The invention relates to the technical field of automobile equipment, and discloses a fuel injection nozzle for an automobile engine. An electromagnetic coil is fixedly sleeved in the middle of the inner cavity of the body, an oil hole is opened in the body, a return spring is sleeved in the middle of the oil hole, and a valve body is fixedly installed on the bottom surface of the return spring. The fuel injector for automobile engine is matched with the tapered hole through the inclined surface of the separating sleeve, and the connecting part of the oil passage on the tapered hole is above the separating sleeve, so that the valve body attracts and lifts the valve body after the electromagnetic coil is energized and drives at the same time. The separation sleeve moves up, before the shaft needle is separated from the nozzle, the separation sleeve is sealed with the cone hole, the shaft needle continues to move upward, and the gasoline under the separation sleeve is squeezed to pressurize, so that when the shaft needle is separated from the open nozzle, the pressure of the gasoline sprayed out Larger, the sprayed gasoline has better atomization effect and full combustion.
Description
technical field [0001] The invention relates to the technical field of automobile equipment, in particular to a fuel injection nozzle for an automobile engine. Background technique [0002] The engine fuel injector is a key component of the EFI engine. Its working condition will directly affect the performance of the engine. After the car runs for a period of time, certain deposits will be formed in the fuel system. It is directly related that the gas oil contains unstable components such as dust, impurities, and colloid, which react at a certain temperature to form resinous viscous substances. These viscous substances form carbon deposits on the fuel injection nozzles, and the carbon deposits cause The gasoline ejected from the fuel port cannot spread well, which in turn leads to insufficient combustion of the gasoline, which affects the efficiency of the engine. [0003] At the same time, the fuel injector relies on the magnetic force of the electromagnetic coil to attrac...
