Abstract:
A control system for an internal combustion engine that receives a fuel/air mixture and has:an intake tract; electromechanically activated charge cycle valves each having: an open end position; a half-open position of rest; a closed end position; and two electromagnets selectively moving a charge cycle valve into the open end position and the closed end position and holding the charge cycle valve in a respective position; an ignition system; and an injection system, the control system comprising: a control device for monitoring an operational capability of the charge cycle valves; said control device connected to the ignition system and the injection system and actuating the ignition system and the injection system; said control device programmed to prohibit an injection at the injection system and to prevent undesired ignition of the fuel/air mixture when a charge cycle valve exhibits a faulty function by either one of not closing and not closing completely; said control device having: assemblies each programmed to detect the faulty function of the charge cycle valves; OR elements each having: inputs; and an output connected to at least one of the injection and ignition systems for actuating at least one of the injection and ignition systems; and signal lines connecting each of said assemblies to an input of a respective one of said OR elements.
