Abstract: In a method for operating an internal combustion engine, as a function of a desired load, wherein a desired pressure in the intake pipe of the internal combustion engine is determined and set by means of an air supply device, the ignition timing, the beginning of fuel injection and the duration of fuel injection values are determined in accordance with a predetermined relationship as a function of the desired load and the values are supplied as actuating signals to actuating elements by which the ignition and the fuel injection are adjusted to improve the engine response behavior.

Abstract: In a method of operating an internal combustion engine which has at least two cylinder banks that can be controlled separately as a function of a desired load, wherein a desired pressure in the intake pipe of the internal combustion engine is determined and set by means of an air supply device for supplying combustion air to the cylinders of the internal combustion engine, at least one engine-related characteristic value which affects the behavior of the internal combustion engine is determined for each cylinder bank, and, in the event of a difference between the characteristic values of the cylinder banks, at least one cylinder bank is manipulated in such a way that the average value of the considered characteristic quantity corresponds to a desired average value in order to reduce the thermodynamic and mechanical loading of the internal combustion engine with bank-selective operating mode.

Abstract: In a method for the operation of an internal combustion engine either on all cylinders (as full engine) or with only some cylinders in operation (cylinder cut-off), the cylinders are divided, in the firing order, into two groups of alternating cylinders which are selectively operative with an angular ignition spacing twice that of the cylinders of the engine when operating as full engine, the two groups of cylinders being activated alternately during engine operation with cylinder cut-off.

Abstract: A method for adjusting an internal combustion engine with variable valve timing wherein the current position of the accelerator pedal is associated with a set air mass and a set pressure. The set pressure is compared with a reference pressure and control of the set air mass takes place via the throttling device in the intake pipe when the pressure falls below the reference pressure, and control of the set air mass is carried out via the engine valves when the pressure exceeds the reference pressure.

Abstract: In a motor control method and apparatus for an internal combustion engine, a point for the beginning of injection moment and injection period for each cylinder are determined in a load-controlled way in a motor controller and supplied to the actuators for execution of the injection. To improve the response characteristic of the internal combustion engine, control information for injection of the cylinder currently to be addressed is transmitted as reserve information for the subsequent cylinder in every transmission cycle. In the event of a load increase, reserve information from the previous transmission cycle is used to control injection in the subsequent cylinder.

Abstract: The invention provides a device for determining the engine load for an internal combustion engine, such device having an input channel for receiving an item of engine speed information, as well as an intake manifold pressure sensor and an air mass flow rate sensor arranged upstream of a throttle valve, and/or a throttle valve angle sensor. The engine speed is fed to a Kalman filter as an input value and at least one of the three variables intake manifold pressure, throttle-valve air mass flow rate and throttle valve angle is fed as a variable measured by the respective sensor. The Kalman filter derives estimated values for the variables intake manifold pressure and throttle-valve air mass flow rate, with which the air mass flowing into a respective cylinder of the engine per working cycle is determined.
