摘要： Proposed is a method for closed loop rail pressure control of a V-type internal combustion engine with an asymmetrical firing order, wherein an actual rail pressure is computed from the measured rail pressure; a system deviation is determined by means of the actual rail pressure and a set rail pressure; and wherein a correcting variable for actuating a pressure actuating element, in particular a suction throttle, for regulating the rail pressure is computed. The invention is characterized by the fact that the actual rail pressure is computed from the measured rail pressure by means of an averaging filter in that below a limit speed (nLi) the rail pressure is averaged over a constant time and in that above the limit speed (nLi) the rail pressure is averaged over a working cycle of the internal combustion engine.

摘要： A method for open-loop and closed-loop control of an internal combustion engine (1) in which the rail pressure (pCR) is controlled via a low pressure-side suction throttle (4), as the first pressure-adjusting element in a rail pressure control loop. A rail pressure disturbance variable (VDRV) is generated to influence the rail pressure (pCR) via a high-pressure side pressure control valve (12), as the second pressure-adjusting element, by which fuel is redirected from the rail (6) into the fuel tank (2). The position of the high-pressure side pressure control valve (12) is determined by a PWM signal (PWMDV), which, when normal mode is set, is calculated as a function of the resulting target volume flow and, when protective mode is set, is temporarily set to a maximum value.

摘要： The invention relates to a method for the open-loop control and the closed-loop control of an internal combustion engine (1), the rail pressure (pCR) being controlled in the normal operating state in a closed loop control mode via an intake throttle (4) on the lower pressure side as the first pressure control member in a rail pressure control loop and at the same time a rail pressure disturbance variable being applied to the rail pressure (pCR) via a pressure control valve (12) on the high pressure side as the second pressure control member.

摘要： In a method for the pressure regulation in a common rail fuel injection system of an internal combustion engine wherein pressurized fuel is supplied to the various combustion chambers of the engine via injectors under the control of an electronic control unit, a first actual control pressure is determined from a measured rail pressure and compared with a desired rail pressure in order to form a first control deviation, whereupon a volume flow depending on the first control deviation is determined and, from the measured rail pressure, a second actual rail pressure is determined using overridingly the second actual rail pressure for the calculation of the controller parts of the high pressure controller.

摘要： A method for automatically controlling an internal combustion engine, where, during normal operation in a first controller mode, a charge air temperature controller is set as dominant for a map-controlled thermostatic valve for automatically controlling the charge air temperature (TLL), or, during normal operation in a second controller mode, a coolant temperature limit controller is set as dominant for the map-controlled thermostatic valve for automatically controlling the coolant temperature (TKM). If a charge air temperature sensor fails, the second controller mode is set with the coolant temperature limit controller dominant, and if a coolant temperature sensor fails, the first controller mode is set with the charge air temperature controller dominant.

摘要： A method for automatically controlling the charge air temperature of an internal combustion engine, in which a coolant flow upstream of a recooler is distributed as a function of the position of a characteristic diagram-type thermostat valve between a recooler coolant flow and a bypass coolant flow. The temperature of the charge air cooler coolant flow is determined downstream of the recooler by the reunited coolant flows, i.e., the recooler coolant flow and the bypass coolant flow. The charge air temperature is determined by the temperature of the charge air cooler coolant flow. A control deviation of a nominal charge air temperature from an actual charge air temperature is computed, a nominal bypass coolant flow is computed as a correcting variable from the control deviation by means of a charge air temperature controller, a control signal (PWM) for actuating the characteristic diagram-type thermostat valve is determined from the nominal bypass coolant flow by a computing unit, and the position of the characteristic diagram-type thermostat valve (6) is determined by the control signal (PWM).
