    摘要： The invention deals with a method for the operation of an internal combustion engine with at least two cylinders, which can be operated with a fuel of variable quality stored in a tank and/or with fuel blends stored in the tank from a first and at least a second fuel in variable mixing ratios, and wherein variable fuel qualities and/or fuel blends of different compositions require variable air/fuel ratios for the achievement of a stable combustion and/or have a variable vaporization behavior. Provision is, thereby, made for a variation, which is individually adjusted to each cylinder, of the quantity of fuel delivered to the cylinder to be implemented to supply a lean and/or to a rich air/fuel mixture at least one cylinder, for the effect of the variation on the starting characteristics and/or the running smoothness of the cylinder and/or the internal combustion engine to be evaluated and when an improvement in the starting characteristics and/or the running smoothness is achieved, for a fuel adaptation to be implemented for all cylinders.The method makes the quick detection and the avoidance of starting problems possible, when a change in the fuel quality or in the fuel composition occurs with an effect on the ignitability of the fuel.
