Abstract

The invention relates to an engine cylinder cover air channel structure. The engine cylinder cover air channel structure corresponding to a quadruple-cylinder engine consists of four groups of same air channels, wherein each group of air channels comprises one air inlet channel and an exhaust channel. Each air inlet channel consists of one main air inlet channel located on the outer side of a cylinder cover and two air inlet branch channels. Each exhaust channel consists of a main exhaust channel located on the outer side of the cylinder cover and two exhaust branch channels. An inlet of the main air inlet channel is similar-calabash-shaped. An outlet of the main exhaust channel is similarly oval. The two air inlet branch channels and the two exhaust branch channels are symmetrically distributed on two sides of a central plane of the air channels.

Description

technical field [0001] The invention belongs to the field of engines, and specifically refers to an engine cylinder head air channel structure. Background technique [0002] As the key component of the engine, the cylinder head has a decisive effect on the level of engine power and torque during the working process, and the smoothness of the exhaust also plays a decisive role on the size of the emission value and the level of temperature. . If the engine is not designed properly, the power and torque will never reach the design target value, and the exhaust back pressure and high temperature will cause problems such as poor exhaust, broken exhaust manifold, and reduced engine power and torque. [0003] The intake port of the traditional engine cylinder head adopts an elliptical design, and the smallest cross section is mostly designed at the end of the intake port, that is, the position of the intake valve seat hole; the exhaust port is mostly designed in a circular shape, ...
