ABSTRACT:
Working cycle for internal combustion engines, with methods and apparatuses for managing combustion charge density, temperature, pressures and turbulence (among other characteristics). At least one embodiment describes a supercharged internal combustion engine in which a supercharging portion of air is compressed, cooled and injected late in the compression process. A sub-normal compression ratio or low “effective” compression ratio initial air charge is received by a cylinder/compression chamber on the engine intake process, which during compression produces only a fraction of heat-of-compression as that produced by a conventional engine. During compression process, dense, cooled supercharging air charge is injected, adding density and turbulence above that of conventional engines with low “effective” compression ratio for this portion of air charge also. Compression continues and near piston top dead center, the air charge being mixed with fuel is ignited for power pulse followed by scavenging.
