Regenerative Supercharging of Four Stroke Internal Combustion Engines

A regenerative supercharging method has been studied and shows an improvement in four stroke engine performance. With this method the mechanical or pneumatic connection between the engine and the supercharger is removed and replaced by a thermal connection. The heat from the engine is converted into compression work by means of a suitable R.S. cycle and this process leads to an increase in power and efficiency.

Regenerative supercharging has been compared with traditional turbocharging and the results arc presented for some kinds of engines.
