Seawater circuit
Apart from the following changes, the seawater
circuit of the TDI engines is the same as that of
the SDI engines.
Changes
On the TDI 150-5/150-5D, 108 kW and 111 kW
TDI engines, the intercooler is located between
the seawater pump and the main heat
exchanger. In order to increase the air density,
the compressed charge air from the
turbocharger is cooled by the seawater.
The TDI 120-5, 88 kW engines as well as the
TDI 100-5, 74 kW engines are not equipped with
an intercooler.
Large coolant circuit
High temperatures occur at the turbocharger
during engine operation. For this reason, the
"large coolant circuit" cools the turbocharger
instead of the exhaust manifold as on the SDI.
