Embodiment Construction

[0019] specific implementation plan

[0020] The present invention is described below in conjunction with embodiment.

[0021] like figure 1 As shown, the piston pneumatic engine system mainly consists of a high-pressure gas tank, a manual regulating valve, a buffer tank, an electronic control unit, an electronically controlled regulating valve, and an engine.

[0022] The high-pressure air storage tank adopts a carbon fiber fully wound air tank to store air with a maximum pressure of 35MPa. When used in a small scooter, two 80L gas tanks can be connected in parallel.

[0023] The buffer tank adopts a general steel cylinder with a volume of 5L. Control the pressure of the gas entering the buffer tank by adjusting the manual regulating valve, usually set to 2MPa.

[0024] The electronic control unit reads the signal of the accelerator pedal of the engine, and then controls the opening of the electronic control valve, and then controls the output power of the engine.

Abstract

The invention provides a piston type air-powered engine system capable of providing power for a vehicle, an engineering machine, a power generation device and the like and belongs to the field of power machinery. The piston type air-powered engine system utilizes gas stored in a high-pressure gas tank, and the gas is buffered and then is fed into an air cylinder through a gas distribution mechanism to push a piston to do work. Compared with a piston type internal combustion engine, a piston type air-powered engine is stable in working doing process and small in noise. The piston type air-powered engine is a two-stroke engine, namely adopts an intake work-doing stroke and an exhaust stroke, the operation process of the piston type air-powered engine is mainly a compressed gas expansion work-doing process and is a physical change process, and no exhaust pollution exists.

Description

technical field [0001] The invention belongs to the field of power machinery and relates to a piston type pneumatic engine system. Background technique [0002] With the widespread use of piston internal combustion engines (including diesel engines, gasoline engines, natural engine engines, etc.) on vehicles, the air pollution in cities has become increasingly serious. And the internal combustion engine also consumes non-renewable fossil energy. [0003] Gasoline-electric hybrid and pure electric are solutions that have emerged in recent years to replace traditional internal combustion engines, but gasoline-electric hybrid and pure electric have brought pollution problems caused by waste batteries. [0004] The piston-type pneumatic engine system realized by the present invention uses high-pressure gas (usually high-pressure air) as the energy source, and does not discharge any pollutants during its working process. At the same time, there is no pollution problem in the pro...
