LOW EMISSION VEHICLE ENGINE BASED ON THE AD PROCESS
An existing multifuel system, derived from a diesel engine (AD system KHD) was designed for running on gasoline only. The advantages of the diesel engine (low specific fuel consumption and low gaseous emissions) are combined with those of the Otto engine (high specific power, no soot). The system selected for the transfer to the multicylinder engine is characterized by late mixing of fuel and air near the wall of the piston bowl. It is suitable for supercharging and its fuel consumption is typical for diesel engines. Moreover, the system has low black smoke levels and is largely insensitive to the octane and cetane numbers of the fuel. The relatively high HC and CO emissions of the system were reduced by the installation of a precious metal catalyst. The multicylinder engine BF 6 L 510 adapted with the Deutz-stratified charge system was installed in a Magirus-Deutz R 81 bus with which test bed and roller dynamometer trials were carried out.
