摘要:
A compact slip-in spark arrester having an interior shell (125) with a circular cross-section changing in diameter along its axial length which is axially aligned between an inlet cap member (115) and an outlet cap member (145). The tubular center section (130) of the interior shell (125) containing a centrifugal whirling means to remove any particulate matter from the exhaust flow by means of centrifugal force or deflection and trapping the particulate matter in an outer chamber (155) between the interior shell (125) and existing silencer shell (100).
摘要:
A device to trap and remove particulate matter from exhaust of internal combustion engines, without increasing resistance to the flow of engine exhaust is disclosed herein. The system is provided with a single or a plurality of ducts (1 & 2) through which exhaust gases enter tangentially into a hollow chamber (3), causing the gases to spin at high speeds. The spinning gases generate centrifugal force resulting in separation of particulate matter from the exhaust gases. The hollow chamber (3) contains ports (4) and radial projections (5) on its axial surface to allow the separated particulate matter to enter into a trap (6). The particulate matter entering the trap (6) gets stuck to a fine mesh of high temperature resistant porous material that may or may not be electrically charged. The trap (6) is enclosed in a cover (7) that encases the fine mesh which surrounds the ports (4) and radial projections (5). The cover (7) has a single or plurality of ducts (8) connecting the trap (6) to the low pressure area of the rotating gases in the hollow chamber (3) through the port (9) provided at the proximal end of the hollow chamber (3).

A mitigating system to remove contaminants from an exhaust gas and generate electrical power utilizes a first and second particle acquisition tower (PAT) unit, a first and second carbon dioxide precipitator (CAP) unit, a clean air turbine (CAT) unit, and a first and second gravity enhance separator (AGES) unit. The first PAT unit receives and purify the exhaust gas as the first AGES unit is in fluid communication with the first PAT unit. The exhaust gas is then respectively discharge and purified through the first CAP unit, the CAT unit, the second PAT unit as the second AGES unit is in fluid communication with the second PAT unit. Then the exhaust gas is discharged and purified through the second CAP unit and released into atmosphere as clean exhaust gas. Additionally, the exhaust gas is able to produce electricity as the exhaust gas bypasses within the CAT unit.

摘要:
Various methods and systems are provided for separating particles within a gas flow traveling through a gas flow passage of an engine. In one embodiment, a particle separator includes a plurality of vanes positioned across a gas flow passage through which gas flow passes, the plurality of vanes angled with respect to a flow direction of the gas flow, and a particle trap for collecting separated particles, the particle trap disposed in the gas flow passage.
摘要:
A low emissions 2-stroke natural gas fueled engine includes at least one cylinder with an exhaust port in communication with a silencer/catalytic converter unit. The unit has first and second volumes in communication with each other. The first volume dampens spurious exhaust pressure excursions and removes particulates in the exhaust. The second volume houses an oxidation catalyst for treating exhaust to reduce exhaust emissions. The engine oil has at most 10 ppm zinc content to reduce metal poisons contained in the exhaust prior to contact with the oxidation catalyst. The engine oil preferably has a very low ash content to minimize sulfur combustion components in the exhaust to reduce masking of the oxidation catalyst. The first volume preferably has a pressure relief valve set to relieve at a pressure greater than the maximum normal operating pressure of the engine to avoid excessive pressure excursions of the engine exhaust from damaging the oxidation catalyst.
