Abstract

A sudden expansion combustion chamber comprising a combustion chamber, an inlet port, a backward-facing step layer provided in the combustion chamber having a predetermined thickness so as define the inlet port, and an after-mixing chamber. The sudden expansion combustion chamber is characterized in that it contains at least a slot provided in the backward-facing step layer so as to increase the recirculating flow rate and turbulence of the incoming air, and thus reduce ignition delay.
