At least one physical property of exhaust gas produced by a cylinder of an internal combustion engine may be determined by determining a temperature, TEOC, a pressure, PEOC, and a clearance volume, VEOC, of the cylinder at an end of combustion of an engine cycle, determining a temperature TEVO, a pressure, PEVO, and a clearance volume, VEVO, of the cylinder at an opening of an exhaust valve of the cylinder following the end of combustion of the engine cycle as a function of TEOC, PEOC, and VEOC, determining a value of the at least one physical property of the exhaust gas produced by the cylinder during the engine cycle as a function of TEOC, PEOC, and VEOC, and storing the value of the at least one physical property of the exhaust gas during the engine cycle in memory.
