| Abstract: |
A separator for substantially resolving at least one component of a process stream, such as from the exhaust of an internal combustion engine. The separator includes a body defining a chamber therein. A nozzle housing is located proximate the chamber. An exhaust inlet is in communication with the nozzle housing and the chamber. A nozzle assembly is positioned in the nozzle housing and includes a nozzle moveable within and relative to the nozzle housing. The nozzle includes at least one passage formed therethrough such that a process stream entering the exhaust inlet connection passes through the passage formed in the nozzle and imparts a substantially rotational flow to the process stream as it enters the chamber. A positioning member is configured to position the nozzle relative to the nozzle housing in response to changes in process stream pressure thereby adjusting flowrate of said process stream entering into the chamber.

What is claimed is:
1. An exhaust system for managing emissions from an internal combustion engine producing exhaust of varying pressure, the exhaust system comprising:
- an exhaust manifold receiving at least a portion of the exhaust produced by the internal combustion engine;
- an exhaust resonance chamber in communication with said exhaust manifold so as to receive at least a portion of the exhaust produced by the internal combustion engine; and
- a muffler, said muffler including a separator in communication with at least said exhaust resonance chamber so as to receive at least a portion of the exhaust produced by the internal combustion engine, said separator configured for adjusting flowrate of exhaust through the muffler in response to changes in exhaust system pressure, and said at least one separator configured for imparting a substantially rotational motion to exhaust received from the exhaust system so as to facilitate substantial resolution of at least a first component of said exhaust, and wherein said at least first component of said exhaust is substantially in liquid form.
