ABSTRACT:
A fuel system and powertrain for a flexible fuel system vehicle utilizes a controller system to control variables in an engine and the final drive optimize operating efficiency of the vehicle while using an alcohol-gasoline blend. The controller system regulates engine operating variables such as fuel pressure, fuel flow, air-fuel flow, air-fuel temperature, and valve timing. The controller system regulates engine operating variables such as transmission gear selection and gear changing as well as differential ratio changes.
