Abstract
A hot gas engine including an injector for introducing a mixture of air and fuel into the combustion chamber to heat the working medium which is circulated in a system of ducts. Fresh air for the combustion of the fuel is preheated in a heat exchanger by exhaust gases from the combustion chamber and conducted to the fuel injector. A heating system for passing a heat exchange fluid to a space to be heated surrounds the combustion chamber, and the heat exchange fluid is thus heated by heat exchange with the exhaust gases.
