摘要： During the starting phase of an internal combustion engine with fuel injection so-called pilot injectors (I) are used to establish a film on the cylinder walls and at the same time to provide an ignitable mixture for the first combustion. At this point in time the cam shaft and the crankshaft are not yet synchronized and the position of the pistons is unknown. The method according to the invention allows determination of the sequence of the pilot injectors (I) depending on the possible relative positions during the stop periods of the internal combustion engine, said positions being known beforehand.

摘要： A wall film can form around a temperature sensor as a result of the temperature sensor being fitted in the intake port of the internal combustion engine, in such a manner that at least some of the fuel jet from the injection valve is sprayed onto it. The reduction in temperature that occurs as a result of the enthalpy of vaporization at the temperature sensor is measured and used as a criterion for determining the quality of the fuel supplied to the internal combustion engine. This information can be used to correct the change in injection time exclusively or in addition to adapting the starting quantity and/or using the lack-of-smoothness method.

摘要： A correction factor takes into account the possible change in the quality of the fuel fed to an internal combustion engine between shut-down and restarting of the internal combustion engine. The correction factor is applied to the basic injection time period in the internal combustion engine. The correction factor is weighted with a weighting factor that is selected as a function of the filling level of a fuel reservoir container holding the fuel when the internal combustion engine is shut down, and of the filling level when the internal combustion engine is restarted.
