Problems solved by technology

[0004] However, when the engine is actually working, the temperature of the intake port wall of the cylinder head is very high, and the intake port wall of the cylinder head will heat the gas, resulting in a decrease in the gas density, thereby reducing the gas mass flow into the cylinder and affecting the engine. volumetric efficiency, which ultimately affects engine performance output

Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] An embodiment of the present invention provides an engine intake system, such as figure 1 As shown, the engine air intake system includes an intake manifold 1 and a cylinder head 2. The intake manifold 1 includes an interpolated air passage 11 and an intake manifold body (not shown in the figure), and the first end of the interpolated air passage 11 It communicates with the air outlet of the intake manifold body, and the second end of the interpolated air passage 11 is sealed and inserted in the air intake passage 21 of the engine cylinder head 2. The material of the interpolated air passage 11 is a material with low thermal conductivity. The gas manifold body is fixed on the outer wall of the cylinder head.

Abstract

The invention discloses an air intake system of an engine. The air intake system of the engine comprises an air intake manifold and an air cylinder cover, wherein the air intake manifold comprises aninternal insertion air channel and an air intake manifold body, a first end of the internal insertion air channel communicates with an air outlet of the air intake manifold body, a second end of the internal insertion air channel is inserted in an air intake channel of the air cylinder cover, the internal insertion air channel is made of a material with low heat conductivity coefficient, and the air intake manifold body is fixed on the outer wall of the air cylinder cover. The internal insertion air channel with low heat conductivity coefficient is used as one part of the air intake channel ofthe air cylinder cover of the engine, as the heat conductivity coefficient of the internal insertion air channel, the heating effect of the air intake channel of the air cylinder cover of the engineon air can be reduced, and the volume coefficient of the engine can be enhanced.

Description

technical field [0001] The invention belongs to the technical field of engines, in particular to an engine intake system. Background technique [0002] As my country's fuel consumption and emission regulations become increasingly strict, improving the output performance of the engine has become the focus of the research of major automobile manufacturers. Among the many means to improve the output performance of the engine, improving the volumetric efficiency of the engine is one of the most important means. Generally speaking, one of the most important factors affecting the volumetric efficiency of the engine is the temperature of the gas at the intake valve of the cylinder. Generally, the higher the gas temperature at the intake valve and the lower the gas density, the lower the gas mass flow into the cylinder and the less oxygen into the cylinder. [0003] The engine air intake system in the related art filters and cleans the gas through the air filter, and introduces it ...
