Description
Product Overview
392-0217 is a mechanical pressurization + electric control adjustment composite fuel injection assembly. It relies on the large spring at the rear to provide the basic injection pressure, and the side electromagnetic module precisely controls the opening and closing of the fuel injection and the fuel injection volume. It is suitable for diesel power equipment with high power and continuous full-load operation. When the old fuel injector has problems such as weak spring, delayed response of the electromagnetic valve, oil leakage in the valve body, and poor atomization, the entire set can be replaced to repair all fuel supply faults at once. It is suitable for deep maintenance of mining and large-scale engineering equipment.
Unique Core Features of the Single Product
Extruded thick heavy-duty spiral spring, long-lasting fatigue resistance and stable rebound
The rear is equipped with a large-sized thick-pressure-bearing spring, with sufficient steel toughness. During the equipment's all-weather continuous operation, there will be no weak spring compression, and the stable injection pre-pressure will be maintained throughout, eliminating the problems of fuel supply lag and insufficient injection force.
Side-mounted independent white electromagnetic drive module, signal isolation and anti-interference
The side-mounted split electromagnetic drive unit has a white insulated shell that isolates the cylinder body's high temperature and electromagnetic interference. The double-pinch contacts transmit signals stably, and there will be no contact breakage in the case of vibration and shock, avoiding random engine cylinder misfire error.
Multi-stage segmented metal valve body, multi-layer ring-shaped sealing to prevent leakage
The main valve body is segmented and turned to form, and each section is paired with an independent oil-resistant sealing ring. The pressure of the high-pressure fuel is evenly shared in each layer, and the sealing parts are less likely to age under long-term high-temperature and high-pressure conditions. There will be no oil leakage or carbon accumulation in the valve body joint gap.
Conical elongated precision nozzle, constant spray angle with less carbon deposits
The front end has a gradually constricted conical nozzle, with evenly distributed micro-holes, and the fuel injection covers the combustion chamber area evenly, ensuring complete combustion, significantly reducing the speed of carbon deposition at the nozzle head, and extending the cleaning and maintenance cycle of the fuel injector.
Integrated molded positioning mounting ears, secure assembly and no offset
The side of the body is equipped with a cast positioning protrusion, which is inserted into the cylinder body slot for precise positioning during installation. When the locking piece is locked, there will be no shaking or offset. In heavy-load and vibration conditions, the fuel injection position remains stable, and no injection offset will occur. Applicable scenarios
Suitable for high-power diesel power units, mainly used in large mining equipment, heavy loaders, large excavators, fixed high-power generator sets, and suitable for the oil supply system replacement of equipment for 24-hour continuous full-load operation in mining areas and outdoor construction sites.
