Method and electronic control unit for controlling the regeneration of a fuel vapor accumulator in internal combustion engines |
摘要 |
Method for controlling a tank venting valve between an internal combustion engine and a fuel vapor storage unit, with the stored fuel vapor being supplied from the fuel vapor storage unit to the internal combustion engine when the tank venting valve is open. A distinction is made between active and inactive tank venting phases, and the purge rate is preset during active tank venting by a purge rate setting means as a function of operating parameters of the engine and/or the tank venting system. If the duration of the inactive tank venting phase exceeds a minimum duration, the purge rate in the subsequent active tank venting phase is temporarily limited to a value below the rate preset by the purge rate setting means.
