Abstract
The amount of fuel to be injected in each cylinder of a multi-cylinder spark ignition internal combustion engine may be determined with enhanced precision if the fuel injection durations are determined as a function of the sensed mass air flow in all the cylinders of the engine, instead of considering only the air flow in the same cylinder. This finding has led to the realization of a more efficient approach of controlling a multi-cylinder spark ignition internal combustion engine and a feedforward control system.
