Totally-changeable intake and exhaust mechanism of compressed air engine and method of mechanism

Abstract

The invention discloses a totally-changeable intake and exhaust mechanism of a compressed air engine and a method of the mechanism. A cylinder cover is arranged on a cylinder wall. An intake valve and an exhaust valve are arranged inside the cylinder cover. The intake valve and the exhaust valve are connected with an air storage tank through an intake and exhaust channel. Throttling valves are arranged on the inner layers of the intake valve and the exhaust valve in a sleeving manner. The throttling valves are driven by a throttling valve driving mechanism. The intake valve and the exhaust valve are driven by an intake and exhaust power transmission mechanism. A piston is arranged inside the cylinder wall. A compressed air one-way valve, an air cylinder intake one-way valve and a combustion chamber of the compressed air engine are connected. Totally-changeable intake and exhaust of the pneumatic engine can be achieved, and the intake and exhaust duration time and the maximum valve opening can be adjusted by adjusting the throttling valves, so that the working state of the engine is adjusted according to the requirement of working conditions. Meanwhile, the engine can be switched between the braking energy recovery working manner and the pneumatic driving manner by adjusting the positions of the throttling valves and controlling the one-way valves.

Description

technical field [0001] The invention belongs to the field of new energy engines, and relates to a fully variable intake and exhaust mechanism of a compressed air engine and a method thereof, which can provide high-pressure compressed air for the compressed air engine. Background technique [0002] As the two problems of energy shortage and environmental pollution facing the world today have gradually attracted the attention of the whole world, the automobile industry has also focused its attention on the research of new energy vehicles. Today's new energy vehicles are developing rapidly, such as electric energy storage, hydraulic energy storage, flywheel energy storage, etc. Among them, electric vehicles are already active in the streets and alleys. Now, pneumatic vehicles powered by high-pressure compressed air have also come into people's field of vision. [0003] Air motors consume no fossil fuels and thus have zero carbon emissions. Since the power source of the engine...
