In a revolving piston device that is used to make a four stroke internal combustion engine, revolving piston pairs (22, 23, 24, 25) are made to complete two cycles of one compression phase and one expansion phase each. The openings (2-7, 10-17, 34-36) on components of revolving piston device are made in such a way that an opening can be used for multiple flow passages to reduce unutilised space within controlled active volume that reduces unutilised expansion of gases or air within controlled active volume during respective power stroke. This also reduces loss of fresh gases trapped within the openings to exhaust manifold. This invention describes how to use same opening on various components of a revolving piston device for multiple flow passages to reduce overall losses.
