Abstract
At least two separate fuels, having different volatility characteristics, are used to control the combustion phasing in a compression ignition engine. Desirably, the separate fuels are produced by distillation by which a parent fuel is separated into separate fractions having different reactivity. The provision multiple fuels by distillation and the control method embodying the present invention are particularly useful in controlling the combustion phasing of homogenous charge compression ignition combustion processes.
