摘要

#CMT# #/CMT# The drive device (10) has an injecting device for injecting fuel into combustion chambers of a self-igniting internal combustion engine (12). A fuel mixer (18) mixes petrol and diesel fuels before the supply to the injecting device. A fuel spill-back (30) is provided for the fuel not consumed by the engine, where the fuel spill-back is arranged downstream of the injecting device and/or the engine. A separator is provided in an intermediate tank (32) for separating the petrol from the mixed fuel. A return line (36) is provided for the return of the separated petrol to a petrol tank (14). #CMT# : #/CMT# An independent claim is also included for a method for operating a drive device. #CMT#USE : #/CMT# Drive device. #CMT#ADVANTAGE : #/CMT# The device can be operated from the diesel fuel and also operated from a mixture of the diesel and petrol fuels in an efficient way. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic block diagram of a drive device. 10 : Drive device 12 : Self-igniting internal combustion engine 14 : Petrol tank 18 : Fuel mixer 30 : Fuel spill-back 32 : Intermediate tank 36 : Return line.
