ABSTRACT:
A screw engine for propelling a wheeled vehicle via a continuously variable transmission is characterized by a ceramic screw compressor and a ceramic screw expander mounted on a common shaft of the continuously variable transmission. The compressor compresses air and delivers it to a combustion chamber. The air is mixed with fuel in the chamber and ignited to produce combustion products. The combustion products are expanded by the expander to produce a work output for driving the continuously variable transmission and an exhaust output. A heat exchanger is connected with the expander to recover heat from the exhaust output.
