    摘要: The invention relates to a method for the open-loop control of an internal combustion engine, which is operated with a fuel blend of an initial and at least one second fuel, the internal combustion engine having a fuel metering system, a tank fill-level gauge for determining the tank content and a change in the tank content, a sensor for the detection of the cylinder charge for determining an air mass supplied to the internal combustion engine and at least one exhaust gas probe for determining and controlling the oxygen content in the exhaust gas in a closed-loop. According to the invention, two methods, which are independent from each other, are used for determining the composition of the fuel blend.

    摘要: The aim of the invention is to optimize the running smoothness of an internal combustion engine. To achieve this aim, the individual cylinders are synchronized with respect to their torque contribution. According to the method, fuel is injected into the combustion chamber of a cylinder in at least one injection step, the at least one injection contributing to the torque of the internal combustion engine. Fuel is injected into the combustion chamber of the cylinder in a torque neutral manner by way of a secondary injection during a working stroke of the cylinder and the amount of fuel of the secondary injection us calculated in such a manner that the exhaust gas substantially corresponds to a stoichiometric air/fuel mixture.
