ABSTRACT:
Creation of a swirling stratified air-fuel charge in an engine combustion chamber is aided by a curved vane or scoop fixedly mounted on the cylinder end and arranged to divide the vortex gas flow introduced through the intake passage into segregated peripheral and core portions. The scoop may also serve as a fuel vaporizing surface and collector for surface quench products. Various arrangements are disclosed for forming a rich mixture in the central core portion adjacent the spark plug to provide the ignition and combustion advantages of a stratified charge.
