EXPERIMENTAL RESULTS AT SNCF OF A DIESEL ENGINE WITH HIGH SUPERCHARGING (HYPERBAR SYSTEM)
EXPERIMENTATION REALISEE PAR LA SNCF AVEC UN MOTEUR DIESEL A TRES HAUTE SURALIMENTATION (HYPERBAR)
In order to increase train speed without overloading the existing infrastructure, the locomotive fleet requires thermal engines with high specific power for its non-electrified lines. The diesel engine, supercharged with the "Hyperbar" process is liable to meet this need, like the gas turbine, but approximately with the energy output of a diesel motor. As an experimental basis, an SNCF shop installed a 590 kW (800 hp) POYAUD 520-V8 type 8 cylinder engine on an RGP railcar in June 1977. This train set is now on commercial service. Encouraging results obtained foresee a new and favorable era for diesel engine in rail traction both for mean-power railcars and line locomotives.
