Abstract
A fuel control system for a vehicle comprises a fuel delivery module, a torque ratio determination module, and a correction factor module. The fuel delivery module supplies first and second amounts of diesel fuel to a cylinder of an engine during first and second combustion cycles for the cylinder, respectively. The second combustion cycle occurs after the first combustion cycle. The torque ratio determination module determines a torque ratio based on torque output by the engine during the first combustion cycle and a torque requested for the first combustion cycle. The correction factor module determines a fuel correction factor based on the torque ratio and adjusts the second amount based on the fuel correction factor.
