Abstract

The future of internal combustion (IC) engines is increasingly shaped by regulatory uncertainty, evolving emissions requirements, and a growing diversity of fuels and powertrain architectures. Rather than pointing to a single dominant solution, these forces are driving a broader set of engine opportunities and tradeoffs. This seminar discusses how uncertainty in emissions regulations and policy timelines has influenced the direction of IC engine development and what this means for engineers working on longlived products. Key considerations in engine development are reviewed, emphasizing systemlevel tradeoffs among efficiency, emissions, cost, durability, and customer use cases. An overview of conventional and emerging engine concepts, alternative fuels, and hybridized powertrain options is presented, highlighting how emissions outcomes depend strongly on operating context and system boundaries. The talk concludes with perspectives on future IC engine development areas and the role engines are likely to play within increasingly hybrid and multifuel powertrain strategies.

Bio

Tim Shipp is a Technical Advisor within the Cummins Research and Technology team. He leads a team of engineers focusing on engine performance and engine controls. Tim has worked at Cummins for 17 years. He led the engine performance development to demonstrate 55% brake thermal efficiency as part of the DOE funded SuperTruck 2 program. Tim previously worked directly with California ARB and U.S. EPA to gain emission certification for Cummins engines. Currently he is working on pathways to enable and encourage the use of low carbon fuels. Tim Holds a B.S. in Mechanical Engineering from University of Kentucky and a B.S. in Physics from Eastern Kentucky University.
