Injector Dynamics Assumptions and Their Impact on Predicting Cavitation and Performance

Frank Husmeier, Ph.D., Cavitation Investigation Leader, Cummins Fuel Systems Internal fluid dynamics of diesel engine fuel injectors can have a major impact on engine performance by affecting spray patterns, which in turn influence combustion performance and emissions. These flow patterns also affect fuel injector losses; reducing these losses improves fuel economy and engine performance. Join us for this one-hour webcast and learn how Cummins, using computational fluid dynamics (CFD) to simulate internal fluid dynamics of fuel injectors, has made significant improvements to engine performance.
