Gas axial transmission alpha type four-cylinder double-acting stirling engine

Abstract

The invention discloses a gas axial transmission alpha type four-cylinder double-acting stirling engine which comprises a combustion device; a heating device is arranged indie the combustion device; an air cylinder top of a working medium circulating device is connected with the heating device; an air cylinder at one end of the working medium circulating device is connected with the corresponding cooling device; the heating device and the cooling devices are connected through heat regenerators to form a closed working medium circulating loop; a transmission device is connected with a piston rod of the working medium circulating device through a connecting rod; the transmission device and the combustion device are connected by a split casing to form a whole; by taking ammonia or helium as a working medium and adopting a positive sterling cycle, the working medium absorbs heat from the combustion device, stores energy through the heat regenerators and discharges heat to the cooling devices, thereby forming a complete working medium circulating loop; and a transmission mechanism outputs shaft work to the outside. The gas axial transmission alpha type four-cylinder double-acting stirling engine disclosed by the invention has the advantages of cleanness, high efficiency and low noise; and in addition, the service life of a sealing element of the engine can be longer.

Description

technical field [0001] The invention belongs to the technical field of Stirling engines, in particular to a gas-type axial transmission A-type four-cylinder double-acting Stirling engine. Background technique [0002] With the increasingly severe energy and environmental situation, energy conservation and environmental protection are the primary goals in many fields. Automobiles are currently an important source of urban environmental pollution. Therefore, in the development strategy formulated by the country, automobile energy-saving and emission-reduction technologies are taken as an important content. It is urgent to find an energy-saving and environment-friendly solution. The Stirling engine using natural gas as fuel is a new type of engine with a novel structure. It was developed after the traditional internal combustion engine caused the shortage of oil energy and the increasingly serious environmental pollution. The emission of the new gas-fired Stirling engine Low e...

AI Technical Summary

Problems solved by technology

The current Stirling engine scheme mostly adopts the swash plate transmission scheme, which has a large output torque and relatively mature related technologies, but the piston bears a large radial force, while the piston of the Stirling engine is lubricated without oil, and the piston Bearing a large radial force is not good for improving engine life

And the existing Stirling engine mostly adopts gasoline and diesel oil as fuel, which also causes serious environmental pollution.
