Exhaust gas pressure boost type automobile engine air intake filter device

Abstract

The invention discloses an exhaust gas pressure boost type automobile engine air intake filter device which comprises a circular pipe body. The inner wall of the pipe body is fixedly provided with a middle plate penetrating through the axis, a middle shaft is arranged at the axis of the pipe body, the middle shaft is rotatably connected into the middle plate, a plurality of inclined blades are fixed to the circumferential side wall of the middle shaft, the multiple blades are jointly and fixedly connected with a fixing ring, the inner wall of the pipe body is provided with an annular groove, the fixing ring is slidably connected into the annular groove, and filter nets are fixedly connected to the two sides of the fixing ring. The exhaust gas pressure boost type automobile engine air intake filter device has the advantages that when an engine works, due to the action of exhaust gas generated by combustion and heat release, the amount of exhaust gas discharged per unit time is much larger than the intake amount of the engine, the discharged exhaust gas has obvious kinetic energy, exhaust gas generated by the engine can obviously drive a rotating shaft and the blades to rotate, the generated rotational speed enables the blades in an air suction pipe to generate sufficient airflow, and the supercharging effect on the engine is formed.

Description

technical field [0001] The invention relates to the technical field of engine intake filter, in particular to an exhaust gas booster type automotive engine intake filter device. Background technique [0002] The engine is the most important part of the car. During the working process of the engine, when the intake valve of the cylinder is opened, it will generate negative pressure and inhale outward, but the negative pressure inhalation cannot inhale enough gas, so it is difficult to ensure the combustion of fuel in the cylinder Sufficiently, the engine supercharging methods in the prior art include two kinds of turbocharging and supercharging, and the effect of supercharging is better than that of turbocharging. Too much is pressed into the engine, and the engine must inhale the clean gas filtered by the air filter. The existing supercharging method does not have the effect of cleaning the air filter part of the engine, resulting in a shorter service life of the engine air ...

[0002] The engine is the most important part of the car. During the working process of the engine, when the intake valve of the cylinder is opened, it will generate negative pressure and inhale outward, but the negative pressure inhalation cannot inhale enough gas, so it is difficult to ensure the combustion of fuel in the cylinder Sufficiently, the engine supercharging methods in the prior art include two kinds of turbocharging and supercharging, and the effect of supercharging is better than that of turbocharging. Too much is pressed into the engine, and the engine must inhale the clean gas filtered by the air filter. The existing supercharging method does not have the effect of cleaning the air filter part of the engine, resulting in a shorter service life of the engine air filter, especially When the vehicle is driven in a harsh environment, the life of the vehicle air filter will be greatly shortened. If the air filter cannot be cleaned or replaced in time, the vehicle will cause serious damage
