Description
Product Overview
The electronically controlled common rail injector receives the ultra-high pressure fuel from the common rail pipe and, relying on the top electromagnetic component, receives the electrical control unit's signal to drive the internal precision valve芯 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 road driving， continuous erosion by impure diesel， alternating cold and hot vibrations in the engine compartment， the internal valve芯 sealing surface wears out， the nozzle's spray holes expand， and the internal sealing components 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 all installation dimensions， oil circuit interface specifications， and electromagnetic signal matching parameters standardized for processing. During maintenance， the entire set of injectors can be directly replaced， eliminating the cumbersome process of disassembling and debugging the internal precision components. It is suitable for the maintenance of light pickup trucks， light freight vehicles， small construction machinery， and small diesel generator sets.
Core advantages of this product：
The slender segmented composite alloy steel integrated cylinder body is rust-resistant， withstands pressure， and is not prone to deformation or oil leakage.
The cylinder body is segmented and formed by CNC machining of alloy steel， with surface passivation protection treatment， suitable for narrow cylinder head installation space， capable of long-term withstanding the continuous impact of high-pressure fuel， resisting diesel medium corrosion， engine compartment temperature differences， and thread not slipping， cylinder body not cracking or leaking， maintaining long-term high-pressure sealing performance of the oil circuit.
Side-mounted integrated dual oil inlet and outlet interfaces， smooth and stable oil circuit pressure track
The side edge integrates an integrated and formed inlet and return oil dual pipeline interface， without splicing gaps， reducing the resistance of high-pressure fuel flow， excess fuel can quickly return and relieve pressure， stabilizing the base oil pressure of the common rail system， eliminating the problem of excessive oil pressure at idle speed， and excessive single spray volume causing carbon deposits and black smoke in the cylinder.
Top-mounted integrated electromagnetic drive component， synchronous response without lag to the electrical control signal
The upper end is pre-assembled with a precise electromagnetic drive mechanism， the transmission of the electrical control signal is sensitive， the valve芯 reciprocating opening and closing action has no delay， precisely controlling the single spray volume and the opening timing of the spray， ensuring the engine 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， with internal precision multi-micro-hole atomization spray holes， the high-pressure fuel atomization particles are fine and uniform， the oil-gas mixture is sufficient， reducing carbon accumulation in the cylinder and reducing fuel consumption.
Built-in multi-layer oil-resistant sealing structure， bidirectional barrier against leakage and air backflow
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 backflow into the oil circuit after shutdown， avoiding slow oil pressure build-up when starting next time， and reducing the need for secondary calibration when installing the entire injector.
The entire machine is factory-tested under all working conditions， no need for secondary calibration when installed
The entire injector is independently tested for electromagnetic response speed， high-pressure sealing and pressure retention duration， atomization uniformity， and standard spray flow at the factory， with unified performance parameters after assembly， quickly restoring the engine's standard power output， significantly reducing the time for oil circuit maintenance and debugging.
