Abstract: When an internal combustion engine is hot, especially in hot starting or during hot idling, outgassing of fuel occurs upstream of the injection port disk and at the injection ports; as a result, because too little fuel is supplied, the running performance is undesirably impaired. The running performance of the engine is therefore intended to be improved by preventing the development of vapor bubbles. By the provision of a transfer element, in the form of a raised body shoulder formed on the valve seat body, that reduces the heat transfer between the valve seat body and the injection port disk, it is accomplished that the injection port disk cools down as a result of the extracted heat of evaporation of the injected fuel, and thus the danger of vapor bubble development at the injection ports or upstream is reduced. The fuel injection valve is especially suitable for fuel injection systems in mixture-compressing internal combustion engines with externally supplied ignition.

Abstract: In a method and device for driving an electromagnetic load, especially a solenoid valve, which influences the fuel quantity to be injected into an internal combustion engine, the duration of the drive of the solenoid valve can be corrected by a delay time. The delay time can be predetermined as a function of the power supplied to the load.

Abstract: A method is disclosed for adjusting the amount of fuel to be supplied to an internal combustion engine in the case of non-idling operation even when the load signal fails. A plurality of emergency injection times are used which are modified with the manipulated variable of a lambda controller so that an injection time period is associated with each emergency injection time. The injection time periods are arranged such that they cover essentially all the injection times which can occur during the operation of an internal combustion engine. In the method, the lambda control remains switched on and the point at which control is to occur is found by running through the injection time periods. An arrangement for carrying out the method is also disclosed.

Abstract: A venting device for a fuel tank of an internal combustion engine having activated carbon filters via which the fuel tank is vented. During the shut-off phase of the internal combustion engine, the activated carbon filters absorbs the fuel which evaporates in the tank. In the operating phase of the internal combustion engine, the activated carbon filters are regenerated by flushing air. To keep down the flushing air required for regeneration, the activated carbon filter is subdivided into two filter parts, the volume of the first filter part being dimensioned so that, in the shut-off phases of the internal combustion engine, the first filter part reaches a high level of loading. Due to a diffusion-hindering connection between the two filter parts, the second filter part only likewise absorbs fuel vapor after the degree of saturation of the first filter part has been reached.
