Air filter gas inlet pipeline arrangement method and structure for improving engine power performance

Abstract

The invention provides an air filter gas inlet pipeline arrangement method and structure for improving engine power performance. An air filter inlet pipeline comprises a gas inlet pipe, a decoupling corrugated tube and a gas inlet assembly, wherein the gas inlet assembly comprises an overhead wind baffle and a gas inlet bent pipe, a gas inlet is formed in the overhead wind baffle, the gas inlet bent pipe is connected with the gas inlet from the portion above the overhead wind baffle, the overhead wind baffle is arranged in the position, close to the front portion of a vehicle, of the top portion of a condenser so that the gas inlet can be located in the top face of an air inlet cabin formed by the condenser, a front bumper, the overhead wind baffle and side wind baffles, and low-temperature air can be directly sucked. The air filter gas inlet pipeline arrangement structure is simple and convenient to install, and the method and the structure are beneficial to lowering the gas inlet temperature, reducing gas inlet vortexes and improving the engine power performance.

Description

technical field [0001] The invention relates to an automobile air filter. Background technique [0002] At present, the air intake of passenger car engine air filters used in the market is mostly located inside the engine compartment composed of cooling modules such as the engine, condenser, engine water tank and fan. The cooling system cools the engine and at the same time After the high-temperature air in the engine compartment is cooled, the air directly enters the air filter through the air intake. [0003] In this case, due to the high temperature of the engine compartment, the cooling system has a limited cooling effect on the high-temperature air in the engine compartment, so the temperature of the air entering the engine through the air filter is usually 20°C~40°C higher than the ambient temperature, making the air enter the engine compartment. The reduction of the air volume reduces the power of the engine; at the same time, the air entering the air filter is often...

Problems solved by technology

[0003] In this case, due to the high temperature of the engine compartment, the cooling system has a limited cooling effect on the high-temperature air in the engine compartment, so the temperature of the air entering the engine through the air filter is usually 20°C~40°C higher than the ambient temperature, making the air enter the engine compartment. The air volume is reduced, which reduces the power of the engine; at the same time, the air entering the air filter is often in a negative pressure area, and a vortex is often generated at the air filter inlet, which makes the air intake insufficient, resulting in a further drop in engine power
