Embodiment Construction

[0013] A new type of diesel engine cylinder head, which includes a cylinder head body 1, a gas distribution top plate 2, such as figure 1 , figure 2 , image 3 As shown, the gas distribution top plate 2 is arranged on the cylinder head body 1, and its shape is a trapezoidal cube, which not only ensures the arrangement of the gas distribution mechanism in the form of oblique valves, but also effectively reduces the volume and quality of the cylinder head. The water cavity 3 is arranged in the cylinder head body 1, and the bearing column 8 is arranged in the water cavity 3. The water cavity is an inclined water cavity without a middle partition, and the air inlet channel 4 and the exhaust channel are arranged on the cylinder head body. 5. The cylinder head adopts a slanted four-valve structure. The intake port 4 and the exhaust port 5 are low-resistance straight air channels that are raised 30° upwards and connected in parallel, which reduces resistance, improves the flow coef...

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

[0001] technical field [0002] The invention belongs to parts on a diesel engine, in particular to a novel cylinder head of a diesel engine. Background technique [0003] With the improvement of power combat technology index requirements, the strategic development idea of ​​high power density diesel engine is put forward, which puts forward new requirements for the overall layout of the engine, the structural design of key components, and performance matching. The cylinder head is one of the key parts of the diesel engine, but the previous military power cylinder head in our country was large in size, heavy in weight and poor in reliability, which could no longer meet the requirements of high power density diesel engines. Contents of the invention [0004] The technical problem to be solved by the present invention is to overcome the above-mentioned deficiencies, and provide a cylinder head water chamber with an inclined water chamber structure, which can effectively impr...
