Description
Technical field
The present invention relates to a kind of four stroke engine oil cooling system.
Background technique
Modern motor needs more and more higher power, in order to make motor obtain more high power, people have adopted many schemes, but these schemes all can not make engine operating temperature raise with avoiding, are unacceptable from the performance of motor and the rising of reliability temperature.The too hot loss that just means power of motor descends power character, Economy, and too high cylinder head temperature also influences motor working life simultaneously.
Therefore, people adopt the whole bag of tricks to come cooled engine, and as air-cooled, water-cooled commonly used at present, but the cooling effect of existing air cooling system is general, constituent is that its structure of cooling effect that reaches desirable is relatively complicated again, all can't be not only simple but also reduce the temperature of motor effectively.
Summary of the invention
The objective of the invention is provides a kind of simple in structure in order to overcome deficiency of the prior art, the four stroke engine oil cooling system of good heat dissipation effect.
In order to achieve the above object, the present invention adopts following scheme:
A kind of four stroke engine oil cooling system, it is characterized in that comprising the Coolers oil groove that is arranged on around the engine chamber top, in the cylinder head of described motor, be provided with the wall that timing chain passage and described Coolers oil groove can be separated, on described cylinder head, be provided with the machine oil rising passway that is communicated with described Coolers oil groove, described machine oil rising passway is connected with the engine motor oil oil sump of cylinder block bottom, between described machine oil rising passway and engine motor oil oil sump, be connected with an oil pump, be provided with the machine oil decline pipeline that a plurality of and described Coolers oil groove is connected on described cylinder block, described machine oil decline pipeline is connected with described engine motor oil oil sump.
Aforesaid a kind of four stroke engine oil cooling system is characterized in that being provided with the machine oil balance cylinder between described machine oil decline pipeline and engine motor oil oil sump.
Aforesaid a kind of four stroke engine oil cooling system is characterized in that described machine oil rising passway is connected with oil supply pipeline in the engine lubrication system, and described oil pump can be respectively carried machine oil simultaneously to the described oil cooled system lubrication system of unifying.
Aforesaid a kind of four stroke engine oil cooling system is characterized in that described machine oil decline pipeline is arranged on described cylinder block inside.
Aforesaid a kind of four stroke engine oil cooling system is characterized in that described machine oil rising passway is arranged on described cylinder block inside.
Aforesaid a kind of four stroke engine oil cooling system is characterized in that described machine oil rising passway and the engine oil pipeline that is arranged in the described cylinder block is connected, and described engine oil pipeline one end is connected with described engine motor oil oil sump.
In sum, the present invention with respect to its beneficial effect of prior art is:
One, oil cooling of the present invention system adopts at the periphery of the top of combustion chamber of motor and cylinder block and obtains cooling by machine oil mobile.The machine oil that flows directly contacts motor internal heat generation part such as cylinder head, cylinder block, takes away heat, and gets back in the sump along oil circuit.The oil cooling system has improved the life-span of motor, and does not but increase the motor volume when improving power;
Two, cooling and lubrication system only adopt a single rotor engine oil pump to drive in the cooling system of the present invention, do not need to use two fully independently oil pump or have the oil pump of two rotors.Effectively provide cost savings, also do not increase the volume of motor;
Three, be provided with the wall that timing chain passage and described Coolers oil groove are separated among the present invention in cylinder head inside, prevent that effectively timing chain from producing violent stirring to machine oil when work, thereby produce micro-bubble, cause the forfeiture of engine oil pressure.
Four, the present invention effectively improves in-engine compression ratio, has increased the phase range of valve timing, can reduce the gap, makes the component of motor compact more, can effectively reduce discharging, compares the extra rate that increases with air cooling engine.
