Abstract
A device is proposed for drift compensation in fuel metering systems, in which it is not the metered quantity as such which is controlled in closed-loop fashion, but rather only the position of a quantity-determining member. The object of the invention is to maintain or re-obtain the original association between the fuel quantity and the position signal of the quantity-determining member for the purpose of providing a correct indication of the load state existing at a particular time. The drift compensation is intended to be capable of being performed manually, semi-automatically, or automatically, in an additive and/or multiplicative manner. It can furthermore be realized via a preferably rpm-dependent characteristic curve. The various values may be ascertained, for instance, in connection with running-out and running-up tests.
