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 road driving, continuous erosion by impure diesel, and alternating vibrations in the engine compartment, the sealing surface of the internal valve core, the nozzle's spray holes expanding, and the aging and leakage of internal sealing components will occur. This may result 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 dimensions, oil circuit interface specifications, and electromagnetic signal matching parameters. During maintenance, the entire injector 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 the Single Product
The slender segmented composite alloy steel integrated cylinder body is rust-proof, resistant to pressure, and does not deform or leak.
The cylinder body is segmented and formed by CNC machining of alloy steel, with surface passivation protection treatment. It is suitable for narrow cylinder head installation space and can withstand the continuous impact of high-pressure fuel for a long time, resisting diesel medium corrosion, high and low temperature temperature differences in the engine compartment, and having less thread slippage and less cracking and leakage of the cylinder body. It maintains the high-pressure sealing performance of the oil circuit for a long time.
Side-mounted integrated inlet and outlet oil dual interfaces, smooth and stable oil circuit pressure track
The side is integrated with an一体成型 inlet and return oil dual pipeline interface， without splicing gaps， reducing the resistance of high-pressure fuel flow， and allowing excess fuel to quickly return and relieve pressure， stabilizing the base oil pressure of the common rail system， eliminating the problem of excessive idle oil pressure 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 for the precise electromagnetic drive mechanism， with sensitive transmission of the electrical control signal， no delay in the reciprocating opening and closing action of the valve core， precise control of the single spray oil volume and spray opening timing， ensuring smooth engine idle and linear acceleration power 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， and is internally equipped with precise multi-micro-hole atomization spray holes. The high-pressure fuel is atomized into fine and uniform particles， fully mixing with oil， reducing carbon accumulation in the cylinder and lowering fuel consumption.
Built-in multi-layer oil-resistant sealing structure， blocking leakage and air backflow
The cylinder body is equipped with multiple specifications of oil-resistant fluorine rubber sealing gaskets， which separate the high and low-pressure oil circuits， preventing high-pressure fuel from leaking out through assembly gaps， and also preventing air from backflowing into the oil circuit after shutdown， avoiding slow oil pressure build-up when starting next time， and ensuring the performance parameters of the entire product are uniform. After assembly， the engine's standard power output can be quickly restored， significantly reducing the time for oil circuit maintenance and debugging. List of Accessories
