Abstract: AbstractDownsizing in combination with turbocharging represents the main technology trend for meeting climate relevant CO 2 emission standards in gasoline engine applications. Extended levels of downsizing involve increasing degrees of pulse charging. Separation of cylinder blow downs, either with double entry turbines or valve train variability, is key for achieving enhanced rated power and low-end-torque targets in highly boosted fourcylinder engines.However, double entry turbines feature specific developme…
