Problems solved by technology

Cylinder heads with traditional structures cannot meet the requirements of future high-power-density, highly-strengthened light-duty engines in terms of performance and reliability
[0003] The intake port of the four-valve cylinder head of the current light engine generally adopts a combined intake port structure, with one intake port 1 for each cylinder, such as figure 1 As shown, in the intake process, there will be mutual interference between the two intake channels, which will affect the intake efficiency; at present, the cylinder head push rod hole 3 of the side camshaft is generally located on the side of the exhaust port 2, and the lubricating oi

Abstract

The invention relates to the technical field of diesel cylinders and discloses a four-valve cylinder cover for a lightweight engine. Push rod holes and water jackets are arranged in the cylinder cover; air inlet channels are formed in one side of the cylinder cover; air exhaust channels are formed in the other side of the cylinder cover; the interior of the cylinder cover is divided into four partition cylinders; the water jackets include an upper water jacket and lower water jackets; the upper water jacket is arranged on the upper side in the cylinder cover; the lower water jackets are arranged on the lower side in the cylinder cover; a water channeling hole for communicating the upper water jacket and the lower water jackets is formed between the upper water jacket and the lower water jackets; two adjacent partition cylinders share one air inlet channel; and the push rod holes are arranged close to the corresponding air inlet channels. The four-valve cylinder cover can prevent intake flows from mutually interfering so as to improve the air inlet efficiency, can prevent the ageing problem of lubricating oil and can also improve the cooling efficiency.
