Abstract
A diesel engine cylinder cover is a front cover special for a diesel engine cylinder. An intake valve, an exhaust valve, an intake channel, oil nozzles, an exhaust channel, an intake valve guide pipe hole, an exhaust valve guide pipe hole, radiating blades of the cylinder cover and a piston contact surface of a combustion chamber are arranged on a cylinder cover body. The piston contact surface of the combustion chamber is arranged at the bottom of the cylinder cover body, is provided with the intake valve and the exhaust valve, and is communicated with the intake channel and the exhaust channel respectively; the intake channel is arranged at the top of the cylinder cover, the exhaust channel is arranged at the rear part of the cylinder cover, and the directions of intake and exhaust are vertical to each other; the nozzles are arranged at the outer sides of the intake valve and the exhaust valve, are made of iron cast material, are wrapped in the cylinder cover and is communicated with the piston contact surface of the combustion chamber, and the communication position is arranged at the central line of the bottom of the cylinder cover; and the cylinder cover wholly adopts the design of arranging the radiating blades in longitudinal and transverse mixed directions so as to be beneficial to improving the radiating capacity of the cylinder cover. The diesel engine cylinder cover has the advantages of light weight, high combustion efficiency, high temperature resistance, small machining allowance, better manufacturability and good radiating capacity.
Description
One, technical field
The utility model belongs to Diesel Engine Technique Field, relates in particular to a kind of cylinder cover for diesel engine, belongs to Diesel Engine Technique Field.
Two, background technique
At present; The structure of multiple-purpose diesel motor cylinder head is: on the cylinder head body, be provided with firing chamber, intake valve, exhaust valve, intake duct, air outlet flue and oil nozzle; The firing chamber is positioned at the bottom of cylinder head body; One end of firing chamber communicates with air outlet flue through exhaust valve, and the other end of firing chamber communicates with intake duct through intake valve, and the direct firing chamber of oil nozzle is communicated with.Its exist burning indoor air flow mix relatively poor, combustion efficiency is low, heavy, machining allowance is not enough; Be prone to cause exhaust emissions to exceed standard, Economy is also undesirable.Simultaneously, the design of traditional air cylinder lid adopts a water cooling road to cool off, and is relatively poor to the cooling effect of oil nozzle.
Three, summary of the invention
The purpose of the utility model provide a kind of in light weight, thermal diffusivity good, combustion efficiency is high, resistant to elevated temperatures cylinder cover for diesel engine.
The technological scheme of the utility model is following: a kind of cylinder cover for diesel engine; On the cylinder head body, be provided with intake valve, exhaust valve, intake duct, oil nozzle, air outlet flue, intake valve guide hole, exhaust valve guide hole, cylinder head radiator shutter, piston of combustion chamber surface of contact; Wherein the piston of combustion chamber surface of contact is positioned at the bottom of cylinder head body; This piston of combustion chamber surface of contact is provided with intake valve and exhaust valve, and respectively with intake duct and air outlet flue UNICOM, intake duct is arranged on the cylinder head top; Air outlet flue is arranged on the cylinder head rear portion, and air inlet is vertical with discharge directions; The outside at the inlet and outlet door is provided with oil nozzle, and this oil nozzle adopts cast iron materials, and is coated in the cylinder head, communicates with said piston of combustion chamber surface of contact, is communicated with the position on the center line of cylinder head bottom; Cylinder head integral body adopts the design of mixed-arrangement radiating fin in length and breadth, helps to improve the heat dissipation potential of cylinder head.
Above-mentioned oil nozzle adopts the cast iron materials manufacturing, and is coated in the cylinder head body of being processed by aluminum alloy material, can improve the heat-resisting quantity of oil nozzle, makes cylinder head obtain higher performance.
Above-mentioned cast iron oil nozzle is " y " type, and its bottom communicates with the piston of combustion chamber surface of contact, is communicated with the position on the center line of cylinder head bottom.
The utility model is formed through high pressure die casting by aluminum alloy, makes cylinder cap casting have thin radiator shutter, and mixed-arrangement in length and breadth, has increased the area of contact of cylinder head and air, reaches favorable cooling effect.Simultaneously, adopt the cast iron oil nozzle, and be coated in the aluminium alloy cylinder lid, increase the heat-resisting quantity of oil nozzle, improve the overall performance of cylinder head.
The intake duct of the utility model is arranged on the cylinder head top, and air outlet flue is arranged on the cylinder head rear portion, and air inlet is vertical with discharge directions; Inlet and outlet are not disturbed mutually; And shortened the length of intake duct, improved the qi of chong channel ascending adversely coefficient, guaranteed that diesel engine has higher combustion efficiency.
The utlity model has in light weight, machining allowance is little, manufacturability is better, thermal diffusivity is good, combustion efficiency is high, advantage such as high temperature resistant.
