The traditional oil mist lubrication mode is changed, the engine oil does not participate in combustion, the pollution is reduced, the effect is good, and the service life is long.
Description
The utility model belongs to the lubricating fitting of the improvement of motorcycle two stroke IC engine lubricating fitting, particularly two stroke IC engine.
Current, import or homemade the lubricated of motorcycle two stroke IC engine all are to adopt oil mist lubrication, machine oil enters cylinder body and mixes the formation mixed gas with combustible gas, combustible gas and machine oil burn simultaneously during burning, produce a large amount of smog and carbon distribution, make lubricating cylinders bad, quickened mechanical wear, cause pollution atmosphere environment.Have breaking of tail gas purification plant is installed on the outlet pipe of part motorcycle, reduced pollution, but exist working life short, also can cause engine power to descend atmosphere.
The purpose of this utility model is to provide a kind of lubricating fitting of two stroke IC engine, changed the lubricating system of traditional two stroke IC engine, avoided oil mist lubrication, machine oil is participated in burning and is produced a large amount of smog, cylinder body produces the drawback of carbon distribution, take regularly, fixed point, quantitatively dividing section to concentrate for machine oil is lubricated cylinder body, piston, bent axle, machine oil is not participated in burning, makes high lubricating effect, has reduced the pollution to atmosphere environment, and can prolong working life of two stroke IC engine, do not influence the outputting power of internal-combustion engine.
The utility model is achieved in that a kind of lubricating fitting of two stroke IC engine, the cylinder body that comprises two stroke IC engine, the crankshaft ﹠ connecting of installing in the crankcase, piston and plunger-type fuel pump, the annular groove bottom that piston ring is housed at piston is being provided with the oil ring groove that oil ring is housed, in oil ring groove, be provided with the downward-sloping through hole that leads to wrist pin, on cylinder liner, offer acclivitous through hole, be communicated with through hole on the cylinder liner at the oil duct that is provided with on the cylinder body, crankcase body is provided with oil nozzle, when piston is positioned at top dead center or lower dead center, oil ring groove on the piston is communicated with through hole on the cylinder liner, oil nozzle is aimed at bent axle pin-and-hole, plunger-type fuel pump fuel feeding.
During the utility model work, accurately control plunger-type fuel pump by cam, when piston reaches top dead center or lower dead center, oil pump produces oil pressure, makes lubricant oil enter the oil ring of piston from the oil duct of cylinder body, and oil ring is distributed on lubricant oil on the cylinder wall of cylinder liner and carries out pressure lubrication, lubricant oil is also by leading to wrist pin to the through hole that has a down dip in the piston oil annular groove, the lube pistons pin, the oil nozzle on the crankcase body is lubricated crankpin to the oil spout of bent axle pin-and-hole.The utility model has changed the mode of the traditional oil mist lubrication of two stroke IC engine, machine oil is not participated in burning, thereby significantly reduced casing wall and produced carbon distribution, take regularly, fix a point, quantitatively for pressure oil cylinder body, piston and bent axle be lubricated by plunger-type fuel pump, high lubricating effect has prolonged the working life of two stroke IC engine, but also does not influence the outputting power of internal-combustion engine, because lubricant oil is not participated in burning, has reduced the pollution to atmosphere environment.
Fig. 1 is a structural representation of the present utility model, below in conjunction with accompanying drawing the utility model is further described, a kind of lubricating fitting of two stroke IC engine, the cylinder body that comprises two stroke IC engine, the crankshaft ﹠ connecting of installing in the crankcase, piston and plunger-type fuel pump, the annular groove bottom that piston ring (2) is housed at piston (3) is being provided with the oil ring groove (13) that oil ring (1) is housed, in oil ring groove (13), be provided with the downward-sloping through hole (5) that leads to wrist pin (14), on cylinder liner (8), offer acclivitous through hole (4), through hole (4) is 32 °～37 ° with horizontal angle, after the top rade of through hole (4) can prevent to stop, do not enter a large amount of machine oil in the cylinder, the oil duct (7) that is provided with on cylinder body (8) is communicated with the through hole (4) on the cylinder liner (8), crankcase body is provided with oil nozzle (10), when piston (3) is positioned at top dead center or lower dead center, oil ring groove (13) on the piston (3) is communicated with through hole (4) on the cylinder liner (8), oil nozzle (10) is aimed at crankpin (9) hole, the end face in crankpin (9) hole has the rib that shrinks to the center, cam on the bent axle is controlled plunger-type fuel pump work fuel feeding at this moment, advance angle when plunger-type fuel pump begins fuel feeding, promptly piston (3) apart from top dead center or before bottom dead center the corner of bent axle be 30 °～40 °.Lubricant oil is by the bearing on the lubricated bent axle in the hole on the crankpin (9), offer oil groove (11) at crankcase bottom, be provided with through hole (12) in oil groove (11) bottom, one-way valve (15) is installed on through hole (12), excessive unnecessary machine oil flows to the oil groove (11) of crankcase bottom, be subjected to open from the effect one-way valve (15) of descent of piston air pressure, unnecessary machine oil is back to transmission case through oilhole (12), and one-way valve (15) prevents that the machine oil of transmission case from blowing back into crankcase and avoiding bent axle to take up excessive machine oil entering the firing chamber.
