Abstract

It is disclosed a method for operating an improved internal combustion engine. An intake valve and an exhaust valve control closing and opening of respective intake and exhaust apertures. The engine includes a separating aperture between the cylinder and a separation chamber, and a controlling separating valve. The separation chamber is connected to the intake and exhaust manifolds respectively by the intake and exhaust apertures. The method includes opening the separating valve. While it is open, the exhaust valve opens and then closes, and then the intake valve opens enabling gas flow from the intake manifold to the cylinder volume through the open intake aperture, the separation chamber and the open separating aperture. The method includes closing the intake valve and closing the separating valve. Thereby, gas flow from the intake manifold stops, isolating the separation chamber from the cylinder volume and providing double isolation during compression and combustion strokes.
