ABSTRACT:
An internal combustion engine is provided with means for creating a vortical stratified charge in a preferably axisymmetric combustion chamber which may be conical in shape. Excessive mixing of rich and lean mixtures, which make up the stratified charge, is avoided by first admitting a homogeneous lean mixture on the intake stroke through a swirl port to develop a vortical motion and subsequently admitting a rich air-fuel mixture toward the end of the intake stroke directed so as to form a swirling pattern of rich mixture around the spark plug. Means are provided for directing and timing the admission of lean and rich mixtures.
