[0002] The load of the natural gas engine is realized by controlling the intake air volume with the throttle valve. Most of the current natural gas engines use a single-point injection pre-mixed route, that is, the mixture of air and gas is in the intake manifold. When the engine fails, it is easy to cause backfire. The mixed gas burns in the intake pipe, and the high-temperature and high-pressure gas will impact the throttle valve upstream of the intake pipe. If the throttle plate is not strong enough, the butterfly plate will be deformed or stuck, and the air volume of the engine will not be controlled, resulting in vehicle power loss. , affecting driving safety

The invention discloses a device for simulating engine tempering generation. The device comprises an air storage tank, a first pipeline, a combustion chamber, a first pressure and temperature sensor, a first nozzle, a CNG storage tank, a second pipeline, a second pressure and temperature sensor, a second nozzle, a third pressure and temperature sensor, a spark plug, a throttle valve and an ECU. The air storage tank is used for storing air; one end of the first pipeline is connected with an outlet of the air storage tank; an air inlet of the combustion chamber is connected with the other end of the first pipeline; the first pressure and temperature sensor is arranged at an outlet of the air storage tank and used for monitoring the pressure and temperature in the air storage tank in real time; and the first nozzle is arranged in the first pipeline, and the first nozzle is used for spraying air to the combustion chamber. The device for simulating engine tempering generation is simple and reasonable in structure, the size and the speed of combustion pressure can be controlled, and tempering intensities with different requirements can be simulated.
Description
technical field [0001] The invention relates to the technical field of power machinery, in particular to a device for simulating engine backfire generation. Background technique [0002] The load of the natural gas engine is realized by controlling the intake air volume with the throttle valve. Most of the current natural gas engines use a single-point injection pre-mixed route, that is, the mixture of air and gas is in the intake manifold. When the engine fails, it is easy to cause backfire. The mixed gas burns in the intake pipe, and the high-temperature and high-pressure gas will impact the throttle valve upstream of the intake pipe. If the throttle plate is not strong enough, the butterfly plate will be deformed or stuck, and the air volume of the engine will not be controlled, resulting in vehicle power loss. , affecting driving safety. In order to avoid the above problems, the anti-tempering ability of the throttle valve must be assessed to ensure that when the engine...
