Claim 21:
22. A method of operating a compression ignition engine, the method comprising:
drawing a volume of air into a combustion chamber;
moving a piston from a bottom-dead-center (BDC) position to a top-dead-center (TDC) position in the combustion chamber at a compression ratio of at least about 15:1;
injecting a volume of a fuel into the combustion chamber, the fuel having a cetane number less than about 40 and an octane number of at least 95;
igniting the volume of the fuel in the combustion chamber; and
combusting the volume of the fuel in the combustion chamber,
wherein the combustion chamber is a single vessel in which the igniting and the combusting of the volume of the fuel occur, and
wherein the volume of air has a temperature sufficiently high while being drawn into the combustion chamber, such that a delay between initiation of injection of the volume of the fuel into the combustion chamber and initiation of combustion is less than about 1 ms.
