The invention discloses an anti-clogging diesel nozzle internally provided with double grinding teeth. The anti-clogging diesel nozzle comprises a needle valve and a needle valve shell, wherein the needle valve is arranged in the needle valve shell; a liquid guide cavity, a pressure storage cavity, a pressure injection cavity and a nozzle are arranged in the needle valve; the liquid guide cavity is arranged at the front end inside the needle valve shell; the pressure storage cavity is connected to the rear end of the liquid guide cavity; turntable grinding teeth are arranged in the pressure storage cavity; the pressure injection cavity is arranged at the rear end of the pressure storage cavity; turntable grinding teeth are also arranged in the pressure injection cavity; and the nozzle is connected to the rear end of the pressure injection cavity. In such a way, the condition of clogging caused by diesel oil greasing can be avoided because the turntable grinding teeth are arranged inside the pressure storage cavity and the pressure injection cavity of the nozzle; and the turntable grinding teeth can be driven by pressure to rotate after the diesel oil enters from liquid inlets of the pressure storage cavity and the pressure injection cavity, and furthermore the thick diesel oil is mixed, so that the oil injection efficiency of the nozzle is increased.
Description
technical field [0001] The invention relates to the field of fuel injectors, in particular to an anti-clogging diesel engine fuel injector with built-in double grinding teeth. Background technique [0002] The fuel injector used in automobiles is actually a simple solenoid valve. When the solenoid coil is energized, suction is generated, the needle valve is sucked up, the nozzle hole is opened, and the fuel passes through the annular space between the pin of the needle valve head and the nozzle hole. The gap is sprayed at high speed to form a mist, which is conducive to full combustion. In the past, the fuel injectors used in diesel engines were mechanically controlled, and the mechanical diesel nozzles worked by controlling precision couplings (needle valves, needle valve bodies). The coupling part of the nozzle is one of the three precision coupling parts of the traditional diesel engine, the three precision coupling parts: plunger, plunger sleeve, needle valve, needle va...
