    摘要： A method and a device for operating an internal combustion engine to perform a lambda regulation without using a lambda sensor. Fuel is injected for combustion in a combustion chamber of the internal combustion engine. A first quantity of the internal combustion engine is ascertained, which allows a conclusion to be drawn about the behavior of an output quantity of the internal combustion engine, in particular of a torque. The method includes the following: a) a first fuel quantity to be injected is predefined; b) a first value of the first quantity is ascertained, which results from a fuel injection according to the first fuel quantity to be injected; c) the fuel quantity to be injected is modified from the first fuel quantity to be injected in relation to an air quantity to be supplied to the internal combustion engine (1); d) a second value of the first quantity, which results from the change in the fuel quantity to be injected, is ascertained; e) the first value of the first quantity is compared to the second value of the first quantity, and f) as a function of the comparison result, a value for an air/fuel mixture ratio for the first fuel quantity to be injected prevailing prior to the change in the fuel quantity to be injected is ascertained independently of a measured value of a sensor measuring the oxygen level in the exhaust gas.

    摘要： A fuel system for an internal combustion engine includes at least one first fuel pump and a pressure region into which the fuel pump pumps and which communicates with an elastic volume reservoir. The elastic volume reservoir has a characteristic pressure/volume curve, which is defined by at least two points. It is proposed that a first point is defined by a first volume at a first pressure that is somewhat greater than a vapor pressure of the fuel at ambient temperature, and that a second point is defined by a second volume and a second pressure in the pressure region that corresponds to a maximum pressure; the difference between the first and second volumes corresponds at least approximately and at least to a value by which the volume of the fuel in the pressure region decreases upon cooling down from a maximum temperature to ambient temperature.

    摘要： A method for operating an internal combustion engine having a fuel pump with a drive shaft is provided, the fuel pump conveying fuel into at least one fuel-collection line, the fuel being subsequently conveyed to at least one combustion chamber via at least one fuel-injection device. In the method, a quantity of the fuel conveyed by the fuel pump into the fuel-collection line is set by means of a valve device. The valve device is configured to selectively connect a discharge side of the fuel pump to a low-pressure region of the fuel pump (during deactivation phase), and selectively disconnect the discharge side from the low-pressure region (during supply phase). In supplying the quantity of fuel, a supply rate, defined as the number of supply phases of the fuel pump per rotation of the drive shaft, is determined as a function of at least one operating parameter of the internal combustion engine.
