Abstract
A method for carrying out a hot start in an internal combustion engine has a hot start condition that is recognized on the basis of the coolant temperature and the intake air temperature. A hot start identifier is stored when the coolant temperature and the intake air temperature have both reached a predetermined limit value at least once during a post-operation time after the internal combustion engine is turned off. At the next start of the internal combustion engine, the hot start is then carried out when the hot start identifier is stored and the coolant temperature still lies above its limit value. The method is thus based on temperature sensors that are already present in the motor control system. Therefore, no additional temperature sensors, for measuring the temperature of the fuel, are required.
