1. A fuel control system for an engine, the fuel control system comprising:
a first sensor coupled to the engine, the first sensor configured to generate a signal indicative of a pressure within a cylinder of the engine; a second sensor coupled to the engine, the second sensor configured to generate a signal indicative of an amount of Nitrous Oxide (NOx) present within an exhaust gas of the engine; a fuel reformer coupled to the engine, the fuel reformer adapted to reform a portion of a fuel supplied to the engine into hydrogen (H2) and Carbon Monoxide (CO); an Air Fuel Ratio (AFR) unit coupled to the engine, the AFR unit adapted to control an air fuel ratio of a mixture of air and the fuel supplied to the engine; and a controller coupled to the first sensor, the second sensor, the fuel reformer, and the AFR unit, the controller configured to:
receive the signal indicative of the pressure within the cylinder of the engine;determine a Coefficient of Variation (COV) of Indicated Mean Effective Pressure (IMEP) associated with the engine based on the received signal indicative of the pressure within the cylinder of the engine;receive the signal indicative of the amount of NOx;compare the COV of IMEP and the amount of NOx with a threshold combustion stability and a threshold amount of NOx respectively; andregulate, based on the comparison, at least one of the fuel reformer and the AFR unit to control at least one of the combustion stability and the amount of NOx. |
