The Differential Compound Engine - Further Development

This paper introduces the development of a new idea in traction prime movers, to be known as the Differential Compound Engine. The DCE contains in addition to the compressor, an exhaust driven turbine geared into the output shaft, which leads to improved power and efficiency. It also enables the engine to operate at unchanged speed and power, regardless of output shaft speed.

This concept was designed to provide an integrated engine transmission of high output and with stepless single pedal control.
