Abstract
The invention relates to a novel diesel engine cylinder cover, which comprises a cylinder cover body and an air distribution top plate, wherein the air distribution top plate is arranged on the cylinder cover body, and has a shape of a trapezoidal cube; a water cavity is formed in the cylinder cover body; bearing upright posts are arranged in the water cavity; the water cavity is an inclined water cavity without middle clapboard; the cylinder cover body is provided with an air inlet channel and an air outlet channel; the cylinder cover has an inclined four-valve structure; the air inlet channel and the air outlet channel are lifted 30 degrees upwards, and are low-resistance straight air channels in parallel connection; and the cylinder cover body is provided with two water inlets and a water outlet, and the water inlets and the water outlet are communicated with the water cavity. The water cavity of the cylinder cover is an inclined water cavity, the water flowing speed and the cooling effect are effectively improved, and a problem of a heat load brought by a high strengthened index is solved; and the novel diesel engine cylinder cover has the advantages of small volume, light weight and high reliability.
Description
Technical field
The invention belongs to the parts on the diesel engine, be specifically related to a kind of novel diesel machine cylinder head.
Background technique
Along with the raising of power war skill index request, the strategic development thinking of high power density diesel engine has been proposed, this general arrangement to motor, key part structure design, Performance Match etc. have proposed new requirement.Cylinder head is one of key component of diesel engine, and the volume of the military actuating cylinder lid of China is big before, quality heavy, poor reliability, can't satisfy the usage requirement of high power density diesel engine.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned deficiency; It is tilting water cavity structure that a kind of cylinder head water cavity is provided; Can effectively improve water velocity and cooling effect, solved the heat load problem that high reinforcement index is brought, and volume be little; In light weight, the novel diesel machine cylinder head of good reliability.
Technological scheme of the present invention: a kind of novel diesel machine cylinder head, it comprises gas cylinder lid, distribution top board, the distribution top board is arranged on the cylinder lid; Its profile is trapezoidal cube, and water cavity is arranged in the cylinder lid, is provided with the carrying column in the water cavity; Said water cavity is the tilting water cavity of no central diaphragm; The cylinder lid is provided with intake duct, air outlet flue, and said cylinder head adopts four tilting air valve structures, and intake duct and air outlet flue are for upwards raising 30 ° and be the parallelly connected straight air flue of low-resistance; The cylinder lid is provided with two water inlets and an osculum, and the water inlet is communicated with water cavity respectively with osculum.
The present invention compared with prior art has following beneficial effect:
1) this cylinder head has adopted the low-resistance intake and exhaust port, and air flue circulation coefficient reaches 0.65, satisfies the usage requirement of complete machine power per liter 90KW.
2) the cylinder head water cavity is designed to tilting water cavity structure, has effectively improved water velocity and cooling effect, has solved the heat load problem that high reinforcement index is brought.
3) the cylinder head profile is the case structure of band distribution top board, has not only guaranteed the layout of the distribution device of inclined valve form, has also effectively reduced the volume and the quality of cylinder head; Inner chamber is designed with the carrying column; Effectively improved rigidity, the intensity of cylinder head, the reliability of cylinder head can satisfy the usage requirement of the high power density diesel engine of maximum combustion pressure 25MPa, and small and exquisite attractive in appearance, the light weight of profile; Simple in structure, good reliability.
