Description
Technical field
The utility model relates to a kind of motor, the cold motorcycle engine in particularly a kind of geomantic omen.
Background technique
Motorcycle engine can produce a lot of heats 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 that radiating fin is set on cylinder block, it is performed such cooling: in the process of moving, the formed wind of air contacts fully with radiating fin on the motor, carries out heat exchange, thereby reaches 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 the engine cylinder is still higher, and cooling effect is extremely limited.
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 temperature of Engine Surface can also 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 improve the radiating effect of cylinder block, cylinder head, but also improved the atomizing ratio of gasoline, increase the gasoline and Air mixing ratio of atomizing, significantly improved rate of combustion.
The purpose of this utility model is to realize by such technological scheme, it comprises cylinder block, cylinder head, it is characterized in that: the lower end surface by cylinder head surrounds a cooling air channel between the upper-end surface of cylinder block, cylinder head and/or cylinder block are provided with import and the outlet that communicates with cooling air channel, in cylinder head, be provided with air channel, the outlet of cooling air channel communicates with air channel, the suction port of air channel is positioned on the sidewall of cylinder head, and the air outlet is positioned on another sidewall of cylinder head.
In the utility model, the suction port of air channel, the import of cooling air channel all communicates with ambient atmosphere, the outlet of air channel is communicated with air-strainer by tracheae, it is work like this: behind engine start, piston reciprocating type motion in the cylinder, make and form negative pressure in the cylinder, cool exterior air is drawn under atmospheric effect in the gas cooling passage of air channel and cooling air channel formation, pass through air outlet slit again, tracheae, air-strainer enters in the Carburetor, and the air that enters in the Carburetor fully with after the gasoline of atomizing mixes is fed in the firing chamber of cylinder.So constantly circulation makes the heat of cylinder block, cylinder head along with constantly entering of cool air heat exchange take place constantly, has reached the purpose that reduces the temperature of cylinder block, cylinder head.Because ambient air is that initiatively to be pumped into engine combustion by the negative pressure in the cylinder indoor, make air stream in cylinder block, cylinder head with cylinder block, cylinder head in heat carry out heat exchange, so so long as motor is not out of service, ambient air can both initiatively cool off cylinder block, cylinder head.Simultaneously, carry out the hot air that forms after the heat exchange, constantly be drawn in the Carburetor by air-strainer, hot air is with after petrol molecule mixes, and makes that petrol molecule is as easy as rolling off a log to spread, and increased the atomizing of mixed gas, improved the efficient of burning.
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 cylinder block, cylinder head, make the temperature of cylinder block, cylinder head low, can effectively ensure the normal output of engine power, it is very reliable to work, and has also improved the atomizing ratio of gasoline simultaneously, increase the gasoline and Air mixing ratio of atomizing, significantly improved rate of combustion.
