ABSTRACT:
A method of operating an internal combustion engine having a combustion chamber with a piston, comprising of adjusting an operating parameter of the engine so that a mixture of air and fuel in the combustion chamber approaches, but does not achieve, an autoignition temperature, and performing a spark from the spark plug so that said second mixture combusts; adjusting a timing of said spark from the spark plug; and adjusting an operating parameter to increase a correlation between said adjusted spark timing and timing of said combustion.
