In the reciprocating engine with multi-cylinders, estimation of cylinder imbalance characteristics is an important issue for online balancing control in order to obtain high quality torque generation and reduce emission. This paper addresses the individual cylinder A/F estimation with single sensor and control problem. First, a simple model is proposed that provides an estimation of the individual cylinder A/F with multiple sampling data of the single sensor during a cycle. Then, using the model-based estimation, a feedback control approach is shown that is cycle-based PI regulation with the fuel injection as control input. Finally, experimental results carried out on an engine testbench are demonstrated to validate the estimation and the control effectiveness.
