Abstract
An internal combustion engine operating generally in accordance with a thermodynamic cycle called the General Cycle, achieving maximum efficiency with limited pressure and temperature, and having an expansion ratio R, a compression ratio Rand an Atkinson ratio A. The Atkinson ratio is in the range from 1.1 to 1.8, the expansion ratio is in the range from 22 to 50, and the compression ratio is in the range from 20 to 36. Given engine parameters, an optimum efficiency R-Rpair can be determined. The engine may include a high ratio of stroke length to bore, or may be of an opposed piston construction.
