Description
Technical field
The utility model relates to a kind of motor, particularly a kind of motorcycle engine of utilizing air to cool off.
Background technique
Motorcycle engine can produce a large amount of heat when work, the temperature of motor is raise.Too high temperature not only can make efficiency of engine reduce, and causes the damage of each component on the motor easily, and rate of fault height, working life lack.
The existing motorcycle engine of utilizing air to cool off generally is on cylinder head and cylinder block radiating fin to be set, it is performed such cooling: in the process of moving, the formed wind of air contacts fully with radiating fin on the motor, carry out heat exchange, thereby reach the purpose of cooled engine.This air-cooled motor exists following deficiency:
1. air is only in the Surface runoff of motor, the heat of the Engine Surface that only leaves, and in-engine heat can not in time pass, and therefore, the temperature in engine cylinder head and the cylinder block is still higher, and cooling effect is extremely limited.Simultaneously, utilizing this form of radiating fin heat radiation, must be can dispel the heat in the process of moving at motorcycle, when motorcycle stops to travel, radiating fin does not just reach the effect that motor is cooled off, and radiating fin just plays the purpose of a passive heat radiation.
2. existing motorcycle engine just relies on the limited suction of piston to suck ambient air by air-strainer, for winter or weather colder the time, extraneous air temperature is just lower, particularly at northern area or in hypobaric hypoxia area, plateau, the air that the motor inlet temperature is low, air pressure is also low, make oxygen molecule and petrol molecule be not easy the evaporation diffusion, intermolecular arranging density is low excessively, be unfavorable for the atomizing of mixed gas, cause that burning in the cylinder is insufficient, power decline, excessive oil consumption, shortened working life.
Announced that in CN2515098Y a kind of name is called the utility model patent of " motorcycle that contains forced air cold engine ", it is in the car body bottom front and back wheels to be housed, on the car body between the front and back wheels motor is housed, described motor is provided with cylinder, cylinder is connected with crankcase, the rotor of crankcase is provided with cooling fan, outside at cylinder and cooling fan is surrounded by wind scooper, the suction port of cylinder is provided with Carburetor or EFI mouth, the suction port of Carburetor or EFI mouth is communicated with the outlet of air-strainer by trunnion, on the wind scooper of cylinder head, have an air outlet, the suction port of air-strainer air outlet direct and on the wind scooper is communicated with, and the air outlet on the wind scooper is provided with a metal filter screen.Though this patent can solve above-mentioned second problem, but it still fails to solve first problem, and fail to be provided with air inlet on the wind scooper of this patent, in the time of incipient, fan utilizes the air in the wind scooper only the temperature of Engine Surface temporarily can be cooled off, but growth along with the time, fan constantly blows into air EFI mouth passage, make air enter engine chamber, the waste gas that is produced after burning in the firing chamber is constantly got rid of the external world, and does not have the benefit of extraneous air to go into, formed negative pressure in the wind scooper that makes, the temperature of Engine Surface is not cooling not only, and is more and more higher on the contrary, finally causes motor to damage.
Summary of the invention
The purpose of this utility model just provide a kind of simple in structure, rate of fault is low and the active air-cooled type motorcycle engine of long service life, it not only can strengthen the radiating effect of cylinder head and cylinder block, and make the fuel diffusion that better atomizes, become more all even sufficient burning mixture with air mixing, significantly improved the utilization ratio of fuel.
The purpose of this utility model is to realize by such technological scheme, it comprises cylinder head, cylinder block and air-strainer, it is characterized in that: be provided with air-cooled passage between the lower end surface of cylinder head and the upper-end surface of cylinder block, cylinder head and/or cylinder block are provided with import and the outlet that communicates with air-cooled passage.
During use, the import of air-cooled passage directly is communicated with ambient atmosphere, and outlet connects the air intlet of air-strainer by tracheae.Behind the engine start, the to-and-fro motion of piston forms air-intake negative-pressure in cylinder.Cool exterior air initiatively is drawn in the air-cooled passage by import under the effect of negative pressure, again through air-strainer filter and with Carburetor in after the fuel mix that atomizes, enter the firing chamber of cylinder together, work by combustion is to support the external outputting power of motor.In this process, cool air continuous and cylinder head and/or cylinder block generation heat exchange that the air-cooled passage of flowing through is interior, one side reduces the temperature of cylinder head and/or cylinder block, fully cooling air cylinder head and/or cylinder block, to guarantee the proper functioning of motor, prolonged the working life of motor simultaneously; On the other hand, enter the interior air of Carburetor because of by cylinder head and/or cylinder block preheating, make the easier diffusion of fuel of atomizing, air is more abundant with mixing of fuel, and formed burning mixture flammability is better, has effectively improved the utilization ratio of fuel.
Owing to adopted technique scheme, the utlity model has simple in structure, rate of fault is low and the advantage of long service life, it has improved the radiating effect of motor, the temperature of cylinder head and cylinder block is low, can effectively ensure the normal operation of motor, and it is very reliable to work, also improved the atomizing ratio of gasoline simultaneously, increase the gasoline and Air mixing ratio of atomizing, significantly improved the utilization ratio of burning, and increased the externally power of output of motor to a certain extent.
