摘要： An injection-pressure setpoint value for the pressure accumulator of an accumulator injection system is specified as a function of the operating point of the engine. The setpoint is specified with the aid of respectively separate characteristic diagrams for the start, idling and load engine operating states. In load operation, the profile of the injection-pressure setpoint value is additionally adapted to the particular requirements of the transient engine operation with a first timing element whose timing characteristics depend on the engine speed. The profile may be briefly raised out of a low engine speed in the case of an acceleration. With the aid of a downstream, second timing element which is independent of the first timing element, sudden transitions in the specification of the setpoint values when the engine operating state changes are suitably smoothed out. Any jumps in the injection-pressure setpoint value are avoided. The gear which has been engaged or the driving style of the driver can be taken into account in the transfer characteristics of the second timing element.

摘要： A method for monitoring a pressure sensor, which determines a pressure in a pressure accumulator regulated by a pressure actuator, includes the steps of calculating an expected pressure value in the pressure accumulator for a given point in time based on a holding pressure preset by the pressure actuator and based on a detected rate of change in a mass balance of a medium contained in the pressure accumulator. A pressure value in the pressure accumulator is determined with the pressure sensor at the given point in time. The expected pressure value is compared with the determined pressure value and a malfunction in the pressure sensor is detected if the pressure values deviate from each other beyond a predetermined value. A device for monitoring a pressure sensor is also provided.

摘要： An internal combustion engine has an intake tract, at least one cylinder, an exhaust gas tract and inlet and outlet valves, which are assigned to the cylinder. An exhaust gas pressure in the cylinder is determined during the valve overlap of the inlet and outlet valves as a function of an estimated value of an exhaust gas pressure, which is effected by the combustion of an air/fuel mixture in the cylinder, and a variable which characterizes the centroid of the valve overlap of the inlet and outlet valves. At least one actuating signal for controlling an actuator of the internal combustion engine is derived from the exhaust gas pressure, or the internal combustion engine is monitored as a function of the exhaust gas pressure.

摘要： An internal combustion engine has a plurality of cylinders to which in each case at least one inlet valve and one outlet valve are assigned. A valve drive is assigned for controlling the inlet valve and a valve drive is assigned for controlling the outlet valve. The valve control time for the inlet valve of a cylinder is calculated at least one segment later than the valve control time for the outlet valve of the same cylinder. The segment is determined by the phase angle between the upper dead centers of two pistons of cylinders which follow one another directly in the ignition sequence.

摘要： In order to control electromechanically activated charge cycle valves, a circuit is provided in which placement control elements actuate an output stage for the electromechanically activated charge cycle valves and control a gentle placement of the charge cycle valves in a respective end position. For the purpose of communication with the operational control unit of the internal combustion engine, a digital communications computer is provided which provides the placement control element with timing signals. As a result, the placement control elements are freed of communications functions and can be dedicated to performing the placement control in real time.

摘要： A method for the closed-loop control of a nonlinear controlled system in which a state variable of the controlled system is determined and an actuating value is determined using a control method and a reference variable. In addition, by using the state variable of the controlled system, a correction value is read from a linearization characteristic curve and multiplied by the actuating value and the product is specified as new desired value for the controlled system. The linearization characteristic curve is chosen in such a way that multiplication of the linearization characteristic curve by the nonlinear control action of the controlled system yields a linear control action.

摘要： A method of starting an internal combustion engine having an injection system and characteristic variables includes the steps of supplying an injection system with an operating parameter that is determined from characteristic variables, supplying a speed regulator with an initialization value as an initial starting variable, and regulating a speed of an internal combustion engine up to an idling speed with the speed regulator based upon the initialization value. The acceleration to idling speed is carried out with the aid of the speed regulator based on the initialization value. The injection system is supplied with a mass of fuel to be injected. Regulation is carried out with a speed regulator already present in an engine controller. The initialization value is stored in a characteristic curve as a function of coolant temperature. The initialization value is applied to a first injection operation of the internal combustion engine.

摘要： A method for regulating the smooth running of a multicylinder internal combustion engine. An inverse linear path model estimates a characteristic process variable from state variables of the internal combustion engine, that is to say actual values, in particular engine speed, fuel quantity, operating temperature, charging pressure, etc. A desired value is compared with the actual value that is determined from state variables of the internal combustion engine by a measuring element. The actual value shows the rotational acceleration contribution of each cylinder. The difference between the actual value and the desired value is supplied to a controller that corrects the combustion in the individual cylinders in such a way that the actual value approaches the desired value. This ensures that the regulation for the smooth running of the engine takes effect both for stationary and non-stationary operating phases of the internal combustion engine.
