Description
Product Overview
The electronically controlled common rail injector receives 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 spraying it into the cylinder to complete combustion and power generation. Under long-term load operation, impurities from diesel fuel erosion, continuous vibration under high and low temperatures, the internal valve core sealing surface wear, nozzle spray hole deformation, and aging and leakage of sealing components can cause unbalanced fuel supply for a single cylinder, high-pressure oil circuit pressure relief, engine power reduction, and increased black smoke emissions from the exhaust. This product is standardized in installation dimensions, oil circuit interface specifications, and electromagnetic signal parameters. During maintenance, the entire set of injectors can be directly replaced, eliminating the need for individual adjustment of internal components, and is suitable for maintenance of medium-sized freight vehicles, medium-sized construction machinery, and diesel generator sets.
Core advantages of the product
Thickened segmented alloy steel cylinder body, high strength, pressure resistance, and anti-deformation, not prone to oil leakage
The cylinder body is precisely machined by CNC from thickened alloy steel, with surface passivation for rust prevention, suitable for installation on the cylinder head of medium-sized engines, capable of long-term withstanding high-pressure fuel impact, resisting diesel corrosion and temperature changes, the cylinder body is not prone to cracking, and the threads are not prone to slippage, maintaining stable high-pressure oil circuit sealing for a long time.
Side-mounted integrated inlet and outlet return oil interface, smooth oil flow and stable track pressure
The side edge integrates an integrated and formed inlet and return oil pipeline interface, without splicing gaps to reduce fuel flow resistance, excess fuel quickly returns and depressurizes, stabilizing the common rail system oil pressure, improving the phenomenon of cylinder carbon deposition and black smoke emissions caused by excessive single-time fuel injection.
Top precision electromagnetic drive component, rapid and no-delay signal response
Pre-assembled on the top end for the electromagnetic actuator, the electrical control signal is sensitive, the valve core opening and closing action responds promptly, precisely controlling the fuel injection volume and timing, ensuring smooth idle engine operation and smooth acceleration power output.
Front-end multi-level stepped limit nozzle, precise positioning and uniform atomization
The front-end stepped limit structure automatically aligns and clamps during assembly without deviation; paired with multiple micro-hole precision spray holes, the high-pressure fuel is atomized finely, the oil and gas are fully mixed, reducing the generation of cylinder carbon deposits, optimizing fuel consumption levels.
Multi-layer oil-resistant sealing structure, bidirectional anti-leakage, anti-airflow backflow
The cylinder body is equipped with multiple specifications of fluorine rubber oil-resistant sealing rings, layering to isolate high and low pressure oil circuits, preventing fuel leakage outward; at the same time, preventing air backflow into the oil circuit after shutdown, solving the problem of starting oil circuit intake and slow oil pump pressure building.
Complete itemized factory test for the entire machine, no need for secondary adjustment during installation
Each injector independently completes electromagnetic response, high-pressure pressure retention, atomization effect, and injection flow detection calibration, with unified performance parameters, quickly restoring the original engine power performance after assembly, shortening the time for oil circuit maintenance and debugging.
