Description
Technical Field
The utility model belongs to a power equipment, specifically speaking especially relates to an air-cooled two-stroke gasoline engine.
Background
Two-stroke gasoline engines have a very wide application in the market, and compared with four-stroke gasoline engines, the two-stroke gasoline engines greatly simplify the structures of the two-stroke gasoline engines and reduce the weight of the two-stroke gasoline engines. The engine can run in any direction, and the flexibility of the engine is greatly increased. The power is large, the device is light and simple, the maintenance is convenient, the device can be moved for a long time, and the manufacturing cost is low. Therefore, the small two-stroke engine is mostly matched and sleeved in the fields of garden machinery, plant protection machinery, small agricultural machinery and the like, and the social conservation quantity is very large. With the further tightening of emission regulations, in order to reduce exhaust pollutants, a catalyst is added in a muffler of the two-stroke engine to promote secondary combustion, so that the temperature of the two-stroke gasoline engine is too high to meet the requirements of safety regulations in some regions.
In order to solve the defect of overhigh temperature of the two-stroke gasoline engine, the cooling methods of the two-stroke gasoline engine in the market at present are mainly divided into two methods, the first method adopts a water-cooled cooling system, and the cooling effect of the cooling system is better, but the defects of complex structure, heavy volume and the like exist. The second kind adopts air-cooled cooling system, and this type of cooling system structure is simpler, and small in size is light, but the cooling effect is relatively poor.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an air-cooled two-stroke gasoline engine to overcome the relatively poor defect of air-cooled two-stroke gasoline engine cooling effect among the prior art.
The utility model discloses an adopt following technical scheme to realize:
an air-cooled two-stroke gasoline engine comprises an oil tank, a rear half crankcase, a front half crankcase, a fan cover, an impeller, a cylinder body shield and a cylinder body, wherein an air inlet vortex channel is formed among the oil tank, the rear half crankcase and the front half crankcase, a cylinder body top air deflector is arranged above the cylinder body, and an air outlet vortex channel is formed among the front half crankcase, the cylinder body shield, the fan cover and the cylinder body top air deflector.
Preferably, the utility model discloses still include the muffler, be equipped with the muffler backing plate on the muffler.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses cooling crankcase, cylinder body, the muffler to the two-stroke gasoline engine, the circulation process of whole air current, the air current is effectual has cooled off whole two-stroke gasoline engine high temperature component, and the efficient has reduced the complete machine temperature of engine.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 and 2, the air-cooled two-stroke gasoline engine comprises an oil tank 1, a rear half crankcase 2, a front half crankcase 3, a fan cover 4, an impeller 5, a cylinder body shield 6 and a cylinder body 8, wherein an air inlet scroll is formed between the oil tank 1, the rear half crankcase 2 and the front half crankcase 3, a cylinder body top air deflector 7 is arranged above the cylinder body 8, the cylinder body top air deflector 7 is used for guiding cooling air to blow to the cylinder body 8, and the front half crankcase 3, the fan cover 4, the cylinder body shield 6 and the cylinder body top air deflector 7 form an air outlet scroll.
Preferably, the utility model discloses still include muffler 10, be equipped with muffler backing plate 9 on muffler 10, muffler backing plate 9 is used for blowing the cooling air guide to muffler 10.
The utility model discloses a theory of operation: after the two-stroke gasoline engine is started, high-temperature and high-pressure gas is generated in the cylinder body 8, part of the high-temperature and high-pressure gas is converted into kinetic energy to bring power to the gasoline engine, and the rest high-temperature and high-pressure gas is discharged into the atmosphere through the silencer 10. The gasoline engine runs, the crankshaft rotates to drive the impeller 5 to rotate, the impeller 5 rotates to generate negative pressure, the negative pressure generates airflow flowing, as shown in the direction of arrows in the figure, the airflow firstly enters the impeller 5 through an air inlet scroll formed by the oil tank 1, the rear half crankcase 2 and the front half crankcase 3, the airflow cools the oil tank 1, the front half crankcase 3 and the rear half crankcase 2 in the process, the airflow entering the impeller 5 passes through an air outlet scroll formed by the front half crankcase 3, the fan cover 4, the cylinder cover 6, the cylinder top air deflector 7 and the silencer gasket 9 to cool the cylinder 8 and the silencer 10 of the two-stroke gasoline engine and then enters the atmosphere, and in the whole airflow circulation process, the airflow effectively cools the whole two-stroke high-temperature component, and the temperature of the whole gasoline engine is efficiently reduced.
