Abstract
The utility model relates to a motorcycle engine with arc air passage, belonging to the art field of motorcycle manufacture, composing mainly a cylinder head with admission gear, a cylinder body, a piston connecting rod and crank shaft assembly, a magnetor, a belt, a driving change wheel, a driven change wheel, a reducer, a foot starting mechanism, a driving change wheel with clutch and a carburetor assembly, which is characterized in that the inlet passage on the cylinder head is looked as circular arc from axial direction of the cylinder. The utility model has the advantages that after the air entering the cylinder along the circular arc air passage, the mixing condition of air and fuel can be greatly improved, thus, the fixed air can be much easier to form the homogeneous mixture gas, which can be favorable to full combustion of fuel, can improve dynamic performance of engine and discharge quality of motorcycle.
Description
Technical field
The utility model relates to a kind of motorcycle engine, belongs to motorcycle manufacturing technology field.
Background technique
Motorcycle engine is as the power plant of motorcycle, the performance of motorcycle played a part very important, and the shape of the gas-entered passageway that communicates with the firing chamber in engine cylinder head structure will be to certain influences of generation such as engine power performance.Existing motorcycle engine is from its cylinder-bore axis direction, gas-entered passageway in its cylinder head is type linearly all, motor with this kind shape structure air flue is in suction stroke, in air flue, do not form certain eddy current from the gas in the atmosphere, though the flow losses of this kind shape structure passage gas are little, flow coefficient is bigger, but the air that enters the firing chamber can not fully mix with fuel, be unfavorable for the abundant burning of fuel, thereby produce adverse influence to the power character of motor, Economy and to the discharging of motorcycle.
The model utility content
The purpose of this utility model provides a kind of motorcycle engine of having improved gas-entered passageway shape structure in the cylinder head, it can make gas enter cylinder and the abundant mixed combustion of fuel with preferable airflow direction, thereby improves the discharge quality of engine power performance and motorcycle.
Motorcycle engine with camber air flue described in the utility model mainly is made up of the active change pulley of cylinder head, cylinder block, piston rod crankshaft assembly, magnetogenerator, belt, driving change pulley, driven change pulley, retarder, pin starting mechanism and the band clutch of band distribution device and carburetor assembly etc., on cylinder head, offer gas-entered passageway and exhaust passage, from the cylinder-bore axis direction, this gas-entered passageway is circular arc type.
Motorcycle engine with camber air flue described in the utility model, because the gas-entered passageway in its cylinder head is seen from the cylinder-bore axis direction and is circular arc type, air-flow flows along circular arc air flue internal surface in air flue, thereby air-flow had just been formed along the gas flow of cylinder tangent to periphery direction before arriving cylinder, the airflow design of air flue makes gas flow lose relative straight line type air flue and little, but improved the troubled water of gas and fuel widely, make it to be easier to form the mixed gas of homogeneous, flame propagation speed in the firing chamber, can suitably improve compression ratio, thermal efficiency height.In addition, it is more abundant that good mixing gas helps burning, thereby improved the discharge quality of engine power performance and motorcycle.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is described in further detail.
Fig. 1 is a gas in the motorcycle engine cylinder head gas-entered passageway with camber air flue described in the utility model flows to schematic representation;
Fig. 2 is that gas flows to schematic representation in cylinder.
Embodiment
As shown in Figure 1, this motorcycle engine mainly is made up of the active change pulley of the cylinder head, cylinder block, piston rod crankshaft assembly, magnetogenerator, belt, driving change pulley, driven change pulley, retarder, pin starting mechanism of band distribution device and band clutch and carburetor assembly etc., on cylinder head, offer gas-entered passageway 1 and exhaust passage, valve seat 2 is installed in the valve-seat bore of gas-entered passageway end; From the cylinder-bore axis direction, this gas-entered passageway is circular arc type.
Claims (1)
1, a kind of motorcycle engine with camber air flue, the active change pulley of main cylinder head by the band distribution device, cylinder block, piston rod crankshaft assembly, magnetogenerator, belt, driving change pulley, driven change pulley, retarder, pin starting mechanism and band clutch and carburetor assembly etc. are formed, on cylinder head, offer gas-entered passageway and exhaust passage, it is characterized in that, from the cylinder-bore axis direction, this gas-entered passageway is circular arc type.
