Abstract
A motorcycle with an air blast cooling engine is equipped with a motorcycle body whose lower portion is equipped with a fore and a rear wheels, and an engine is arranged between the portion of the fore and the rear wheels of the motorcycle body. The engine is equipped with a cylinder which is connected with a crankcase with a cooling fan being arranged on a rotor of the crankcase, and a wind-guiding cover is packaged out of the cylinder and the cooling fan. A carburetor or an electrical nozzle is arranged in an air inlet of the cylinder, and an air inlet of the carburetor or the electrical nozzle is communicated with the outlet of an air cleaner through a bronchia. An air outlet equipped with a metal filter is opened on the wind-guiding cover of the top of the cylinder, which is directly communicated with the air inlet of the air cleaner. The utility model modifies the traditional air intake mode of the engine, the heat energy produced by the engine is reasonably provided for the air intake system through the cooling fan of the rotor, which greatly improves the atomizing rate of the gaseous mixture. The utility model with great effect has simple structure in design and is easy to utilize.
Description
Technical field
The utility model relates to a kind of motor bike, particularly a kind of motor bike that contains forced air cold engine.
Background technology
The motor bike that contains forced air cold engine in the prior art, it is provided with car body, front and back wheel is equipped with in the car body bottom, on the car body between the front and back wheel driving engine is housed, described driving engine 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 admission port of cylinder is provided with carburettor, the admission port of carburettor is communicated with the outlet of airfilter by trunnion, the problem of its existence is: driving engine only sucks outside air by the limited suction of piston by airfilter, and for winter, outside air temperature is low, particularly in the north or hypobaric hypoxia area, plateau, driving engine sucks so not only cold air and presses but also low air, makes oxygen molecule and petrol molecule be difficult for the evaporation diffusion, and intermolecular arranging density is low excessively, be unfavorable for the atomizing of mixture gas, cause the power of driving engine to descend, it is insufficient to burn, excessive oil consumption, tail gas pollution increases, reduction of service life.The admission port of traditional in addition airfilter is exposed to the outside, during high vehicle speeds, can produce negative pressure at the admission port of airfilter, causes the oxygen supply deficiency, owing to air pressure is crossed the low mixture gas atomization badness that makes, causes the mixture ratio imbalance of mixture gas simultaneously again.
Summary of the invention
The technical problems to be solved in the utility model is: at the deficiencies in the prior art, proposed a kind of motor cycle that changes traditional intake method, it improves the condensation rate of engine mixed gas with the most simple and practical method.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of motor bike that contains forced air cold engine, it is provided with car body, front and back wheel is equipped with in the car body bottom, on the car body between the front and back wheel driving engine is housed, described driving engine is provided with cylinder, with cylinder bonded assembly crankcase, the rotor of crankcase is provided with cooling fan of engine, outside at cylinder and cooling fan is surrounded by wind scooper, the admission port of cylinder is provided with carburettor or EFI mouth, the admission port of carburettor or EFI mouth is communicated with the outlet of airfilter by trunnion, be characterized in: have air extractor duct on the wind scooper of cylinder head, this mouthful is located at the high-temperature zone of driving engine, the admission port of airfilter directly with wind scooper on air extractor duct be communicated with by air-guiding aisle or directly link to each other.Technical solution of the present utility model also is applicable to the driving engine of charged spray.The blast air that the utility model utilizes the fan on the engine rotor to produce makes the driving engine cooling, simultaneously again with this hi-heat blast air by carburettor or blow to EFI mouth passage, utilize the heat energy of driving engine self, make oxygen molecule and petrol molecule evaporation diffusion in the mixture gas, intermolecular arranging density is increased, improve the condensation rate of mixture gas.
The technical problems to be solved in the utility model can also come by the following technical programs further to realize that the air extractor duct on the wind scooper is provided with the dustproof husky net of a metal filtration, plays filtration for the first time.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, in design, the suction circuit of air is short more good more, and the cleanliness of air will get well, so the airfilter admission port is set directly at high temperature air extractor duct place, wind scooper top.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, and the air extractor duct area that wind scooper leads to the airfilter admission port is 0.3～0.6 times of piston cross-sectional plane.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, and the air extractor duct that wind scooper leads to the airfilter admission port is made up of several apertures.Some apertures by air extractor duct make the hot gas that enters airfilter evenly by the filtration sponge of fil, prolong the service life of filtering sponge, and air inlet are abundant.
The utility model compared with prior art, changed the traditional intake method of motor cycle engine, the heat energy of motor cycle engine self generation is reasonably offered the air system of driving engine by epitrochanterian cooling fan, improved the condensation rate of mixture gas greatly, avoided simultaneously because high vehicle speeds produces the phenomenon of negative pressure at the admission port of airfilter.The utility model is fit to engine principles, and aspect simple and practical, the most suitable motor cycle engine particularly contains the pedal motorcycle of force-air cooling, comprises EFI and multi-cylinder cooling motorcycle engine water.Project organization of the present utility model is simple and easy to do, and it is big to take effect.
