    摘要: The invention is directed to a method and an arrangement for determining a fuel wall film mass in an internal combustion engine (1) having intake manifold injection. The method and arrangement provide a precise as possible transition compensation also for the case wherein the fuel injection into the open inlet valve (5) of a cylinder (20) takes place. The fuel wall film mass is determined starting from a fuel injection which takes place completely in advance of opening of the inlet valve (5) of the cylinder (20) of the internal combustion engine (1) into the intake manifold (10). The value so determined for the fuel wall film mass is corrected in dependence upon the ratio between the fuel mass, which is injected via the open inlet valve (5) into the combustion chamber (15) of the cylinder (20), and the total injected fuel mass.

    摘要: A device for load detection with altitude adaptation is described, wherein the load is determined based on an altitude-dependent main load signal and a collateral load signal not dependent on the altitude. In connection with defined driving conditions it is possible to detect an altitude deviation by comparison of the main load signal with the collateral load signal. The result of the comparison is integrated in an integrator with a variable time constant to form an adaptation factor, by means of which the collateral load signal is then corrected. The time constant of the integrator is changed in such a way that an altitude adaptation takes place as a function of the maximally possible altitude error.

    摘要: A method and a device for operating an internal combustion engine make it possible to shift the combustion limit. In this context, a predefined output variable of the internal combustion engine such as the torque, for example, is realized in at least one operating state of the internal combustion engine by at least a retardation of an ignition angle. It is checked whether, due to the retardation of the ignition angle, a variable like, for example, a misfiring, characteristic for the combustibility of the air/fuel mixture in a combustion chamber of the internal combustion engine, exceeds a predefined limiting value in terms of a deterioration of the combustibility, and in this case, at least one actuator of the internal combustion engine, different from an actuator for setting the ignition angle, such as the exhaust-gas recirculation valve or EGR valve, for instance, is controlled along the lines of improving the combustibility of the air/fuel mixture.

    摘要: A method and a device for operating an internal combustion engine having multiple cylinders allows for an operating state of the internal combustion engine to be switched over as quickly as possible following the receipt of a switchover request. For this purpose, at least one intake or exhaust valve of a cylinder is switched off or at least one switched-off intake or exhaust valve of the cylinder is switched on again in at least one operating state of the internal combustion engine in response to the switchover request. With the receipt of a switchover request, a delay time or a delay crank angle is ascertained which is required for switching off or switching on again the intake or exhaust valve of one of the cylinders. Starting from the time or crank angle of the receipt of the switchover request and taking into account the ascertained delay time or the ascertained delay crank angle, the cylinder is selected whose at least one exhaust valve following the expiration of the delay time or of the delay crank angle starting from the time or crank angle of the receipt of the switchover request is the next to open in the switched-on state or would be the next to open, though it is switched off. This cylinder is ascertained as the one whose at least one intake or exhaust valve is designated to be the first to be switched off or switched on again following the receipt of the switchover request.
