Novel gasoline engine

The utility model relates to a novel gasoline motor which can reduce frictional resistance and the heat load of a motor piston. The utility model comprises a motor integral structure, a main oil passage of an air cylinder body in the integral structure and a piston. The utility model has the technical scheme that piston cooling nozzles which can make oil bundle inject on the surface of the inner chamber of the piston are uniformly arranged on the main oil passage of an air cylinder body. The utility model has the advantages that the average effective pressure of the motor is increased by increasing the compression ratio of the motor, the thermal efficiency of the motor is increased by optimizing air charging and the economic performance of fuel oil of the motor is increased. The piston cooling nozzles are additionally arranged on the main oil passage of an air cylinder, fast cooling can be carried out to the inner chamber of the motor piston by lubricating oil and the heat load of the motor piston is reduced. A cooling jetting hole of a connecting rod big end is simultaneously canceled, the carrying capacity of the connecting rod bearing is reinforced, the tile grinding probability of the connecting rod bearing is reduced and the reliability of the motor is increased. The frictional resistance of the motor main body is reduced after the bearing width of part bearing of the motor is reduced, and the output power of the motor is increased.
