A scroll variable cylinder methanol engine

Abstract

The invention discloses a vortex-type mutable cylinder methanol engine. The engine comprises an oil-free vortex air supply mechanism, a vane wheel engine mechanism, a burning spray mechanism, a vane wheel mechanism and a cooling mechanism, wherein the oil-free vortex air supply mechanism is provided with an oil-free vortex compressor 3, the front end of a vortex compressor air inlet 5 of the vortex compressor 3 is provided with a turbocharger 21, and the burning spray mechanism is provided with a burning spray chamber 16; a dual-purpose motor 11 is provided with a high-pressure methanol pump 7, the high-pressure methanol pump 7 is provided with a high-pressure methanol nozzle 13, and the vane wheel mechanism is provided with a main shaft 31; a main engine self-cooling wind wheel 28, a vane wheel 32 and an oil-free bearing 27. The vortex-type mutable cylinder methanol engine has the technical effects that compressed gas is provided for the engine by virtue of the oil-free vortex compressor, and the air supply pressure of the oil-free vortex compressor is increased by virtue of the turbocharger which is capable of utilizing tail gas energy, so that the air-fuel ratio is improved; the vane wheel with a sealing section function is adopted, so that the capacity torque is increased; the igniter directly jets thrust to the vane wheel, so that the fuel is saved, the controllability is improved, and requirements for human travel and health are met.

Description

technical field [0001] The invention relates to an engine, in particular to a scroll type variable cylinder methanol engine. Background technique [0002] Gasoline and diesel engines currently in use convert linear motion into circular motion through the crankshaft to do work, which includes a crankshaft mechanism with a relatively short torque, rotary compression, many wearing parts, and high heat generation. It must be equipped with an oil cooling mechanism. Water-cooling mechanism and air-cooling mechanism have complex combination, large volume, large operation vibration, low power-to-weight ratio, use of disposable fuel, and face the oil crisis, do not make full use of the energy advantages of domestic methanol production capacity, heavy pollution, and high operating costs . Contents of the invention [0003] Aiming at the above problems, the present invention provides a scroll-type variable-cylinder methanol engine with simple structure, good power controllability, h...
