ABSTRACT:
Apparatuses and methods for delivering fuel to at least two combustion chambers of an engine. A fuel controller receives a first fuel quantity signal indicative of a first desired quantity of fuel to be delivered to each combustion chamber of the engine during a combustion cycle. The fuel controller transmits at least one second fuel quantity signal as a function of the first fuel quantity signal, and transmits at least one third fuel quantity signal as a function of the first fuel quantity signal. The second and third fuel quantity signals are indicative of a respective second and third desired quantities of fuel to be delivered during a combustion cycle. The sum of the fuel quantities corresponding to the second fuel quantity signals transmitted during a combustion cycle are less than the first desired fuel quantity.
