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.
Claims5
A sudden expansion combustion chamber comprising an inlet port, a backward-facing step layer having a predetermined thickness defining said inlet port, and an after-mixing chamber, said sudden expansion combustion chamber being characterized in that it contains at least a slot provided in said backward-facing step layer, which is extending along a lateral direction transversal to a longitudinal axial direction of said combustion chamber, so as to increase recirculating flow rate and turbulence, and thus reduce ignition delay.
A sudden expansion combustion chamber as claimed in claim 6, wherein said slot having a depth less than one third of the thickness of said backward-facing step layer.
