Abstract
Improving fuel economy and reducing tailpipe emissions are persistent challenges for the diesel engine industry. Dynamic Skip Fire (DSF®) for diesel engines (dDSF) has the potential to reduce both fuel consumption and tailpipe emissions simultaneously. An analytical model was created by Tula and FEV using FEV’s Complete Powertrain Simulation Platform to conduct a dedicated simulation to study the benefits of dDSF over various characteristic test cycles. In addition, together Cummins and Tula have been collaborating to evaluate dDSF in a heavy-duty application for both real world driving and performance assessments. Results demonstrate that dDSF can achieve significant fuel economy benefit, while realizing marked reduction in tailpipe NOx emissions.
