the top electromagnetic component to receive the electrical control unit's signal, driving the internal precision valve core to open and close rapidly, splitting the high-pressure fuel into fine oil mist and injecting it into the cylinder to complete combustion and power generation. Under long-term urban and rural long-distance transportation, construction dust operations, continuous erosion by impure diesel, alternating cold and hot vibrations in the engine compartment conditions, the sealing surface of the internal valve core will wear, the nozzle's spray holes will expand, and the internal sealing components will age and leak, resulting in imbalance in the fuel supply flow of a single cylinder, rapid pressure relief in the high-pressure oil circuit, attenuation of engine power output, and excessive black smoke emissions from the exhaust. This product has standardized processing for installation thread specifications, oil circuit interface dimensions, and electromagnetic signal matching parameters. During maintenance, the entire set of injectors can be directly replaced, eliminating the cumbersome process of disassembling and debugging the internal precision components, and it is suitable for medium-sized heavy-duty freight trucks, small and medium-sized wheeled loaders, small and medium-sized mining excavators, and fixed diesel generator sets for maintenance.
Core Advantages of the Single Product
Segmented composite alloy steel integrated cylinder body, double-layer rust-proof and pressure-resistant without deformation or oil leakage
The cylinder body is segmented and formed by CNC turning of alloy steel, with a black anodized surface and a combined protective treatment of metal polishing and blackening, which can withstand thousands of bar of high-pressure fuel impact for a long time, resist diesel medium corrosion, and withstand the temperature difference between the engine compartment, and the threads are not prone to slippage, the cylinder body is not prone to cracking or leaking, and maintains the high-pressure sealing performance of the oil circuit for a long time.
Side-mounted integrated inlet and outlet oil double interfaces, smooth and stable oil circuit pressure track
The side edge integrates an integrated double pipeline interface for inlet and return oil, without splicing gaps to reduce the resistance of high-pressure fuel flow, excess fuel can quickly return and relieve pressure, stabilize the base oil pressure of the common rail system, eliminate the problem of excessive oil pressure at idle speed and excessive single spray oil volume causing carbon deposits and black smoke in the cylinder.
Top-mounted integrated electromagnetic drive component, synchronous response without lag
The upper end is pre-assembled with a precise electromagnetic drive mechanism, the transmission of the electrical control signal is sensitive, the valve core's reciprocating opening and closing action has no delay, precisely controlling the single spray oil volume and the opening timing of the spray, ensuring the engine's idle speed is stable, the acceleration power is linear without jolts.
Front-end multi-level stepped limit nozzle, coaxial positioning for uniform atomization particles
The front-end multi-level stepped limit positioning structure automatically locks when installed in the cylinder head installation hole without deviation, and the internal is equipped with precise multi-micro-hole atomization spray holes, the high-pressure fuel is atomized into fine and uniform particles, the oil and gas are mixed fully, reducing the accumulation of carbon deposits in the cylinder and reducing fuel consumption.
Built-in multi-layer oil-resistant sealing structure, bidirectional prevention of leakage and air suction
The cylinder body is equipped with multiple specifications of oil-resistant fluorine rubber sealing gaskets, layering to isolate high and low pressure oil circuits, preventing high-pressure fuel from leaking out through assembly gaps, and also preventing air from being sucked back into the oil circuit after shutdown, avoiding slow oil pump pressure building up during the next start.
Whole-machine factory calibration under all working conditions, no need for secondary adjustment when installed on the vehicle
The entire injector is independently tested on the machine for electromagnetic response speed, high-pressure sealing and pressure retention time, uniformity of atomization, and standard spray flow, with unified factory performance parameters. After assembly, it quickly restores the engine's standard power output, significantly reducing the time for oil circuit maintenance and debugging.
