Abstract
A spark ignited internal combustion engine includes a main combustion chamber, an auxiliary combustion chamber connected to the main combustion chamber, and fuel delivery means for supplying separate partial quantities of fuel to the main combustion chamber and auxiliary combustion chamber. Since the auxiliary combustion chamber is maintained at an elevated operating temperature and the partial quantity of fuel delivered to the auxiliary combustion chamber is an easily dissociable fuel, thermal dissociation of the easily dissociable fuel may occur prior to ignition.
