Turbocharger with variable turbine
geometry
The turbocharger installed in Volkswagen Marine
boat engines operates with variable guide vanes.
Advantage
• By correspondingly influencing the exhaust
flow, the optimum boost pressure is made
available virtually over the entire engine
speed range. This ensures improved
combustion and lower exhaust emission
values as well as high propelling power over
the entire engine speed range.
