Abstract

The invention discloses an engine air cylinder cover. The engine air cylinder cover comprises an air cylinder cover and a sealing cushion plate. Heat dissipation grooves are formed in the front side, back side, left side and right side of the air cylinder cover at equal intervals. Four air cylinder seats are transversely and uniformly arranged in the center of the bottom of the air cylinder cover in the horizontal direction. A plurality of fixing screw holes are formed in the bottom of the air cylinder cover. A plurality of limiting columns are fixedly connected to the bottom of the air cylinder cover. Limiting holes are formed in positions, corresponding to the limiting columns, of the surface of the sealing cushion plate. The limiting columns are fixedly inserted into the limiting holes. First through holes are formed in positions, corresponding to the air cylinder seats, of the bottom of the sealing cushion plate. Second through holes are formed in positions, corresponding to the fixing screw holes, of the bottom of the sealing cushion plate. The shape and structure of the second through holes are the same as that of the fixing screw holes. By means of the engine air cylinder cover, heat in the air cylinder cover is prevented from being accumulated in a centralized manner and can be quickly guided outwards through a heat conduction silica gel sheet.

Description

technical field [0001] The invention relates to the technical field of engine parts, in particular to an engine cylinder head. Background technique [0002] The engine cylinder head is generally made of cast iron or aluminum alloy. It is the installation base of the valve mechanism and the sealing cover of the cylinder. The cylinder head machine for cars is mostly made of aluminum alloy cylinder head. The engine cylinder head can withstand gas force and The mechanical load caused by tightening the cylinder head bolts can also withstand the high thermal load caused by contact with high-temperature gas. In order to ensure a good seal of the cylinder, the cylinder head can neither be damaged nor deformed, so the cylinder head should have sufficient Strength and rigidity, the purpose is to make the temperature distribution of the cylinder head as uniform as possible, to avoid thermal cracks between the intake and exhaust valve seats. [0003] With the continuous development of ...
