DIRECT INJECTION COMBUSTION CHAMBER GEOMETRY

摘要

Disclosed is an obstruction for use in a combustion chamber of an internal combustion engine. The obstruction is provided and located within the chamber to generate turbulence and break-up or disrupt the soot rich zone within a directly injected quantity of fuel that is burning. More specifically, disclosed is a ring to disrupt fuel jets directly injected into the combustion chamber that impact on or are influence by the ring. The ring can be suspended from the piston or from the fire deck. Disclosed are obstructions that are posts that help generate turbulence that also are targeted at disrupting the soot rich zone of the burning fuel jets. Disclosed is a method for disrupting the soot rich zone or reducing soot generated within the combustion chamber and increase burn rate by impacting the fuel jets on an obstruction within the chamber.
