Abstract

PURPOSE:To improve engine efficiency, in a 4-cycle internal combustion engine, by providing an intake valve, closed in the first half of an intake stroke, and an exhaust valve, opened for a short time from an end of the intake stroke to the beginning of a compression stroke. CONSTITUTION:An internal combustion engine comprises a two-stage supercharger constituted by exhaust turbines 1 and compressors 2. An intake valve 4 is closed in the first half of an intake stroke, and a supplied mixture is expanded while removing heat from the top part of a piston 6 and the internal wall of a cylinder at high temperature, accordingly, the piston is depressed to generate power. Further an exhaust valve 5 is opened for a short time from an end of the intake stroke to the beginning of a compression stroke, and a surplus amount of air is relieved, accordingly energy of consumption can be saved at the compression stroke.
