The performance of the external combustion heat engine is improved by the fact that the combustion gas and the excess of burnt air are carried into a turbine (24). Both the combustion gas and the burnt air expand through the turbine, before being rejected to the atmosphere. The burnt air exhaust from a heat exchanger (4). This process takes place at a temperature and pressure, which are higher than those of the atmosphere. The turbine is used to drive an air compressor (25). The output form this compressor is used, primarily, as the principal drive for the inlet to the engine. An adjustable fraction of the compressed air. It is adjustable by a valve (33), which may be diverted through an exhaust heater (29) and to the burner (27) to act as the combustible air for the inlet.
