METHOD OF ENSURING EMERGENCY TRAVELLING FUNCTION OF DIESEL INTERNAL COMBUSTION ENGINE

摘要

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 TK=+20 DEG C. are fulfilled at a charging air temperature of TL/=0 DEG C. and all functions corresponding to a fuel temperature of TK=-10 DEG C. are fulfilled at a charging air temperature of TL0 DEG C. The functions include the start control path, starting speed, idle speed, control path correction, and basic quantity control.
