Description of Change: A new turbine nozzle is used in turbine housing on the turbochargers on generator set engines used for prime or continuous power. This change applies ONLY to 50 Hertz, 1500 rpm engines.
The new turbine nozzle will provide higher boost and lower exhaust temperatures. This will result in increased service life from the exhaust valves in applications where the engine is operated at steady high loads.
