Abstract
A combustion control system for a vehicle comprises a position determination module and an ethanol determination module. The position determination module determines a crankshaft angle where a predetermined percentage of a fuel was combusted within a cylinder of an engine during an engine cycle based on one of pressure within the cylinder measured by a cylinder pressure sensor during the engine cycle and torque on a crankshaft measured by a torque sensor during the engine cycle. The ethanol determination module determines an ethanol content of the fuel based on the crankshaft angle.
