Abstract
The utility model relates to a liquid-cooled engine for a motorcycle; wherein, a liquid-cooled metal pipe is arranged close to the external wall of the cylinder body (combustion chamber) and both ends of the cooling pipe are respectively communicated with the upper and lower liquid inlet and outlet on a liquid radiator, which is arranged on the frame, so as to form an auto-convection closed cycle liquid cooling system. The utility model has the advantages of simplicity, feasibility, good cooling effect, oil saving, power improvement, steady performance, prolonged service life and so forth.
Description
The utility model relates to motorcycle engine cooling technology field.
At present, what extensively adopt in the motorcycle manufacturing industry is that air displacement is at the air-cooled single cylinder petrol engine below 250 milliliters, the topmost shortcoming of this motor is cooling effect other defective bad and that cause thus, when motorcycle the summer of sweltering heat long-time high load travel or long-time low speed large throttle travels, especially when the long-time climbing of motorcycle is travelled, will occur causing the engine overheat cylinder block to expand because of cooling effect is bad, it is big that piston and cylinder block inwall gap become, piston ring seals bad generation gas leak phenomenon, oil consumption increases, power reduces, noise and exhaust emissions increase, high temperature has also quickened cylinder inner wall and wear of piston-rings, make the very fast aging of motor, decreased performance has shortened working life of motor, directly has influence on the quality of whole motorcycle.In recent years disclosed water cavity (cover) cooling engine for motor cycle water, big because of implementing difficulty, cost increases high, is difficult for being adopted by manufacturer; Disclosed motorcycle oil cold engine, because of its cooling mainly be the lubricating oil of gear-box and piston, rather than produce the position at the thermal source of motor and be cylinder block (firing chamber), not obvious as an utterly inadequate amount to the improvement of engine cooling effect.
The purpose of this utility model is the deficiency that overcomes above-mentioned motorcycle engine, and a kind of simple and easy to do, good cooling results is provided, the power height, wearing and tearing less, the motorcycle liquid-cooled engine of long service life, stable performance.
The purpose of this utility model realizes by following proposal.
Outside motorcycle engine thermal source generation position is engine cylinder (firing chamber), be close to cylinder block outer wall and be provided with metal thin-wall liquid cooling tube such as the copper pipe that coils a few, aluminum pipe, iron pipe, the two ends of pipe are respectively liquid entering hole and liquid outlet, with pipeline respectively be installed in vehicle frame on the hot up and down cold liquid in-out mouth of box-shaped liquid radiator be communicated with and constitute the liquid closed circuit circulatory system, the all good non freezing solution body of falling heat-transfer flowability in cylinder body cooling tube and the radiator, when motorcycle engine is worked, the metal tube that is full of cooling liquid of cylinder block outer wall coiling directly cools off the cylinder body wall, the upper reaches entered liquid radiator after coolant temperature in the pipe raise, dirty the entering in the metal cooling-pipe of cold liquid in the radiator, go round and begin again, form the automatic closed-circuit liquid stream of cold and hot convection current, all the time the lower liquid of temperature is flowing in the cooling tube of cylinder block (firing chamber) outer wall, reduced the temperature of cylinder block (firing chamber) wall effectively, cylinder can not crossed thermal expansion, piston and cylinder inner wall are in good cooperation closed state all the time, the oil gas sufficient combustion, produce bigger heat energy with less fuel oil, improve power, reduce wear, reduce noise and exhaust emissions, cylinder block (firing chamber) outer wall cooling tube has two kinds of jatharapanvartanasana coil pipe (as schematic representation 1) and spiral coils (as schematic representation 2), cooling tube will be close to cylinder block outer wall, when cooling tube passes through radiating fin, will there be the gap passage at the radiating fin place that passes through, the cooling tube of float tolerance motor can be coiled in the junction of cylinder block and cylinder block and cylinder head, the junction of cylinder block and crankcase, the cooling tube of big air displacement motor can be coiled between the cylinder block radiating fin, can increase coolant rate by increasing the cooling tube diameter in order to improve cooling effect, or increase coiling number of turns increase film-cooled heat, increase radiator area and capacity and improve radiating effect.
The utility model is owing to direct thermal source generation place at motor is to be provided with liquid automatic cycle cooling system on cylinder block (firing chamber) outer wall, simple and easy to do, good cooling results makes the stable performance of motorcycle engine, prolong working life, and relevant every technical order is improved.
Below in conjunction with accompanying drawing the utility model is further specified
Fig. 1 is a motorcycle liquid-cooled engine revolution coil pipe block structure schematic representation
Fig. 2 is a motorcycle liquid-cooled engine spiral coil block structure schematic representation
As shown in the figure, on cylinder block 1, liquid cooling tube 3, cooling tube lower end 2 and the cold liquid outlet in radiator bottom pipeline connection are set with jatharapanvartanasana coil pipe or spiral coil, there are gap passage the 6, the 7th, cylinder block air inlet or relief opening in the radiating fin place that cooling tube upper end 4 and radiator top hydrothermal solution import pipeline connection, cooling tube are passed through during by radiating fin 5.Cylinder body can exchange with existing common cylinder body, is convenient to repacking and maintenance.
