发动机进气系统
摘要：
本发明公开了一种发动机进气系统，所述发动机进气系统包括进气歧管和气缸盖，所述进气歧管包括内插气道及进气歧管本体，所述内插气道的第一端与所述进气歧管本体的出气口连通，所述内插气道的第二端密封插装在所述气缸盖的进气道内，所述内插气道的材料为导热系数低的材料，所述进气歧管本体固定在所述气缸盖的外壁上。本发明中通过使用导热系数低的内插气道作为发动机气缸盖进气道的一部分，由于内插气道的导热系数低，这样便可降低发动机气缸盖进气道对气体的加热效应，进而提升发动机容积效率。
摘要（英）：

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.
