Control system for engine

A power system including:

• an engine including:
• a fuel delivery system configured to deliver at least one of a compression ignited fuel and a spark ignited fuel;
• and
• an ignition source configured to ignite one or more of the two fuel types;
• and
• a control system operatively connected to the engine, the control system including:
• a detector configured to sense a signal to change from the compression ignited fuel to the spark ignited fuel;
• a processor configured to receive the signal from the detector and generate an actuation signal;
• and
• at least one actuator configured to receive the actuation signal, vary an operating speed of the engine, and selectively control at least one of the fuel delivery system and the ignition source.

A method of changing a fuel type in an engine, the method including:

• allowing delivery of a compression ignited fuel into the engine;
• igniting the compression ignited fuel in the engine;
• sensing a signal to change a fuel type;
• processing the signal to generate an actuation signal;
• varying an operating speed of the engine based on the actuation signal;
• selectively controlling one or more of a fuel delivery system and an ignition source of the engine based on the actuation signal;
• and
• allowing delivery of a spark ignited fuel into the engine.
