Two stroke engine exhaust emissions separator

A separator for facilitating management of an exhaust stream of varying pressure produced by an internal combustion engine, the separator comprising:

• a body defining a chamber;
• an exhaust inlet connection in flow communication with said chamber;
• a nozzle body movably positioned in a nozzle housing, said nozzle body including at least one passage therethrough, the at least one passage being configured to impart a velocity to the exhaust stream so as to facilitate substantial resolution of at least a first component of said exhaust stream;
• and
• a positioning member operatively coupled with said nozzle body and configured to position the nozzle body relative to the nozzle housing to change an amount of exposure of at least a portion of the at least one passage to the exhaust inlet.

A separator for facilitating afterburning of at least a portion of exhaust produced by an internal combustion engine, the separator combining combustion air with the at least a portion of the exhaust so as to facilitate the afterburning thereof, the separator comprising:

• a body defining a chamber;
• a nozzle housing;
• an exhaust inlet connection in communication with said nozzle housing;
• a nozzle assembly substantially disposed in said nozzle housing so that exhaust entering said exhaust inlet connection passes through at least a portion of said nozzle assembly and into said chamber, said nozzle assembly configured to adjust flowrate of exhaust into said chamber in response to changes in exhaust system pressure and to impart a substantially rotational motion to said exhaust passing into said chamber so as to facilitate substantial resolution of at least a first component of said exhaust;
• and
• at least one combustion air inlet in communication with said chamber, combustion air entering said chamber through said at least one combustion air inlet so as to facilitate afterburning in said chamber of at least a portion of said at least a first component of said exhaust.

A separator for facilitating management of an exhaust stream of varying pressure produced by an internal combustion engine, the separator comprising:

• a body defining a chamber;
• an exhaust inlet connection in flow communication with said chamber;
• means for adjusting flowrate of exhaust into said chamber in response to changes in exhaust system pressure;
• and
• means for facilitating substantial resolution of at least a first component of said exhaust wherein said separator produces at least a first and second flow of gas, said first flow of gas being relatively colder than said second flow of gas, and at least a portion of said first flow of gas being directed proximate to said separator so as to facilitate maintenance of said at least one liquid substantially in liquid form.

A separator for facilitating management of an exhaust stream of varying pressure produced by an internal combustion engine, the separator comprising:

• a body defining a chamber;
• an exhaust inlet connection in flow communication with said chamber;
• means for adjusting flowrate of exhaust into said chamber in response to changes in exhaust system pressure;
• and
• means for facilitating substantial resolution of at least a first component of said exhaust wherein the separator is configured to return at least a portion of said at least first component to the engine for combustion.

A separator for facilitating management of an exhaust stream of varying pressure produced by an internal combustion engine, the separator comprising:

• a body defining a chamber;
• an exhaust inlet connection in flow communication with said chamber;
• means for adjusting flowrate of exhaust into said chamber in response to changes in exhaust system pressure;
• and
• means for facilitating substantial resolution of at least a first component of said exhaust;
• wherein said means for adjusting flowrate of exhaust into said chamber in response to changes in exhaust system pressure and said means for facilitating substantial resolution of at least a first component of said exhaust collectively comprise a nozzle assembly, said nozzle assembly being substantially disposed in a nozzle housing and comprising:
• a nozzle in flow communication with said exhaust inlet connection and said chamber so that exhaust entering said exhaust inlet connection passes through said nozzle into said chamber, and said nozzle having at least one inlet aperture, said at least one inlet aperture imparting substantially rotational motion to said exhaust entering said chamber so as to facilitate said substantial resolution of said first component of said exhaust;
• and
• at least one resilient member disposed in operative relation between said nozzle and said nozzle housing so as to automatically facilitate relative changes of position between said nozzle and said nozzle housing in response to corresponding changes in exhaust pressure, said relative change in position of said nozzle at least indirectly facilitating said adjustment of said flowrate of said exhaust into said chamber.
