Apparatuses, processes, and systems including fuel composition determination

Abstract

A powertrain system includes a fuel sensor system adapted to provide an output indicative of a plurality of characteristics of fuel in a fuel supply system adapted to supply fuel to an engine, the plurality of characteristics including information indicative of a fuel temperature and one or more of a fuel density, a fuel viscosity, and a fuel dielectric. An electronic control system in operative communication with the sensor system and configured to receive the output of the fuel sensor system, process the output to determine at a fuel composition parameter, and utilize the fuel composition parameter in controlling one or more operations of the powertrain system.
