Abstract
A system for estimating methane number of fuel includes a sensor configured to generate a signal indicative of a heat release of fuel combusted with an internal combustion engine and a controller. The controller is configured to receive the signal from the sensor, determine a methane number of fuel supplied to the internal combustion engine based on the signal from the sensor, and output a notification based on the methane number.
