UW-Madison engineer collaborating with entrepreneur on 6-cycle, external combustion engine; could be up to 30% more efficient than standard diesel

Green Car Congress

The K6 engine uses six strokes instead of four to reduce the pressure of exhaust gases, which allows it to harvest more energy rather than expelling it with the gas. So when you open the exhaust valve to dump expanded gas out to the environment, you lose all of that energy stored in the high-pressure exhaust gases and you create a lot of noise. Shedd said the engine could be up to about 30% more efficient than a standard diesel engine, depending on the engine load and speed.
