Combustion and Exhaust Emission of an Engine Using the Porsche-Stratified-Charge-Chamber-System 750888

The development of vehicle combustion engines today is characterized by the effort to reduce exhaust gas emission and fuel consumption and to conserve the good properties of the combustion engine at the same time. As, at least for the years to come, there will be no chance for the utilization of the alternative special drives, PORSCHE is intensely dealing with the further development of the conventional combustion engine as well as of the stratified-charge-chamber engine. With their stratified-charge engine (SKS) PORSCHE has tried to create optimum conditions for each of the combustion phases. The result was a divided combustion chamber with a three-stage combustion. The system was tried on single-, six-, and eight-cylinder engines and led to good results under stationary conditions on the testing rig as well as under unstationary driving conditions.
