Abstract:
1. A method of operating an internal combustion engine configured to utilize fuels having two different reactivities from a single fuel source, the method comprising: storing a first fuel in a first fuel reservoir, the first fuel having a first reactivity; converting a portion of the first fuel to a second fuel having a second reactivity; introducing the first fuel to a variable volume defined by a piston moving in a cylinder at a first time when the piston is relatively closer to a bottom dead center (BDC) position; introducing the second fuel having a second reactivity into the variable volume at a second time when the piston is relatively further from the BDC position; sensing by a sensor operatively associated with internal combustion engine one or more operating parameters, communicating the one or more operating parameters to a controller operatively associated with the internal combustion engine adjusting by the controller the step of converting based on the one or more operating parameters reflective of operation of the internal combustion engine.
