Abstract

The invention provides a cylinder cover of a water-cooled engine. A water jacket is arranged on the cylinder cover and comprises an upper water jacket and a lower water jacket which are separated by a partition plate, the lower water jacket is close to a cylinder block of the water-cooled engine, a water inlet hole is formed in the upper water jacket, a water outlet hole is formed in the lower water jacket, a water passing channel communicated with the upper water jacket and the lower water jacket is arranged on the partition plate and positioned in a noise bridge area of the cylinder cover, and the circulation area of the upper water jacket, the circulation area of the lower water jacket and the circulation area of the water passing channel are sequentially decreased. According to the cylinder cover of the water-cooled engine, the flow speed and the flow of cooling water of the water jacket are reasonably distributed to different cooling areas of the cylinder cover, so that heat load is furthest taken away, and cooling effects are improved. The invention further provides the water-cooled engine which comprises a plurality of cylinders and cylinder covers arranged on the cylinders.

Description

technical field [0001] The present invention relates to the technical field of water-cooled engine manufacturing, more specifically, to a cylinder head of a water-cooled engine, and also relates to a water-cooled engine with the above-mentioned cylinder head. Background technique [0002] With the continuous development of modern water-cooled engine technology, the strengthening degree of water-cooled engines continues to increase, especially high-power diesel engines that are developing towards high explosion pressure. However, when a high-explosion pressure high-power diesel engine is working, it will cause a large heat load on the cylinder head, especially in the nose bridge area where the cold and heat exchange is the most intense, that is, the heat load is high. In order to reduce the failure rate, it is necessary to The cooling water jacket is designed on the cylinder head for particularly sufficient cooling of the cylinder head. [0003] When the water-cooled engine ...
