Abstract

The invention discloses an electric injection type aviation gasoline engine, which comprises a crankcase and four cylinders. The four cylinders are installed on both sides of the crankcase in pairs horizontally opposed to each other, and the air inlets of the four cylinders are all facing upwards. The air inlet of each cylinder block is connected with an EFI mechanism, and the EFI mechanism includes an intake pipe, a throttle shaft, a driving crank arm, a fuel injector, and an oil inlet pipe, and the throttle shaft passes through the radial direction of the intake pipe. Located in the middle of the intake pipe, the part where the throttle shaft is located in the inner hole of the intake pipe is fixedly connected to the throttle valve, and the end outside the intake pipe is fixedly connected to the driving crank arm, and the fuel injector is installed on the side of the intake pipe inclined to the axis of the intake pipe , the lower part of the fuel injector is equipped with a nozzle, the middle part is equipped with an electromagnetic switch valve, and the upper part is connected to the oil inlet pipe. The nozzle is located in the inner hole of the intake pipe and is located at the lower part of the throttle valve; An air filter is connected; the present invention has wide adaptability and good fuel economy.

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
