Problems solved by technology

The X-shaped water channel is located in the middle of the four valve seats of the cylinder head. The water flow can only cool the heat transferred to the X-shaped water channel from the high-temperature seat area. There is no direct contact, and the cooling effect is very general.

Abstract

The invention discloses a cylinder cover, which comprises a cylinder cover body, a water inlet, an upper water jacket, a lower water jacket, a water-stop sheet, a water outlet and a seat ring. The water inlet is formed in the upper portion of the cylinder cover body. The upper water jacket is fixed to the top end of the interior of one side of the cylinder cover body and connected with the water inlet. The lower water jacket is fixed to the bottom inside one side of the cylinder cover body. The water-stop sheet is arranged at the interval between the upper water jacket and the lower water jacket. The water outlet is formed in the lower portion of the cylinder cover body. The seat ring is arranged at the bottom of the cylinder cover body, wherein a round hole is formed in the middle of the water-stop sheet; and the upper water jacket is communicated with the lower water jacket through the round hole. Therefore, the cylinder cover disclosed by the invention is simple and reasonable in structure and good in cooling effect; performance reduction caused by overheating of all parts of an engine combustion system can be prevented; and the performance of an engine is improved.

Description

technical field [0001] The invention relates to the technical field of diesel engines, in particular to a cylinder head. Background technique [0002] The cylinder head is a key part of the engine and an indispensable part of the engine combustion chamber. Clean air enters the combustion chamber through the cylinder head and mixes with fuel for compression ignition. During combustion, the cylinder head has to withstand the high temperature and high pressure brought by combustion, so the cooling of the cylinder head is particularly important. The water-cooled engine takes away the heat generated by the flow of liquid. If the cooling effect is not good, the cylinder head is extremely prone to cracking, air leakage, water leakage, oil leakage, etc., resulting in a decrease in engine performance or even damage to the engine. [0003] The existing cylinder head (CN102797583A) adopts a water-cooling method, and the water flow field is bottom-up, and the incoming water is subjecte...
