Engine cylinder cover

Abstract

The invention relates to a cylinder head of an engine, which is characterized in that a cylinder head body is respectively provided with water outlets, water inlets, an exhaust passage, an intake passage and cooling water chambers, the water inlets are arranged along one side of the exhaust passage and one side of the intake passage, the water outlets are arranged on one end of the cylinder head body, and an inlet valve base is connected with an exhaust valve base, wherein insides of the cooling water chambers at the plurality of water inlets are respectively provided with a first guiding plate, a second guiding plate, a third guiding plate and a fourth guiding plate, upper parts of the first guiding plate, the second guiding plate, the third guiding plate and the fourth guiding plate are connected respectively with top surfaces of the cooling water chambers, the sides of the first guiding plate, the second guiding plate, the third guiding plate and the fourth guiding plate are respectively connected with the sides of the cooling water chambers and bolt hole bases. The cylinder head of the engine compels the cooling water to guide to a nose bridge area through a guiding function of the guiding plates to guarantee sufficient water amount and flow velocity of the nose bridge area to pass, thereby improving cooling effect of the cylinder head and achieving an aim of equalizing cooling.

Description

technical field [0001] The invention relates to a cylinder head of an engine, in particular to a cylinder head of a water-cooled engine, and belongs to the technical field of water flow control of an engine cooling system. Background technique [0002] The cylinder head is the casting with the most complex structure in the engine. It is arranged with intake passage, exhaust passage, intake valve seat, exhaust valve seat, bolt hole seat, cooling water cavity, water inlet, water outlet, fuel injection nozzle hole and Grease holes etc. During the working process, the cylinder head bears the high pressure and high temperature of the combustion gas. Due to the complex structure of the cylinder head, the wall temperature of each part of the cylinder head is uneven, especially in the nose bridge area between the intake and exhaust valves. Due to the narrow passage, complex structure, large water flow resistance, insufficient water cooling, serious poor heat dissipation, A large t...

AI Technical Summary

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to overcome the disadvantage that the forced cooling effect of the nose bridge area of ​​the cylinder head in the prior art cannot be guaranteed, thereby providing an engine cylinder head, through the guiding function of the deflector, the cooling water is forcibly guided to the nose bridge area, Ensure that there is sufficient water volume and flow rate in the nose bridge area, which can improve the cooling effect of the cylinder head and achieve the purpose of balanced cooling
