摘要
Various methods and systems are provided for individually adjusting fueling to cylinders of an engine based on an output of a knock sensor coupled to each cylinder. In one embodiment, a method for a multi fuel engine comprises individually adjusting, for each cylinder of the engine, one or more of a gas flow rate of gaseous fuel, a diesel flow rate of diesel fuel, an injection or induction timing of gaseous fuel, or an injection timing of diesel fuel based on each of an output of an individual knock sensor for each cylinder, a knock threshold for current engine operating conditions, and a reference value of individual cylinder output.
