Abstract

The invention discloses a high-strength air cylinder cover with a heat dissipation function. The high-strength air cylinder cover comprises an air cylinder cover top plate, an air cylinder cover bottom surface, exhaust ports, valve lug sets and an oil passage. An oil sprayer hole is formed in the center of the air cylinder cover top plate; the exhaust ports are formed to correspond to a pluralityof air cylinders and configured to gather outlets of the exhaust ports into the air cylinder cover; the exhaust ports are provided with push rod holes; protruding side walls are arranged on the peripheries of the top faces of the valve lug sets correspondingly; a plurality of reinforcing ribs are arranged between the side wall of each valve lug set and the air cylinder cover top plate; and the oilpassage is positioned in the inner side, in the arranging direction of the air cylinders, of the air cylinder cover. According to the air cylinder cover, the temperature of lubricating oil is effectively decreased, the strength and performance of the air cylinder cover are improved, the appearance is compact and attractive, and the reinforcing ribs are additionally arranged on the air cylinder cover, so that the local strength of all parts of the air cylinder cover is enhanced.

Description

technical field [0001] The invention belongs to the technical field of cylinder equipment, in particular to a high-strength cylinder head with heat dissipation. Background technique [0002] The cylinder head of the current multi-cylinder engine is a flat plate type, and there is no lubricating oil return channel on the top plate. The lubricating oil on the top plate returns to the crankcase through the push rod hole on the exhaust side, which brings problems because The temperature of the push rod hole on the exhaust side is very high. When the lubricating oil flows through, it will be heated by high temperature, and the temperature of the lubricating oil will rise, which will accelerate the aging of the lubricating oil. Reduced lifespan. Moreover, when the cylinder is depressurized, the thermal load on the cylinder head increases, and the range of the fire seal ring on the bottom surface of the cylinder head is significantly sunken upwards under the action of the combusti...
