Abstract
An exhaust filtration system for filtering exhaust gases produced by an internal combustion engine may comprise a fan having an intake side and a discharge side and an air inlet operatively associated with the intake side of the fan. A filter having an inlet surface and an outlet surface is positioned adjacent the fan so that the inlet surface of the filter is positioned adjacent the discharge side of the fan. An influx tube connected to the internal combustion engine is positioned so that its outlet end is located adjacent the intake side of the fan, so that the fan draws in air from the air inlet and exhaust gases from the outlet end of the influx tube and discharges a mixture of air and exhaust gases from the discharge side and into the inlet surface of the filter.
Claims23
An exhaust filtration system for filtering exhaust gases produced by an internal combustion engine, comprising:
- a fan having an intake side and a discharge side;
- an air inlet operatively associated with the intake side of said fan;
- a filter having an inlet surface and an outlet surface, the inlet surface of said filter being positioned adjacent the discharge side of said fan;
- and
- an influx tube having an inlet end and an outlet end, the inlet end of said influx tube being connected to the internal combustion engine so that exhaust gases from the internal combustion engine enter said influx tube, the outlet end of said influx tube being positioned adjacent the intake side of said fan, so that said fan draws in air from said air inlet and exhaust gases from the outlet end of said influx tube and discharges a mixture of air and exhaust gases from the discharge side.
An exhaust filtration system for filtering exhaust gases produced by an internal combustion engine, comprising:
- a fan having an intake side and a discharge side;
- a filter having an inlet surface and an outlet surface, the outlet surface of said filter being positioned adjacent the intake side of said fan;
- an air inlet operatively associated with the inlet surface of said filter;
- and
- an influx tube having an inlet end and an outlet end, the inlet end of said influx tube being connected to the internal combustion engine so that exhaust gases from the internal combustion engine enter said influx tube, the outlet end of said influx tube being positioned adjacent the inlet surface of said filter, so that air from said air inlet and exhaust gases from the outlet end of said influx tube are drawn through said filter and are discharged from the discharge side of said fan.
An exhaust filtration system for filtering exhaust gases produced by an internal combustion engine, comprising:
- fan means for pumping gases from an intake side to a discharge side;
- air inlet means operatively associated with said fan means for allowing air to be drawn into said fan means;
- influx tube means operatively associated with the internal combustion engine and said fan means for allowing exhaust gases from the internal combustion engine to be drawn into said fan means, exhaust gases from said influx tube means mixing with air from said air inlet means to produce diluted exhaust gases before being drawn into said fan means;
- and
- filter means operatively associated with said fan means for filtering diluted exhaust gases.
