Abstract
A control system is provided for use with an engine. The control system may have a plurality of fuel valves, at least one sensor, a starter motor, and a controller in communication with the plurality of fuel valves, the at least one sensor, and the starter motor. The controller may be configured to set at least a first of the plurality of fuel valves to a first admission setting, to set at least a second of the plurality of fuel valves to a second admission setting different from the first admission setting, and to cause the starter motor to crank the engine. The controller may also be configured to determine, based on the signal, which one of the first and second admission settings results in combustion initiation during cranking, and to responsively set all of the plurality of fuel valves to the one of the first and second admission settings.
