ABSTRACT:
A method for operating an internal combustion engine in controlled self-ignition, a fuel-air mixture being introduced into a combustion chamber at least partially in a gas-exchange cycle, and being compressed in a compression stroke, the load range usable for the Otto engine self-ignition is broadened in that, in the fuel-air mixture, during the gas-exchange cycle, a flame front is generated at one or a plurality of places by spark ignition, which compresses and/or heats up the remaining fuel-air mixture, and converts the latter thereby at least partially to intermediate combustion products.
