U.S. Patent Specifications

Abstract

The improved method of operating an internal combustion engine which includes the steps of precompressing a gas for subsequent further compression in the engine, to a precompressed super‐atmospheric pressure substantially the same as that from which net cylinder compression is to be initiated, cooling the precompressed gas, introducing the precompressed and cooled gas from a common source into all or a group of the engine cylinders at substantially constant pressure, limiting the volume of the gaseous charge confined on any one cylinder for net compression therein to substantially less than the volumetric capacity of the cylinder, compressing the confined charge through a selected compression ratio in the cylinder for ignition therein and expanding the ignited charge in the cylinder through an expansion ratio substantially greater than said selected compression ratio.
