Abstract
The invention presented is a crossover section for a vehicle exhaust system that includes a middle pipe and two outer pipes, each outer pipe in contact with and attached to the middle pipe. Diversion gates extend from the middle pipe into each of the outer pipes to divert a sample of exhaust gas into the middle pipe. A sensor, such as an oxygen sensor, is provided to measure one or more components of the combined exhaust. Also provided is an exhaust system that includes the inventive crossover section and a vehicle that includes one or more of the inventive exhaust systems.
Claims23
An exhaust system for an internal combustion engine comprising:
- a first exhaust pipe having an intake end and an exhaust end;
- a middle exhaust pipe having an intake end and an exhaust end;
- a third exhaust pipe having an intake end and an exhaust end;
- a crossover section wherein said first exhaust pipe and said third exhaust pipe are attached to said middle pipe within said crossover section;
- a receiver defined by said middle pipe within said crossover section;
- a first gate extending angularly from said middle pipe into said first pipe within said crossover section;
- and,
- a second gate extending angularly from said middle pipe into said third pipe within said crossover section;
- wherein each of said first gate and said second gate are positioned upstream from said receiver.
A vehicle having an internal combustion engine comprising:
- an exhaust header attached to said internal combustion engine;
- a first exhaust system including;
- a first exhaust pipe having an intake end and an exhaust end said intake end attached to a first exhaust outlet of said header;
- a middle exhaust pipe having an intake end and an exhaust end said intake end attached to a second exhaust outlet of said header;
- a third exhaust pipe having an intake end and an exhaust end said intake end attached to a third exhaust outlet of said header;
- a crossover section wherein said first exhaust pipe and said third exhaust pipe are fastened to said middle pipe within said crossover section;
- a receiver defined by said middle pipe within said crossover section;
- a first gate extending angularly from said middle pipe into said first pipe within said crossover section;
- and,
- a second gate extending angularly from said middle pipe into said third pipe within said crossover section;
- wherein each of said first gate and said second gate are positioned upstream from said receiver.
A crossover section for an exhaust system comprising:
- a middle pipe having an input end and an output end;
- a first outer pipes having an input end and an output end and in contact with and attached to said middle pipe;
- a second outer pipe having an input end and an output end and in contact with and attached to said middle pipe;
- a first gate extending angularly from said middle pipe into a first outer pipe;
- a second gate extending angularly from said middle pipe into said second outer pipe within said crossover section;
- and,
- a receiver defined by said middle pipe and downstream from said first gate and said second gate.
