Abstract:
According to one or more embodiments, an internal combustion engine may be operated by a method which includes one or more of injecting a first fuel and a second fuel into an engine cylinder to form a fuel mixture, and combusting the fuel mixture with a spark plug to translate a piston housed in the engine cylinder and rotate a crank shaft coupled to the piston. The first fuel may comprise a greater octane rating than the second fuel. A target CA50 may correspond to a minimum in specific fuel consumption of the fuel mixture. The spark plug may initiate combustion at a time such that the internal combustion engine operates with an operational CA50 that is within 20 degrees of the target CA50.

Claim (Index 1):
A method of operating an internal combustion engine, the method comprising:\n passing a first fuel and a second fuel into an engine cylinder to form a fuel mixture, wherein the first fuel comprises a greater octane rating than the second fuel; and combusting the fuel mixture with a spark plug to translate a piston housed in the engine cylinder and rotate a crank shaft coupled to the piston; wherein:\n a CA50 is defined as the angular position of the crank shaft when 50 wt. % of the fuel mixture is combusted, the CA50 measured past a top dead center position of the crank shaft, and the CA50 being a function of the timing of the combustion by the spark plug; \n a target CA50 corresponds to a minimum in specific fuel consumption of the fuel mixture; and \n the spark plug initiates combustion at a time such that the internal combustion engine operates with an operational CA50 that is within 20 degrees of the target CA50.
