Abstract
In order to accurately control the operation of the engine while still achieving near optimal swirl rate control, the swirl is controlled by a valve which is separate from the engine throttle valve and which is basically controlled in response to the pressure prevailing across the same. Various operating parameters such as the instant air-fuel ratio of the charge being combusted in the combustion chambers are utilized to modify prerecorded values to those which will induce the best setting for the valve.
