Hot air engine

Abstract

A heat engine consists of one to four groups of cylinder bodies and corresponding pistons, a crank shaft, a heater, a regenerator and a cooler, which can be of gas distribution type or of double acting type, wherein, the piston and the crank shaft inside the cylinder body are a two-link and combined locking-releasing mechanism; the clearance between the piston and the sidewall of the cylinder body is provided with pressure gas for forming a thin gas layer, thus being easy to work in relatively low thermal parameters.

Description

[0001] The invention relates to a heat engine, in particular to a heat engine whose piston and crankshaft are connected by two connecting rods and a lock-release mechanism. Background technique: [0002] Most of the traditional heat engines use an inertial system to drive the piston movement through the double-ring mechanism or the crankshaft mechanism to complete the thermodynamic cycle (CN1217765A). The disadvantage is that the actual working cycle is difficult to approach the theoretical cycle, and it needs to be operated under high temperature and high pressure conditions. This again brings about the problem of difficult sealing. CN2315306Y discloses a scheme for driving the movement of the gas distribution piston by an elastic turning mechanism, so that the actual working cycle is closer to the theoretical cycle, but the actual cycle is affected by the spring parameters, which is difficult to adjust, and the lateral force is difficult to balance, especially When the pisto...

CN2315306Y discloses a scheme for driving the movement of the gas distribution piston by an elastic turning mechanism, so that the actual working cycle is closer to the theoretical cycle, but the actual cycle is affected by the spring parameters, which is difficult to adjust, and the lateral force is difficult to balance, especially When the piston is in the spring flip position, the friction between the gas distribution piston and the cylinder wall will increase due to the large lateral force, which will affect the movement of the piston and increase the wear due to friction
