Description
Technical field
This utility model relates to the technical field of internal combustion engine, especially a kind of multi-cylinder diesel engine cylinder cap.
Background technology
The main function of cylinder head is closed cylinder top and collectively forms combustor with cylinder and top land.Also having cooling jacket in cylinder head, the cooling water hole on its end face communicates with the cooling water hole in cylinder block, to utilize recirculated water to cool down the high-temperature part such as combustor.Existing diesel engine cylinder cover belongs to low alloy steel castings, casting dimension accuracy requires to reach CT8-CT10,7 blowhole positions such as 3-Φ 70mm, 2-Φ 60mm, Φ 55mm, Φ 90mm are wanted accurately, location dimension meets the requirements, must not exceed standard, production difficulty is bigger, it is necessary to appropriate design cylinder cover structure, to meet the demand of high quality of production.
Utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, it is provided that a kind of high-quality multi-cylinder diesel engine cylinder cap.
This utility model solves its technical problem and be the technical scheme is that a kind of multi-cylinder diesel engine cylinder cap, including the cylinder cap body being fabricated by by alloy cast iron, the upper surface of described cylinder cap body is provided with several valve guide bushings being arranged in a row, valve guide bushing side is provided with several fuel injector bore being arranged in a row, fuel injector bore side is provided with several heater plugs being arranged in a row, described heater plug is positioned at the edge, upper surface of cylinder cap body, long cylinder bolt hole it is provided with between adjacent heater plug, the one side of cylinder cap body is provided with air intake duct, on cylinder cap body, the another side of relative air intake duct is provided with exhaust duct.
Further, described exhaust duct and air intake duct cross-distribution.
The beneficial effects of the utility model are: this utility model adopts alloy cast iron manufacture, and good mechanical property, long service life, reliability are high, it is possible to ensure the prescription that cylinder cap is significantly high, it is ensured that the high quality of production demand of whole diesel engine cylinder block.
