Abstract
The utility model discloses a petrol engine and relates to a petrol engine assorted with a motorcycle. The petrol engine is a 145 engine, comprises a crankshaft and connection rod system, a cylinder and piston system, an ignition system, an intake valve, an exhaust valve and a muffler and is characterized in that the rotating radius of a crankshaft is in the range of 20.6mm to 20.8mm; and the diameters of a piston and a cylinder are in the range of 46.5mm to 47mm. Due to the adoption of the technical characteristics, preferably, the rotating radius is 20.8mm, i.e. the stroke is 41.6mm, so that the power is improved; meanwhile, the cylinder diameter is 47mm, so that the stressed area of the piston and the working volume of the engine are enlarged and the power of the engine is also further improved. By the improvement, the stroke bore ratio is equal to 0.89 and is more reasonable, gas is more sufficiently combusted to expand and do work than before, and the economic performance is improved.
Description
Technical field
The utility model relates to the petrol engine that a kind of matched motorcycle uses.
Background technique
145 motors are mini engine, supportingly on motorcycle, use, has higher technical merit, but As time goes on, increasing new architecture comes into operation successively, its technical merit and usability are seemed, and some falls behind, and particularly its power seems less, can't satisfy the use needs of present stage.
At present, the stroke of 145 motors has only 39.6mm, and cylinder diameter is 45mm, stroke bore ratio only is 0.88, its stroke is shorter, although the short stroke high speed performance is better, combustion gas expansion work distance is short, it is insufficient to expand, deficiency in economic performance, and delivery temperature height, thermal loss is big, oil consumption is higher, and is extremely uneconomical.
The model utility content
The utility model is at above-mentioned defective, and purpose is to provide a kind of petrol engine, and this petrol engine can improve power and can make its cylinder diameter than more becoming rationally, expand to doing work and compare over fully on the basis of rational deployment, improves its economic performance.
The technical solution of the utility model is: motor of the present utility model is 145 motors, include crankshaft rod system, cylinder piston system, ignition system, intake valve, exhaust valve and silencing apparatus, described crank up radius 20.6mm-20.8mm, piston and cylinder bore 46.5mm-47mm.
Preferably, described crank up radius is 20.8mm.
Preferably, described piston and cylinder bore are 47mm.
The utility model is owing to adopted above technical characteristics, and the preferred turning radius is 20.8mm, and promptly stroke is 41.6mm, has improved power; Cylinder diameter is 47mm simultaneously, has strengthened the swept volume of the lifting surface area and the motor of piston, has also further improved its power; And by above-mentioned improvement, stroke bore ratio is 0.89, makes cylinder diameter than more becoming reasonable, and combustion gas expand acting than abundant in the past, and economic performance is improved.
Description of drawings
Fig. 1 is a structural representation of the present utility model
1 is that bent axle, 2 is that piston, 3 is cylinder among the figure.
Embodiment
As shown in Figure 1, petrol engine of the present utility model comprises bent axle 1, and the turning radius of bent axle 1 is 20.6mm-20.8mm, and like this, the stroke of this motor had increased 2mm more originally, had improved power; Piston 2 and cylinder 3 increasing diameters are added to 47mm simultaneously, have further improved its power; Through improving its stroke bore ratio is more become rationally simultaneously, have more enthusiasm.The results showed that adopt this kind structure, the discharge capacity of motor can increase 63CC more originally, power is increased to 0.8kw, and moment of torsion increases 25Nm.
As a specific embodiment of the present utility model, bent axle 1 turning radius of the present utility model is elected 20.8mm as, and promptly stroke is 41.6mm, and piston 2 and cylinder 3 increasing diameters are added to 47mm.
