A method of operating an internal combustion engine having a combustion chamber with a piston, comprising: inducting at least air and fuel vapors from a fuel vapor system; and adjusting an operating condition of the engine so that a mixture of air and fuel in the combustion chamber, including said fuel vapor, approaches, but does not achieve, said autoignition temperature; and performing a spark from the spark plug so that said mixture substantially auto-ignites.
