Abstract: A system includes an internal combustion engine having an air intake, a fuel inlet, and exhaust outlet. The system further includes a NO x sensor operably coupled to the exhaust outlet and structured to provide an exhaust O 2 value, and a controller structured to functionally execute operations for determining a tank biofuel value. The controller includes an operation conditions module that interprets an intake O 2 value, the exhaust O 2 value, and a biofuel O 2 correlation, an O 2 fuel determination module that determines an O 2 biofuel value in response to the intake O 2 value, the exhaust O 2 value, and the biofuel O 2 correlation, and a fuel composition module that determines a tank biofuel value in response to the O 2 biofuel value. The controller further includes a biofuel reporting module that provides the tank biofuel value.
