Fuel removal method for an internal combustion engine

Abstract

A fuel removal method is for an internal combustion engine that has a closed- and open-loop control system and a lubricant circuit containing a lubricant. The closed- and open-loop control system has characteristic values for operation of the internal combustion engine. The method includes carrying out a load point shift starting from a first operating point of the internal combustion engine to a second operating point of the internal combustion engine with the aid of the closed- and open-loop control system. The load point shift is carried out when a fuel characteristic value, which characterizes a fuel quantity formed in the lubricant, is greater than or equal to a fuel threshold value. The second operating point having a second scavenging gradient which is greater than a first scavenging gradient of the first operating point.
