Problems solved by technology

[0003] The main purpose of the present invention is to provide an engine cylinder head and a cylinder, aiming at solving the problem that in the cooling process of the existing engine cylinder head, the coolant flows in a single direction, and successively contacts with multiple exhaust pipes in thermal contact, causing the last exhaust pipe to be exhausted. Technical problem with poor cooling effect

Abstract

The engine cylinder cover comprises a shell, a plurality of exhaust pipelines and a cooling water jacket, the exhaust pipelines are arranged on the shell and arranged side by side in the length direction of the shell, and the cooling water jacket is arranged on the shell and makes thermal contact with the exhaust pipelines so as to dissipate heat of the exhaust pipelines. The cooling water jacket is provided with a water outlet and a plurality of water inlets, and the water inlets are arranged at intervals in the length direction of the shell. According to the scheme, the cooling water jacket is provided with the multiple water inlets, and the multiple water inlets are formed in the length direction of the shell at intervals, so that the problem that the cooling effect of the exhaust pipeline located behind the cooling liquid flowing direction is poor due to the fact that the temperature of the cooling liquid close to the water outlets is high due to the single flowing direction of the cooling liquid is solved. Specifically, in the scheme, the temperatures of the cooling liquid input from the water inlets near the exhaust pipelines are consistent and relatively low, so that heat dissipation of the exhaust pipelines is uniform, the heat dissipation effect of the exhaust pipelines is improved, and the service life of the engine is prolonged.

Description

technical field [0001] The invention relates to the technical field of engine equipment, in particular to an engine cylinder head and a cylinder. Background technique [0002] When the vehicle is running, the engine will generate high temperature due to continuous operation, so it needs to be cooled and dissipated to avoid damage to related components due to the high temperature generated. At present, during the cooling process of the cylinder head of the engine, the coolant flows in a single direction and is in thermal contact with multiple exhaust pipes in turn, resulting in poor cooling effect of the last exhaust pipe, so that the temperature inside the cylinder is still high, and the temperature of its related components is also low. High, the waste heat generated by combustion in the combustion chamber is dissipated through the surface of the cylinder, and the heat dissipation effect is not good, which affects the output power of the engine.
