Claims13
In combination in a motor vehicle:
- an internal combustion engine;
- an exhaust manifold coupled to said internal combustion engine;
- a 3 way catalytic converter;
- said exhaust manifold having a downstream end coupled to said 3 way catalytic converter;
- said exhaust manifold having an outer wall surface;
- and, a catalytic converter surrounding said outer wall surface for deriving heat from said outer wall surface and processing ambient air in a path separate from the exhaust processing path.
In combination:
- a motor vehicle:
- an internal combustion engine in said motor vehicle;
- an exhaust flow path downstream from said internal combustion engine;
- a catalytic converter outside said exhaust flow path;
- and,
- a flared scoop located beneath said motor vehicle for funneling ambient pollutants to said catalytic converter for processing said ambient pollutants in a path outside said exhaust flow path.
In combination in a motor vehicle:
- an internal combustion engine having an exhaust flow path;
- a catalytic converter disposed outside said exhaust flow path for deriving heat provided by said internal combustion engine;
- and,
- an open loop system including said catalytic converter coupled to an inlet for receiving ambient pollutants and processing said ambient pollutants outside said outside exhaust flow path.
An ambient air pollution processing system for a motor vehicle having an exhaust manifold comprising:
- an open loop system having an intake for receiving air during forward motion of the vehicle;
- and
- an electrically heated catalytic converter coupled downstream from said intake for processing the received air outside said exhaust manifold, said electrically heated catalytic converter utilizing surplus electrical power generated by said motor vehicle.
An ambient air processing system for a motor vehicle having an exhaust manifold coupled to exhaust system tailpipe for discharging exhaust gases comprising:
- a catalytic converter coupled to said exhaust system tailpipe;
- said catalytic converter receiving said exhaust gases for heating said catalytic converter;
- and
- said catalytic converter further receiving ambient air and processing said ambient air outside the exhaust path for said exhaust manifold.
A method for processing ambient air in a motor vehicle having an exhaust manifold comprising the steps of:
- utilizing exhaust gases from the tailpipe of a motor vehicle to heat a catalyst;
- and
- said catalyst disposed to receive ambient air for processing the ambient air outside of the exhaust path of said exhaust manifold.
An ambient air pollution processing system for processing ambient air outside the exhaust manifold comprising:
- a tailpipe coupled to an exhaust manifold;
- a three way catalytic converter coupled between said exhaust manifold and said tailpipe for processing exhaust gases in said tailpipe;
- and,
- a further catalytic converter attached to the end of said tailpipe for receiving heat from exhaust gases in said tailpipe to provide heating of the catalytic material while also receiving outside ambient air for processing outside said tailpipe.
An ambient air processing system for a motor vehicle comprising:
- an exhaust system manifold;
- a tailpipe coupled to said exhaust system manifold;
- and,
- said exhaust system manifold having an outer wall surface portion more heat transmissive than the tailpipe region thereby providing heating of catalyst material disposed outside said outer wall surface portion of said exhaust system manifold for deriving heat from said outer wall surface portion more heat transmissive than said tailpipe region for treating ambient air outside said exhaust system manifold.
A system for processing exhaust gases from an internal combustion engine including a catalytic converter disposed downstream of an exhaust manifold for processing engine exhaust gas, said catalytic converter receiving ambient air for processing the engine exhaust gases, the improvement comprising a further catalytic converter deriving heat from the exhaust gases for processing ambient air in a separete path outside an engine exhaust gas flow path.
In combination:
- a high temperature exhaust manifold (172) operating in the 1800 degree F. range;
- said high temperature exhaust manifold (172) having an outer wall;
- a catalytic converter deriving heat from the outer wall of said high temperature exhaust manifold;
- and,
- said catalytic converter having an inlet for receiving and processing ambient pollutants in a path separete from the exhaust flow path.
