Lubricating system for double-stroke gasoline engine

[0014] Embodiment one, such as figure 1 with figure 2 shown. The lubrication system of the two-stroke gasoline engine described in the present embodiment comprises a cylinder 1, an oil pump 9, an oil tank 7, a gear pair 10 and an oil distribution box 5, and the oil pump 9 communicates with the oil tank 7 through an oil pipe 8; the oil pump 9 The gear pair 10 is connected to the crankshaft 11 of the two-stroke gasoline engine; the oil pump 9 communicates with the oil distribution box 5 through the oil delivery pipe 6; the oil distribution box 5 is provided with four oil holes 3 on the cylinder 1 through four oil supply pipes 4, respectively Connected. The piston 2 placed in the cylinder 1 is provided with an oil ring 15 below the two gas rings 14 on its peripheral surface. When working, the crankshaft 11 of the two-stroke gasoline engine provides power to the oil pump 9 through the gear pair 10, and the oil pump 9 pumps the oil in the oil tank 7 into the oil distribution box 5

[0015] Embodiment two, such as image 3 shown. In this embodiment, the oil pump 9 and the gear pair 10 in the first embodiment are replaced by a diaphragm pump 11 . The air inlet of the diaphragm pump 11 communicates with the crankcase 13 of the two-stroke gasoline engine through the air pipe 12; 6 communicates with the oil distribution box 5. During work, the constantly changing air flow in the crankcase 13 of the two-stroke gasoline engine provides power to the diaphragm pump 11, and the diaphragm pump 11 pumps the oil in the oil tank 7 into the oil distribution box 5.
