Electric spraying type aviation gasoline engine

Abstract

The invention discloses an electric spraying type aviation gasoline engine, which comprises a crankcase and four cylinder bodies, wherein the two cylinder bodies are arranged at two sides of the crankcase in pairwise parallel opposite arrangement, an air inlet of each of the four cylinder bodies is in upward arrangement, an electric spraying mechanism is connected onto the air inlet of each cylinder body, each electric spraying mechanism comprises an air inlet pipe, a throttle valve rotating shaft, a driving crank arm, an oil sprayer and an oil pipe, the throttle valve rotating shaft is arranged in the middle part of the air inlet pipe in the radial direction of the air inlet pipe in a penetrating way, the part, positioned in an inner hole of the air inlet pipe, of the throttle valve rotating shaft is fixedly connected with a throttle valve, one end, positioned outside the air inlet pipe, of the throttle valve rotating shaft is fixedly connected with the driving crank arm, the oil sprayer is arranged at the side surface of the air inlet pipe in a way of being inclined to the axial line of the air inlet pipe, the lower part of the oil sprayer is provided with a spray nozzle, the middle part of the oil sprayer is provided with an electromagnetic switch valve, the upper part of the oil sprayer is connected with the oil inlet pipe, the spray nozzle is positioned in the inner hole of the air inlet pipe and the lower part of the throttle valve, the lower part of the air inlet pipe is fixedly connected with a flange, and the upper part of the air inlet pipe is connected with an air filter. The electric spraying type aviation gasoline engine has the advantages that the application range is wider, and the fuel oil economical performance is better.

Description

technical field [0001] The invention relates to the technical field of manufacturing aviation gasoline engines, in particular to an electronic injection type aviation gasoline engine. Background technique [0002] The mechanism that the existing aviation two-stroke gasoline engine provides the mixed gas to the cylinder is a carburetor. Although the technology of this kind of mechanism that uses the carburetor to provide the mixed gas is relatively mature, its problem is that the fuel economy is poor. In high-altitude areas, because the air is relatively thin, it is difficult for the carburetor to provide a precise concentration of mixed gas to the cylinders of the engine, and it is difficult for the engine to work normally. Therefore, it is difficult for this traditional aviation two-stroke gasoline engine to be used in high-altitude areas. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an electric injection typ...
