Abstract
An engine and method for achieving superior operational benefits by application of the General Cycle for heat engines. A two-stroke internal combustion engine having an Atkinson ratio A and a compression ratio RC, the compression ratio having a value in the range from 19 to 30, and an Atkinson ratio selected such that the product of Atkinson ratio and compression ratio is near to and generally greater than 36. The best values of this product, ARC, vary slightly with the choice of compression ratio according to the following relationship: ARC≥36.33+8788e−0.375Rc.The engine includes a conventional exhaust valve and may include a high ratio of stroke length to bore, or may be of an opposed piston construction.
