Internal combustion engine with stratification of the exhaust gas recycle connections and advantages of the stratification

摘要

The engine has a cylinder (2) disposed on the top of a cylinder head for defining a combustion chamber (5). Air and fuel mixture is supplied to the cylinder through an inlet pipe. Gases from the combustion chamber are conveyed by an exhaust pipe (8) and closed by an exhaust valve (9). An injection unit (10) and a nozzle (11) are placed in the cylinder head for injecting recycled exhaust gases into the cylinder. An independent claim is also included for a process of stratifying exhaust gas in a combustion chamber of an internal combustion engine.
