Abstract
A fuel quality sensor is provided for use with an engine system. The fuel quality sensor may have a single sensing element configured to sense a thermodynamic property of an unknown mixture of gaseous fuel, and a heating element configured to increase a temperature of the unknown mixture of gaseous fuel at the single sensing element to multiple different temperature levels. The fuel quality sensor may also include a microprocessor configured to calculate a fuel parameter of the unknown mixture of gaseous fuel as a function of only the thermodynamic property sensed at the multiple different temperature levels.
