Abstract
A system includes an internal combustion engine having an air intake, a fuel inlet, and exhaust outlet. The system further includes a NOsensor operably coupled to the exhaust outlet and structured to provide an exhaust Ovalue, 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 Ovalue, the exhaust Ovalue, and a biofuel Ocorrelation, an Ofuel determination module that determines an Obiofuel value in response to the intake Ovalue, the exhaust Ovalue, and the biofuel Ocorrelation, and a fuel composition module that determines a tank biofuel value in response to the Obiofuel value. The controller further includes a biofuel reporting module that provides the tank biofuel value.
