[0001] The present application relates to the technical field of engine, in particular to a tilting engine. BACKGROUND

[0002] The previous single cylinder engine is provided with a balance block shaft matched with the crank shaft through a gear to offset the vibration caused by the rotation of the crank shaft. The balance device is just arranged below the crank shaft, so that they are immersed in the lubricating oil in the oil pool formed by the inner bottom of the crank housing, and the oil is ignited according to the rotation of them, so as to increase the temperature of the lubricating oil. Moreover, the speed of the balance device is reduced or constrained by the resistance of the ignited oil. If the single cylinder is arranged in a tilting manner, the balance device arranged on the extension line of the cylinder body axis intersecting with the crank shaft is separated from the bottom of the crank housing by a high enough distance, so as to be arranged above the lubricating oil pool without sinking into it.

[0011] Preferably, the method for using the inclined engine is as follows:

[0012] The crank housing 10 is fixed at an angle of 18° with the vertical angle;

[0013] When the piston is driven to slide in the piston sleeve by the connecting rod, the sealing ring arranged on the piston is tightly attached to the inner wall of the piston sleeve, so that the sealing property of the piston sliding in the piston sleeve is ensured; after the sealing ring is worn, the oil medium in the piston sleeve enters the groove from the interiors of the through holes and the through grooves, and the sealing ring is pushed outwards by the oil medium, and meanwhile, the worn part of the sealing ring is supplemented by the spring arranged in the groove.

[0014] The present application provides an inclined engine.
