Abstract: Cylinder deactivation is a proven solution to improve engine fuel efficiency. The present invention is related to Dynamic Cylinder Deactivation (DCD) solution to conventional internal combustion engine. DCD is an energy saving method based on engine thermodynamics and residual heat recovery. It deactivates all the cylinders within the engine alternatively and dynamically, totally different from traditional sealed-valves cylinder deactivation solutions. DCD has many advantages over traditional sealed-valves cylinder deactivation. Thermodynamic efficiency gain, residual heat recovery, high Lambda and “Air-Hybrid” are the most attractive features of DCD. DCD also makes engine displacement variable.
