Date Apr. 21, 1988.A method of eliminating an interfering a.c. component of a fuel injection control signal of an electronically controlled internal combustion engine, in which an injeciton duration control signal tL is computed and generated in an electronic control unit in dependency on various engine variables, such as engine speed, engine load, etc. The control signal tL which may contain an interfering a.c. component is filtered in a filter whose damping effect is variable as a function of predetermined values of at least one engine variable. |
