Detailed Description
The technical scheme of the utility model is further described below with reference to the accompanying drawings and examples.
As shown in fig. 1-3, the embodiment of the utility model provides a diesel engine cylinder cover, which comprises a cylinder cover body 1, wherein a plurality of cooling fins 2 are arranged on the cylinder cover body 1, a cylinder cover mounting cavity 10 is formed by enclosing a surrounding plate 3 on the cylinder cover body 1, an oil sprayer mounting hole 11 is communicated with the cylinder cover mounting cavity 10 of the cylinder cover body 1, an oil sprayer mounting column 4 is arranged on the cylinder cover body 1, the oil sprayer mounting hole 11 is arranged on the mounting column 4, a cooling through hole 5 penetrating through the cooling fins 2 is arranged on the cylinder cover body 1, and the cooling through hole 5 is communicated with the mounting column 4.
The process of the utility model is as follows when in use, the oil sprayer is arranged on the oil sprayer mounting hole 11 of the mounting column 4 of the cylinder cover body 1, the valve component is arranged at the same time, after the cylinder cover body 1 is assembled on the cylinder body of the diesel engine, the cylinder cover body 1 radiates heat through the radiating fins 2 on the cylinder cover body when the engine is air-cooled, meanwhile, the air blown by the radiating fan enters the radiating through holes 5 arranged on the cylinder cover body 1, and the air flows out of the radiating through holes 5 after flowing into the radiating through holes 5 because the radiating through holes 5 are communicated with the mounting column 4, and the accumulated heat of the mounting column 4 is taken away, so that the oil sprayer arranged on the cylinder cover body can be well radiated.
