Feedback control of combustion phasing based on a crankshaft integrated torque sensor was developed for a spark ignited five cylinder engine. A cylinder individual measure for combustion phasing, called 50% torque ratio, is extracted from the torque signal and used by a spark advance controller. The estimated torque ratio is based on a simplified estimation algorithm where torsional resonances in the crankshaft are neglected, thus limiting the operating range up to a maximum of about 2000 rpm. The torque ratio measure has been compared with the existing measure 50% burned mass fraction, and proven to be a reliable measure for combustion phasing. The spark advance controller has been evaluated by using internal EGR changes as combustion disturbances and an examination of its cylinder balancing properties was performed.
