ABSTRACT:
Improved combination apparatus is described for creating a fuel rich mixture in a displacer volume, separate from the combustion chamber of a piston internal combustion engine. This mixture is subsequently delivered into the engine combustion chamber, to create a stratified mixture, which is then ignited and burned only in the engine combustion chamber. By use of such stratified mixtures, several benefits over the prior art can be achieved, including: reduced engine friction losses, and consequently improved efficiency; reduced soot formation and engine exhaust emissions; more complete utilization of available air and increased engine power per unit of displacement.
