摘要： The invention relates to a method for the cylinder-selective control of an air/fuel mixture to be burnt in a multi-cylinder internal combustion engine, in which the lambda values for different cylinders or groups of cylinders are separately sensed and controlled, and also relates to a multi-cylinder internal engine suitable for carrying out the method. In accordance with the invention, the lambda values of the individual cylinders or groups of cylinders are simultaneously controlled to different required values using an integrating I-control proportion with variable integrator slope and/or a differentiating D-control proportion.

摘要： With an internal combustion engine (1) there is the problem that the fuel-air mixture directed into the combustion chamber of the cylinders (2) can be substantially influenced by manufacturing tolerances and ageing of the fuel injectors and uneven distribution is thus created. The uneven distribution is individually determined for each cylinder (2) depending on the operating mode of the internal combustion engine (1) (homogenous operation, stratified operation), wherein either the exhaust gas is analyzed and a corresponding emission value is determined therefrom or that a value is individually determined for each cylinder (2) for the operational roughness of the internal combustion engine (1). These values are compared with a limit value predetermined for the internal combustion engine (1) and upon exceeding of the predetermined limit value a fault entry in a fault memory (9) is made for the cylinder (2) concerned.

摘要： By a respective cylinder-specific lambda regulator, a regulator value for influencing the air/fuel ratio in the respective cylinder is determined as a function of the cylinder-specific air/fuel ratio measured for the respective cylinder. The regulator value is monitored for the attainment of a first predefined threshold value, and when the latter is reached, a lambda quality value is determined which is representative of the deviation of the measured cylinder-specific air/fuel ratios assigned to the respective cylinders. The regulator value is monitored for the attainment of a second predefined threshold value which is representative of a more pronounced regulating intervention than the first threshold value. When the second predefined threshold value is reached, the lambda quality value is determined. If the lambda quality value assigned to the first threshold value is lower than the value assigned to the second threshold value, unstable regulating behaviour is identified. Stable regulating behaviour is identified otherwise.

摘要： Injectors each having a piezo actuator are assigned to cylinders of an internal combustion engine. A regulator device is configured for furnishing a cylinder-specific controlled variable and a command variable to a controller whose primary manipulated variable is a variable representing an electrical power supplied to the piezo actuator during a control cycle. A manipulated variable splitting unit is provided whose input variable is a regulator-determined regulator value of the primary manipulated variable and is configured for determining a total value of the primary manipulated variable according to the regulator value. It is also configured for splitting the total value into a primary value of the primary manipulated variable and into a secondary value of a secondary manipulated variable according to a lower and/or upper threshold value of the total value.

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 a controller. The predefined crankshaft angle is adapted according to an instability criterion of the controller.
