Description
Product Overview
The electronically controlled common rail injector receives 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 in diesel washing, continuous vibration under high and low temperatures, the wear of the internal valve core sealing surface, deformation of the nozzle spray holes, aging and leakage of the sealing parts, will cause unbalanced fuel supply for a single cylinder, pressure loss in the high-pressure oil circuit, decrease in engine power, and increase in 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 injector can be directly replaced, eliminating the need for individual adjustment of internal components, and is suitable for maintenance of light trucks, pickups, medium-sized construction machinery, and diesel generator sets.
Core advantages of this 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 the impact of high-pressure fuel, resisting diesel corrosion and temperature changes, the cylinder body is not prone to cracking, the threads are not prone to slippage, and can maintain the sealing performance of the high-pressure oil circuit stably for a long time.
Side-mounted integrated return oil interface, smooth and stable oil flow pressure track
The side-mounted integrated return oil connector is formed by one-piece molding, without splicing gaps, reducing the resistance of fuel flow, 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 fuel injection per time.
Top-mounted precision electromagnetic driving component, rapid and no-delay signal response
The upper end integrates the electromagnetic actuator, with a compact and stable structure, sensitive to electrical control signals, timely response of the valve core opening and closing action, precisely controlling the fuel injection volume and timing, ensuring smooth idle operation of the engine, and smooth acceleration power output.
Front-end precision atomizing nozzle, uniform atomization, full combustion
The nozzle is precisely ground and processed, with fine atomization particles, full oil-gas mixture, effectively reducing the generation of carbon deposits in the cylinder, optimizing fuel consumption levels, and reducing exhaust emissions.
Multi-layer oil-resistant sealing structure, bidirectional anti-leakage, anti-airflow back-suction
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 back-suction into the oil circuit after shutdown, solving the problems of starting oil circuit intake and slow oil pump pressure building-up.
The entire machine is tested in a test bench before leaving the factory, and installation does not require secondary calibration.
Each injector independently completes electromagnetic response, high-pressure pressure retention, atomization effect, and injection flow detection calibration, with unified performance parameters. After assembly, it quickly restores the original power performance of the engine, shortening the time for oil circuit maintenance and debugging. List of Accessories
