Characterizing SI Engine Transient Fuel Consumption in ALPHA

Citation:

Characterizing SI Engine Transient Fuel Consumption in ALPHA. SAE - SOCIETY OF AUTOMOTIVE ENGINEERS. SAE International, Warrendale, PA, , 12, (2017).

Impact/Purpose:

To present an approach to capture dynamic fuel consumption during engine transients and then implement these identified characteristics in ALPHA.

Description:

Examine typical transient engine operation encountered over the EPA's vehicle and engine testing drive cycles to characterize that transient fuel usage, and then describe the changes made to ALPHA to better model transient engine operation.
