Host: Chris Bitsis

SwRI is pleased to present a webinar covering three SAE technical papers on Cylinder Deactivation (CDA) in heavy duty diesel engines. Andrew Matheaus presents engine data with and without CDA taken over various light load transient cycles. Andrew Morris discusses the impact of CDA on turbocharger machinery. Gary Neely presents thermal management and hardware improvements to meet ultra-low NOX goals, including CDA.
