Description
Product Overview
The injector is assembled onto the engine cylinder head and receives signals from the electronic control unit to precisely control the timing and amount of high-pressure fuel injection, ensuring complete atomization and combustion of the fuel. Under long-term short-distance construction work, alternating hot and cold conditions in the engine compartment, and diesel fuel contaminated with impurities, internal valve core seals may wear out, sealing components may age, and electromagnetic valves may respond slowly, resulting in imbalance in single-cylinder power output, power loss, fuel leakage into the engine oil to dilute the lubricating medium, and continuous alarm of the fault indicator. This product is an integrated finished injector, with standardized dimensions for the external diameter for installation, return oil interface, and electronic control plug. The injection curve is uniformly calibrated at the factory, and maintenance and replacement do not require additional pressure adjustment or debugging. It is suitable for the maintenance of small engineering equipment and light diesel power units.
Core Advantages of the Single Product
Extended segmented black alloy steel valve body, resistant to vibration and high temperature
Multi-segment extended integrated black passivated alloy steel housing, with an increased outer wall for a stronger structure, suitable for installation on shallow cylinder heads, able to withstand continuous vibration and high temperatures in the engine compartment, and not prone to deformation or cracking under long-term high-pressure conditions, preventing valve body oil leakage and pressure relief.
Top waterproof insulated electronic control plug, stable signal transmission and resistance to oxidation
Integrated sealed electronic control plug terminals, with gold-plated conductive contacts, an outer layer of insulation and dust-proof cover, isolating diesel oil, gas, and water vapor corrosion, with no delay in electronic control signals, smooth switching between pre-injection and main injection, eliminating acceleration power surges and intermittent cylinder missfires.
Sideways independent return oil branch pipe, rapid pressure release and stable track pressure
Sideways small low-pressure return oil channel, capable of quickly discharging excess return fuel, releasing residual pressure in the oil circuit, eliminating oil circuit air resistance, improving difficulties in starting the cold engine multiple times and unstable idle speed in dusty and impure diesel environments.
Front end copper ring-shaped sealing gasket, layer-by-layer isolation of high-temperature gas leakage
Integrated copper sealing ring at the nozzle root, assembled to closely fit the cylinder head installation hole, layer-by-layer blocking of high-temperature gas in the combustion chamber from rising and outward leakage of high-pressure fuel, preventing the engine oil from being diluted by the fuel.
Full port transparent dust-proof plugs, all-round protection of the precise structure
Three places on the product, including the electronic control plug, return oil branch pipe, and nozzle tip, are equipped with transparent plastic protective plugs. They are used to seal fine channels during storage, cross-border transportation, disassembly and maintenance, blocking dust from scratching the needle valve sealing surface and blocking the nozzle holes.
Complete flow calibration at the factory for the entire machine, quick restoration of power after replacement
The product is completed with high and low-pressure full-condition injection flow, opening pressure, and atomization effect detection at the factory. The parameters of the same batch of injectors are highly consistent, and after replacement, the idle speed is stable, the power output is linear, and the maintenance and debugging time is significantly reduced.
Application Scenarios
Suitable for small mining excavators, light wheeled loaders, and fixed small diesel generators equipped with high-pressure common rail fuel supply systems, suitable for light-load continuous operation in construction sites, outdoor alternating high and low temperatures, and light-duty electrically controlled common rail diesel engines in dusty and impure diesel environments for injector replacement.
