Heat engine function
The designed and manufactured hot air machine has various structures and can utilize various energy sources and has been applied in various fields such as aerospace, land, water and underwater. The power transmission mechanism of the test hot air machine is divided into a crank connecting rod drive, a diamond drive, a swash plate or a wobble plate drive, a hydraulic drive and a free piston drive.
According to the composition of the in-cylinder circulation, the hot air machine mainly has two types of gas-filled piston type and double-action type. There are two pistons in a cylinder for regular relative movement. The cold chamber and the hot chamber are connected by a cooler, a regenerator and a heater. The gas distribution piston pushes the working medium to flow back and forth between the hot and cold chambers.
