Turbo supercharged engine intake manifold with flow guiding structures

Abstract

The invention relates to a turbo supercharged engine intake manifold with flow guiding structures. The turbo supercharged engine intake manifold comprises an upper manifold sheet, an intercooler and a lower manifold sheet. The intercooler is connected with the upper manifold sheet and the lower manifold sheet. The upper manifold sheet and the lower manifold sheet are connected. The flow guiding structures are arranged on the inner wall of the upper manifold sheet and the inner wall of the lower manifold sheet. Compared with the prior art, the turbo supercharged engine intake manifold has the beneficial effects of being high in heat exchange efficiency, simple in structure, small in size and the like.

Description

technical field [0001] The invention relates to a turbocharged engine intake manifold, in particular to a turbocharged engine intake manifold with a guide structure. Background technique [0002] In the intake system of a turbocharged engine, after the air is compressed by the supercharger, the temperature will rise and become hot air, and the air with too high temperature will affect the engine in two aspects: on the one hand, the volume of high-temperature gas Larger, which means that the intake air volume is reduced; on the other hand, high-temperature gas is not good for the combustion of the engine, the power will be reduced, and the emissions will also be worse. Therefore, an intercooler is required to reduce the temperature of the air entering the engine. [0003] When a boosted engine is running, hot air enters the manifold and passes through the intercooler into the engine cylinders. Usually, affected by the structure of the intake manifold itself, the gas flow fi...

Problems solved by technology

[0004] Arranging a guide structure inside the intake manifold can optimize the distribution of the flow field in the manifold, thereby improving the performance of the engine. For example, Chinese Patent Publication No. CN 202883178U discloses an intake manifold with a guide structure, including The inlet of the manifold, the plenum chamber and four air passages, the inlet of the manifold and the four air passages are connected with the plenum chamber, the intercooler is installed in the plenum chamber, and the manifold between the inlet of the manifold and the intercooler There is a diversion structure on the wall, which allows the airflow inside the intake manifold to pass through the intercooler more evenly, ensuring that the intercooler has a high heat exchange efficiency, but its diversion effect is lacking. not very full

In addition, if the deflector structure is too complicated, for example, a deflector or an embedded deflector structure, it will increase the weight of the product and the complexity of manufacturing, and sometimes cause excessive resistance to affect the intake air volume
