Description
Affiliated technical field
The utility model relates to a kind of motorcycle engine cylinder block, particularly a kind of motorcycle engine cylinder block of utilizing air to cool off.
Background technique
Operated by rotary motion has radiating fin on the existing motorcycle engine cylinder block, purpose is the heat radiation that strengthens cylinder block by air-cooled, to reduce the temperature of cylinder block, and an air Surface runoff at motor, the heat of the Engine Surface that only leaves, in-engine heat can not in time pass, therefore, temperature in engine cylinder head and the cylinder block is still higher, and cooling effect is extremely limited.Simultaneously, utilize this form of radiating fin heat radiation, be to rely on motorcycle in the process of moving, utilize the wind that flows that the heat on the engine cylinder is taken away, reach cooling purpose, and when motorcycle stopped to travel, the cooling effect of radiating fin was not good, and radiating fin just plays the purpose of a passive heat radiation.Certainly, what also have installs cooling water channel at above-mentioned cylinder block sidewall, makes cylinder block in by air cooling, also can be by water cooling.But because the length of cooling water channel is very short, cooling water can only be taken away the seldom heat of a part of cylinder block, and is still very poor to the cooling effect of cylinder block.
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 cylinder block of long service life, it cools off cylinder block from cylinder block inside, has improved the radiating effect of cylinder block.
The purpose of this utility model is to realize that by such technological scheme it includes the cylinder block housing, it is characterized in that: be provided with at least one air channel in the cylinder block housing, the cylinder block housing is provided with air intlet and the air outlet slit that communicates with air channel.
The utility model is work like this: air outlet slit is communicated with the engine air filter suction port, and the air-strainer air outlet is communicated with Carburetor.Behind engine start, piston reciprocating type motion in the cylinder, make and form negative pressure in the cylinder, cool exterior air is drawn in the air channel under atmospheric effect, enter in the Carburetor through air outlet slit, pipe, air-strainer, the air that enters in the Carburetor fully with after the gasoline of atomizing mixes is fed in the firing chamber of cylinder again.So constantly circulation makes the heat of cylinder block along with constantly entering of cool air heat exchange take place constantly, has reached the purpose that reduces the temperature of cylinder block.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 with cylinder block in heat carry out heat exchange, so so long as motor is not out of service, cool ambient air can both initiatively be cooled off cylinder block from cylinder block inside.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, make that petrol molecule is as easy as rolling off a log to spread, improve the atomizing ratio of gasoline, increased the gasoline and Air mixing ratio of atomizing, significantly 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 cools off cylinder block from cylinder block inside, has improved the radiating effect of cylinder block, makes the temperature of cylinder block low, it is very reliable to work.
