Fuel Consumption Reduction for Diesel Power Generator Sets through the Application of an Advanced Turbocharger Operating at Constant Speed.

Abstract

The objective of the current research is to demonstrate that a 30KW-400Hz precision gen set, equipped with a VATN (variable area turbine nozzles) turbocharger, can comply with DoD gen set transient specifications. Heretofore poor turbocharger transient response (turbo lag) caused the turbocharged, DED gen set to lose frequency beyond acceptable DoD limits during an instantaneous change in load from 0 to full load. Engine operating conditions were calculated using a computer math model. The turbocharger, with controller, was installed on a four cylinder diesel engine and tested at the engine manufacturer's (White Engine Co.) facility. Fuel consumption data was used to further refine the engine math model. Calculations confirmed at least a 9% fuel savings for the 30KW-400Hz gen set. From the effort of this contract, it can be concluded that a DED precision gen set equipped with a VATN turbocharger can comply with DoD transient requirements.
