Claim Text:
1. A method for discharging liquid from an intake tract of a turbocharger arrangement which has an internal combustion engine, which can be supercharged by at least one turbocharger, and a charge-air-cooler which is arranged in the intake tract between the turbocharger and the internal combustion engine, comprising: collecting the liquid in a liquid collector, which has a liquid outlet which can be closed off by a switchable valve, downstream of the charge-air-cooler; performing the subsequent steps only if a temperature (T opening the valve; discharging the liquid from the liquid collector via a discharge line into a crankcase or an oil sump of the internal combustion engine; closing the valve after the predetermined opening duration (Dur); and repeating the above steps of determination, opening, discharging and closing with the predetermined opening frequency (Freq), and wherein the valve is open for the predetermined opening duration (Dur) even after shut-down of the internal combustion engine if the liquid collector is, in relation to gravity, arranged above an inlet point of the discharge line into the crankcase or into the oil sump of the internal combustion engine.
