Abstract
The utility model relates to an injection fuel line of right box lubrication and piston cooling of a motorcycle engine, which has simple structure, low production cost, and good piston lubrication andcooling effect; the injection fuel line comprises a right box, a cylinder body and a piston; the cylinder body is arranged on a combining surface of the cylinder body of the right box, a cylinder body sleeve is matched with a cylinder mounting hole of the right box, and the piston is arranged in the cylinder body; an oil injection hole, pointing to the top part of inner cavity of the piston, is arranged on the right box, and the oil injection hole is communicated with a main oil path of the right box body by an oil pipeline, in the way, engine oil injected from the oil injection hole reachesthe top part of the inner cavity of the piston directly and avoids a piston pin and a connecting rod of the inner cavity of the piston, thereby effectively improving the cooling and lubricating effectof the piston.
Description
Technical field
The utility model relates to the lubricated of a kind of motorcycle engine and cooling oil circuit, is specifically related to the injection oil circuit of the lubricated and cooling piston of motorcycle engine right case.
Background technique
At present, all motorcycle engines on the market, piston all directly links to each other with the firing chamber, and high temperature, high pressure that burning produces directly act on piston crown; Simultaneously, piston is to-and-fro motion in cylinder, also can produce very high temperature with the cylinder inner wall friction.In order to guarantee the reliability of pistons work, prolong the working life of piston simultaneously, just must constantly cool off and lubricate piston.For this reason, adopted a series of technological schemes to solve this difficult problem in the industry.In early days, the lubricated and cooling of piston, mainly the rotation by crankshaft ﹠ connecting makes machine oil be splashed to piston cavity, makes part machine oil be penetrated into cylinder inner wall by the oilhole of piston ring land simultaneously, thereby reaches cooling and lubrication effect.Afterwards, along with the discharge capacity of motorcycle engine increases, the heat load of piston also increased, and utilized the crankshaft ﹠ connecting can not practical requirement to the mode of piston splash lubrication and cooling.Personnel have opened up the new oil circuit to piston cavity top jet machine oil again in the industry, as utility model patent ZL200520032864.7, its claim: for be provided with a hole on right bent axle body, this hole communicates by the former lubricating oil path of oil pipe and motor, constitutes bleed off circuit; Utility model patent ZL200720124028.1 and for example, its claim: another oil circuit branch that on right case, has additional lubricated and cooling piston, this oil circuit branch communicates with main oil gallery, oil pipe one end is communicated with oil circuit branch, the other end stretches into the piston inner wall top, and oil pipe embeds in the oil circuit branch and by the positioning step on the oil pipe and locatees simultaneously.Above-mentioned both communicates with oil circuit by oil pipe, has increased the part portion of former motor, and the both complicated assembly structure of motor has increased the relative cost of production motorcycle engine again; In addition, because piston cavity has wrist pin and connecting rod to step down, in fact, those skilled in the art are difficult to realize to the cooling of piston or lubricated according to technique scheme.
