Electronic control device for parameter which influences unsteady running of IC engine

摘要

An electronic control device for a parameter which influences the unsteady running of an IC engine in individual cylinder fashion has a controller for each cylinder to which, on the input side, an individual cylinder unsteady-running signal is passed and which outputs an individual cylinder correction signal that is added onto the named parameter.- DETAILED DESCRIPTION - The individual cylinder correction signals are processed together so that an individual cylinder disturbance is opposed by correction engagements in all cylinders. The displacement of the operating point in the cylinders that are not affected by problems is compensated by a further correction detecting all cylinders globally and working in the contrary sense
