METHOD FOR CONTROLLING AN INTERNAL COMBUSTION ENGINE AND INTERNAL COMBUSTION ENGINE

An internal combustion engine (1) has a fuel tank (18) and a fuel vapor reservoir (25). According to the method during the tank vent period-before opening the tank vent valve (28) a reference value is updated if a condition is met, and otherwise the existing reference value is maintained,-before ope...

Zusammenfassung:	An internal combustion engine (1) has a fuel tank (18) and a fuel vapor reservoir (25). According to the method during the tank vent period-before opening the tank vent valve (28) a reference value is updated if a condition is met, and otherwise the existing reference value is maintained,-before opening the tank vent valve (28) an opening period is determined as a function of at least one variable,-the tank vent valve (28) is controlled such that the flow achieves the target flow value by the end of the opening period that was determined,-the load level of the fuel vapor reservoir (25) is computed based on the reference value,-a fuel amount is computed based on the load level,-and the fuel amount to be metered by the injection valve (22) is corrected based on the computer fuel amount.
