Abstract
A method and an arrangement for idle adjustment of an internal combustion engine provide that the idle rpm is increased when the engine is warm. A warm engine is then present when the oil temperature exceeds a threshold at which the oil pressure can become too low. Exceeding the oil temperature threshold is determined in dependence upon the engine temperature, the intake-air temperature and, if necessary, the engine rpm and the load of the engine.
