Abstract | A method for controlling delivery of fuel to each cylinder of an engine by adjusting the appropriate fuel valve duration times to each such cylinder based upon either a desired cylinder exhaust port temperature, or a predetermined detonation level. By using the exhaust port temperature measurements and/or detonation level measurements from each individual cylinder as a controlling parameter, the delivery of fuel to that particular cylinder can be trimmed to achieve the desired exhaust port temperature and/or predetermined detonation level. Balancing the exhaust port temperature and/or detonation level for each such cylinder to a common desired exhaust port temperature and/or detonation level likewise produces a substantially identical air/fuel ratio in each such cylinder. Both the exhaust port temperature control loop and the detonation control loop can be initiated at predetermined intervals so as to continuously maintain a balanced air/fuel ratio to each cylinder in any particular engine and, in certain situations, both control loops can operate simultaneously with respect to any particular cylinder. |
