Abstract
A system includes a mass determination module and a torque estimation module. The mass determination module determines a fuel mass injected into a cylinder of a homogeneous charge compression ignition (HCCI) engine for a combustion event in the cylinder. The torque estimation module estimates a torque output of the HCCI engine based on the fuel mass.
