The effect of swirl on combustion in a pancake chamber spark ignition engine: the case of constant inducted kinetic energy

This experimental investigation is an initial step in separating the influences of swirl and inducted kinetic energy on combustion in a homogeneous charge engine. By rotation of the intake port about the axis of the intake valve, the swirl ratio was varied from zero to 2.8 while maintaining constant intake port flow, and hence constant inducted kinetic energy
