ABSTRACT:
The invention is directed to a method for assuring emergency driving functions with a diesel engine when the fuel temperature sensor fails, the diesel engine having a charging-air blower and a charging-air temperature sensor. The method includes performing a fuel temperature dependent correction of specific operating functions by taking the charging air temperature as a basis such that all functions corresponding to a fuel temperature of T.sub.K =+20.degree. C. are fulfilled at a charging air temperature of T.sub.L .gtoreq.0.degree. C. and all functions corresponding to a fuel temperature of T.sub.K =-10.degree. C. are fulfilled at a charging air temperature of T.sub.L <0.degree. C. The functions include the start control path, starting speed, idle speed, control path correction, and basic quantity control.
