    摘要： An electronic engine control system for an internal-combustion engine has a computer with programs stored therein and interacts with a sensor system to determine a residual gas fraction in a combustion space of the engine. The engine control system generates a signal value, which correlates with the current residual gas fraction, from a signal value which is generated by the engine control system and which correlates with a current air/fuel mass ratio of a carbureted fuel fed to the combustion space, and from a signal value which is sensed by the sensor system and which correlates with a current air/fuel mass ratio of an exhaust gas discharged from the combustion space after the combustion.

    摘要： A process operates a piston engine in which at least one intake valve and at least one exhaust valve are assigned to each of the cylinders of the piston engine. The piston engine is equipped with a valve actuator permitting variable opening and closing times. An engine control system of the piston engine determines a current actual value of an exhaust gas mass proportion. The value forms the contents of the cylinders together with a fresh gas mass proportion after the fresh gas has been supplied and before combustion. The engine control system actuates the valve actuator in order to set a desired value for the exhaust gas mass proportion.

    摘要： A direct-injection Otto cycle internal-combustion engines can be operated in the stratified charge mode with a later fuel injection during the compression cycle and a lean mixture formation and, with an operating mode with a homogeneous mixture formation, by fuel injection during the intake cycle which is provided for higher load ranges of the internal-combustion engine. The exhaust gases of the internal-combustion engine are decontaminated by an NOx storage catalyst which must be periodically regenerated during a homogeneous mixture formation and at rich fuel/air ratios (&lgr;). To permit a fast change of the operating mode and particularly the regeneration of the storage catalyst without changing the running performance of the internal-combustion engine, the fuel quantity to be injected per power cycle, is apportioned during a homogeneous operating phase during the change of operating modes, corresponding to the actual intake air flow rate by adjusting the respective injection time. Isochronously and proportionally to the change of the injection time, the ignition point in time is adjusted in the direction of a late ignition. The homogeneous operating phase is limited by a change-over point in time at which the injection end of the fuel injection is shifted into the power cycle provided for the demanded operating mode.
