Patent ID: 7591258

Claim:
A method for controlling a combustion engine including multiple combustion chambers, and multiple, individually-actuated injectors for injecting fuel into the combustion chambers, wherein at least one injector is assigned to each combustion chamber, and wherein the combustion engine further includes a common rail for supplying fuel to multiple injectors, the method comprising: actuating the injectors in accordance with a requested fueling map, the actuation being associated with an unchanged actuation according to the requested fueling map; monitoring an exhaust gas temperature of each combustion chamber; determining an average exhaust gas temperature of the combustion chambers; determining whether the exhaust gas temperature of the combustion chamber deviates by more than a predetermined value from the average exhaust gas temperature; and changing actuation of the injector assigned to the combustion chamber having exhaust gas temperature deviating by more than the predetermined value from the average exhaust gas temperature in order to change an amount of fuel injected, and limiting to a predetermined maximum the number of changes away from the unchanged actuation according to the requested fueling map for each injector.
