12.1 DESCRIPTION AND OPERATION OF DD15 AXIAL POWER TURBINE
AND RELATED PARTS
The Axial Power Turbine (APT) increases the ef
fi
ciency and the economy of the engine by
converting the thermal energy in the exhaust
fl
ow from the turbocharger into mechanical energy,
delivering the resulting torque to the crankshaft. The rated speed of the turbine wheel of the APT
device is about 50,000 rpm. The turbine wheel generates a torque in this range of about 10 N·m (7
lb·ft), which is increased through various gear ratios up to 260 N·m (192 lb·ft). The exhaust gas
fl
ows to the turbine wheel of the APT and drives the wheel. The rotational movement created is
transmitted to the shaft of the small output gear, and from there, to the large output gear of the
hydrodynamic clutch. The rotational speed is reduced because of the gear ratio between the
output gear and drive gear; this gear ratio also multiplies torque output. The hydrodynamic clutch
impeller is a part of the hydrodynamic clutch housing. The vanes on the impeller generate an
oil
fl
ow in the hydrodynamic clutch which sets the turbine wheel of the hydrodynamic clutch
into rotation and the output gear is driven over a shaft. The generated torque is transferred
through the idler gear number four to the crankshaft gear. It is also possible to ensure, via the
hydrodynamic clutch, that matching rotational speed takes place between the crankshaft and the
axial power turbine-drive.
The APT is connected to the engine oil circuit. The gears and the bearing are lubricated and
cooled by the engine oil. The hydrodynamic clutch is supplied with engine oil by the hollow
bearing shaft. One special aspect is the seal between the shaft and the exhaust turbine housing.
The seal between these two components is formed by using two metal sealing rings which are
pressed into their seat by compressed air. The pressure is regulated either by an air sealed pressure
regulator or from the turbo charger compressor.
