Abstract
A method for improving the efficiency of an internal combustion engine changes the volume in a piston chamber of an expander device. The expander device generally operates at a fixed expander device speed to perform work on a swash plate expander shaft. The swash plate expander shaft is connected to a first end of a piston in the piston chamber.

A method for improving the efficiency of an internal combustion engine, comprising:
- changing the volume in a piston chamber of an expander device having a fixed expander device speed to make the expander device perform work on a swash plate expander shaft connected to a first end of a piston on said piston chamber.
A positive displacement expander device, comprising:
- a piston chamber;
- a piston located within said piston chamber;
- a piston inlet chamber opening located in said piston chamber;
- and
- an expander shaft connected to both a swash plate connected to said piston and a rotating inlet disk,
- wherein said rotating inlet disk has an inlet port selectively matched with said piston inlet chamber opening and an outlet port selectively matched with said piston chamber inlet chamber opening.
