Summary:

This paper presents a method of balancing the cylinder to cylinder torque fluctuation of an idling engine by controlling the individual spark timing. This method has the capability to compensate for individual fuel/air imbalance that might occur for example due to miscalibration of a fuel injector. The method is based upon noncontacting crankshaft angular speed flucuations and upon a control system that regulates individual spark timing in response to imbalance in that speed variation. The theory of the method is explained and experimental verification of the method is presented for a 4 cylinder engine
