Turbocompound
The turbocompound is a power turbine that is
installed downstream of the turbocharger in the
exhaust stream and which converts the energy of
the exhaust gas into kinetic energy. The kinetic
energy is delivered directly to the crankshaft of the
engine via a 2-gear train with an intermediate
hydrodynamic coupling. This means that up to
35 kW more power can be delivered with simulta-
neous reductions in fuel consumption and
CO
2
emissions.
