Special Issue on Emission and Energy Efficiency of Vehicles with Different Power Systems

In recent years, electrified vehicles (battery or fuel cell) have attracted significant attention around the world. These vehicles do not emit pollutants during operation, but the processes to generate electricity or hydrogen often do. Recent internal combustion engines (ICE) equipped with aftertreatment systems can meet rather stringent emission limits (i.e., Euro-VI and China-VI). In certain conditions, the engine system-out CO, HC, and PN (particle number) emissions can be lower than the ambient environment. This is known as “negative emission” from the ICE. The emissions from hybrid vehicles vary with system structure, control strategy, and driving cycles. Hybrid vehicles generally suffer from high emissions during cold-start or low-load conditions, where the catalyst temperature is relatively low. It is essential to evaluate life-cycle vehicle emissions including CO2, NOX, CO, HC, and PN, and compare the energy efficiencies of various power systems, which might be characterized by CO2 emission in certain applications.  
This special issue will focus on new developments and research in vehicles with different power systems, focusing on emission measurement methods, life-cycle emission comparison, system modeling, and technology enablers in emission control and energy improvement, among other topics. It is a peer-reviewed platform for both industry and academia to present new research and developments. Potential topics include, but are not limited to:

  • Development and testing of new emission measurement technologies
  • Consistent ways to evaluate hybrid vehicle emission
  • Novel control strategies of hybrid vehicles
  • Case studies or comparisons of life-cycle vehicle emissions (with different power systems)
  • Modeling and analysis of vehicle level emission and efficiency
  • Advances in power systems in boosting energy efficiency
  • Advances in emission-control technologies
