摘要： The invention relates to a method for regulating the lambda value of an internal combustion engine with a catalytic converter for subsequently treating the exhaust gases of the internal combustion engine, with a binary lambda probe, which is mounted upstream from the catalytic converter and which senses the composition of the exhaust gases. According to the invention, the lambda set value is superimposed with a lean/rich amplitude. This lean/rich amplitude has an integral component and a discontinuous component leading back to the lambda set value. When a change that differs from the change in the exhaust gas composition caused by the lean/rich amplitude is detected, the coefficient of the integral component is modified and/or a discontinuous component is added to the integral component or subtracted therefrom.

摘要： In order to control an internal combustion engine, a fuel mass that is to be supplied to the respective cylinder is determined according to a load variable. An additional fuel mass to be measured once is determined, when the measuring signal of an oxygen probe arranged downstream from a three-way catalytic converter is characteristic of at least one pre-determined residual oxygen part, according to the course of the measuring signal. A once reduced fuel mass is determined, when the measuring signal is characteristic of at least one pre-determined residual fuel part, according to the course of the measuring signal. A corrected fuel mass to be measured is determined according to the fuel mass to be supplied and optionally less the once reduced fuel mass or the fuel mass to be measured once. An actuating signal for controlling the injection valve is generated according to the corrected fuel mass to be supplied.

摘要： Method for lambda control in an internal combustion engine with a catalytic converter in an exhaust tract and at least one lambda probe mounted inside the catalytic converter. With this arrangement of the upstream probe there are signal delays which slow down the lambda control. To compensate, the measurement signals from the first lambda probe are applied to a lambda analysis unit which corrects measurement signal delays, and the corrected lambda probe signal is applied to a unit for lambda control. Both lambda probes are connected to a unit for lambda control.

摘要： A device is designed for determining a pre-set air/fuel ratio in the combustion chamber of a cylinder of an internal combustion engine. The device is further designed for determining a filtered, pre-set air/fuel ratio in the combustion chamber of the cylinder by filtering the pre-set air/fuel ratio in the combustion chamber of the cylinder by means of a filter which models the dynamic behavior of the upstream region of the exhaust gas catalyst relative to the arrangement of the exhaust gas probe in the exhaust gas catalyst, in particular its storage, reduction and/or oxidation properties. The device is further designed for determining an adjustable variable by means of a regulator as a function of the filtered and pre-set air/fuel ratio, and of a sensed air/fuel ratio in the combustion chamber of the cylinder.

摘要： The invention relates to a waste gas probe which is disposed in an internal combustion engine, comprising a plurality of cylinders and injection valves associated with the cylinders, in order to measure fuel. The waste gas probe is arranged in a waste gas tract and the measuring signal thereof is characteristic for the air/fuel ratio in the respective cylinder. The measuring signal is detected in relation to a reference position of the piston of the respective cylinder at a predefined crankshaft angle and associated with a respective cylinder. A manipulated variable which is used to influence the air/fuel ration in the respective cylinder according to the measuring signal detected for the respective cylinder is produced by means of a controller. The predefined crankshaft angle is adapted according to an instability criterion of the controller.
