Abstract
A turbo-charged internal combustion cylinder assembly includes a combustion chamber, an intake port communicably connected with an intake manifold, and an exhaust port communicably connected with an exhaust manifold. An intake valve is disposed within the intake port, and an exhaust valve is disposed within the exhaust port, the valves facilitating, in an open position, or restricting, in a closed position, gas flow between their respective ports and the combustion chamber. A compressor may be communicably connected to the intake manifold so as to provide pre-combustion gases to, and regulate pressure of the combustion chamber. The exhaust valve may open while the intake valve is closed to exhaust post-combustion gases from the combustion chamber. Alternatively, the exhaust valve may open while the intake valve is open to admit post-combustion gases into the combustion chamber if the combustion chamber pressure is lower than the exhaust port pressure.
