Title: Electric-assisted Powertrains and Secondary Aerosols: Towards Understanding the Effects of Electrification on Primary and Secondary Aerosol Emissions from Machinery

Abstract:
In the EPSA (Electric-assisted Powertrains and Secondary Aerosols) research project, the team investigated opportunities to reduce particulate emissions from heavy-duty nonroad engines commonly used in agricultural and construction machinery. The experimental design included high-resolution mapping of engine emissions during steady-state operation using four different fuels. Fossil diesel served as the reference fuel and was compared to three renewable diesel alternatives. Additionally, standard dynamic test cycles were evaluated for each fuel type. The role of electrical assistance was examined by simulating dynamic driving cycles both with and without electrical power support to the diesel engine.

Bio:
Kimmo Korhonen, Ph.D. in aerosol physics, is a postdoctoral researcher at Tampere University, Finland. His expertise spans vehicle emission measurements, including both primary and secondary aerosols. He earned his doctorate in 2021 from the University of Eastern Finland, where his research centered on atmospheric ice nucleation.
