摘要： A method and an arrangement for operating and monitoring an internal combustion engine are suggested wherein, in at least one operating state, operation is undertaken with a lean air/fuel ratio. At least one quantity, which represents the degree of actuation of the accelerator pedal, and a quantity, which represents the engine rpm, are detected and, in at least one operating state, only an operation of the engine with an approximately stoichiometric or rich mixture is permitted and/or only an operation with limited air supply is permitted. The operation is monitored on the basis of at least one operating variable of the engine.

摘要： A method and a device for controlling a drive unit of a vehicle in which the actual torque of the drive unit is compared to a specified, maximum allowable torque for monitoring purposes. When the actual torque exceeds the maximum allowable torque, the drive unit is controlled in a torque-reducing manner. The actual torque of the drive unit is determined on the basis of a signal representing vehicle acceleration. Instead of comparing absolute values, a differential comparison is carried out.

摘要： A method and an arrangement for operating internal combustion engines is suggested which is operated in at least one operating state with a lean air/fuel mixture. The fuel mass, which is to be injected, or the injection time, which is to be outputted, is determined in dependence upon a desired value. For monitoring the operability, the actual torque of the engine is determined on the basis of the fuel mass, which is to be injected, or the injection time, which is to be outputted, or the outputted injection time and compared to a maximum permissible torque and a fault reaction is initiated when the actual torque exceeds the maximum permissible torque. Parallel to the above, a quantity, which represents the oxygen concentration in the exhaust gas, is compared to at least one pregiven limit value and a fault reaction is initiated when this quantity exceeds the limit value.

摘要： A method and a device for controlling an engine, in which a control module calculates a setpoint torque based on an accelerator position and calculates an air mass and a fuel mass from this setpoint torque. In the process, a setpoint value for lambda (ratio of air mass to fuel mass) is taken into account when the fuel mass is calculated. A monitoring module calculates a monitoring value for the air mass from the fuel mass and compares it to a measured air mass for fault detection.

摘要： In an internal combustion engine, a real fuel quantity (rk_w), supplied from a high-pressure region of a fuel system into a combustion chamber of the engine, depends on a real rotational moment. In addition, the control duration (dwmsvo) of a volume control valve, with which the fuel supplied from a fuel pump into the high-pressure region can be affected, depends on the difference between a real pressure and a determined pressure (prist) in the high-pressure region. The supply output of the fuel pump, which supplies into the high-pressure region, depends in turn on the rotational speed (nmot) of a crankshaft of the engine. In order to avoid problems relating to too much or too little fuel being injected into the combustion chamber of the engine, it is proposed that a real control duration (dwmsvo) of the volume control valve, the determined rotational speed (nmot) of the crankshaft of the engine, and the determined pressure (prist) in the high-pressure region determine a test fuel quantity (rk_um) and that this test fuel quantity is compared with a real fuel quantity (rk_w_determined from the real rotational moment.

摘要： The invention is directed to a method for determining the actual torque (M_act) developed by an internal combustion engine by evaluating the trace of the rpm (n) of the crankshaft of the engine. The method is simple, operates rapidly and requires especially little computation power. An index (A) for the actual torque (M_act) can be determined from the rpm (n) in different ways. The actual torque (M_act), which is developed by the engine, is determined from the index (A). The index (A) can be determined in a work stroke of a cylinder of the engine from: (a) the difference of the areas (F1, F2) between the trace of the rpm (n) and the mean rpm (n_) or from the ratio of the areas (F1, F2); (b) the difference or the ratio of the extremes (E1, E2) of the maximum or minimum rpms (n) to each other; and (c) the difference or the ratio of the extremes (E1, E2) and the mean rpm (n_).

摘要： In a method for diagnosing an internal combustion engine having first and second fuel injectors, if a misfire is detected, the following steps are performed in sequence: a first fuel quantity of the fuel is introduced only by the first fuel injector; a check is performed to determine whether a misfire results from the introduction of a first fuel quantity in the first step; a second fuel quantity of the fuel is introduced only by the second fuel injector; a check is performed to determine whether a misfire results from the introduction of the second fuel quantity in the third step; and an engine error is diagnosed if a misfire was detected in the second or in the fourth step.

摘要： In a method and a device for operating an injection device (5) for an internal combustion engine, the injection device (5) includes injection valves (40), via which fuel is injected directly into combustion chambers (100) of the internal combustion engine. Mechanisms are provided for detecting misfirings (310), and for determining a fuel pressure (320).

An electrical fault in an injection device (5) is detected when misfirings of cylinders (110) assigned to an output stage bank of the injection device (5) are observed, and the fuel pressure has dropped below a threshold value (SW).
