EPA Presentation Regarding the Advanced Light-Duty Powertrain and Hybrid Analysis (ALPHA) Tool

This page contains a selection of the presentations that EPA has publicly presented about our work on the Midterm Evaluation (MTE). It highlights EPA's benchmarking and modeling activities relating to light duty greenhouse gas (GHG) emissions.

“Characterizing Factors Influencing SI Engine Transient Fuel Consumption for Vehicle Simulation in ALPHA,” SAE Technical Paper 2017-01-0533, 2017, doi:10.4271/2017-01-0533, Dekraker, P., Stuhldreher, M., Kim, Y. (SwRI).

This paper examines a) typical transient engine operation encountered over the EPA city and highway drive cycles, b) EPA’s vehicle and engine testing to characterize that transient fuel usage, and c) changes made to ALPHA to better model transient engine

“Fleet-Level Modeling of Real World Factors Influencing Greenhouse Gas Emission Simulation in ALPHA,” SAE Technical Paper 2017-01-0899, 2017, doi:10.4271/2017-01-0899, Dekraker, P., Kargul, J., Moskalik, A., Newman, K., Doorlag, M., Barba, D.

This paper presents an overview of the laboratory bench marking that was done to support validation of greenhouse gas emission simulation in ALPHA model.
