Abstract: In a method of controlling adjustable operating parameters of an internal combustion engine with direct fuel injection which includes at least one cylinder having a piston delimiting a combustion chamber, a fuel injector and a spark plug, wherein air supplied to the combustion chamber through an air intake passage forms with the fuel injected by the fuel injector a fuel/air mixture which is compressed and produces a plasma cloud which is then ignited by a spark generated between the electrodes of the spark plug, the ionization degree of the plasma cloud is measured and an ionization signal is formed and supplied to an electronic control unit where it is utilized to control at least one operating parameter of the internal combustion engine.

Abstract: An internal-combustion engine includes an engine control system that permits a change-over between a lean operation and a rich operation of the internal-combustion engine, and an exhaust gas purification system. A &lgr;-probe, an SOx storage catalyst and an NOx storage catalyst are successively arranged in an exhaust gas line behind the engine. At the start of desulfurization of the SOx storage catalyst, a change-over takes place from the lean to the rich operation of the engine. Secondary air is fed into the exhaust gas line; a predetermined &lgr; value of the exhaust gases mixed with secondary air and a temperature in the SOx storage catalyst are measured. At the end of the desulfurization, a change-over takes place from the rich to a lean operation of the engine.

Abstract: In a method for the periodic desulphurization of a nitrogen-oxide or sulphur-oxide accumulator of an exhaust-gas cleaning system of an internal-combustion engine, during respective desulphurization periods, the accumulator is fed secondary air by secondary-air supply means, and is fed an engine exhaust gas which contains a reducing agent by setting a rich engine air ratio. At least during part of the desulphurization period, after a predeterminable desulphurization temperature has been reached, the accumulator air ratio is set, by suitably alternating the secondary air quantity supplied and/or the engine air ratio, between an oxidizing or stoichiometric atmosphere, and a reducing atmosphere.
