Abstract
The catalytic converter has a first catalyst case containing a catalyst for cleaning a fluid, a second catalyst case containing a catalyst for cleaning the fluid downstream of the first catalyst case, a sensor for detecting the fluid is attached, and a connecting portion connected between the first catalyst case and the second catalyst case, the cross-sectional area of the first flow path of the fluid in the connecting portion is smaller than the cross-sectional area of the second flow path of the fluid in the first catalyst case, the first flow path, the mounting position side of the sensor with respect to the second flow path, the displacement width of the opposite side facing the mounting position is provided so as to be larger than the displacement width.
Claims5
A catalytic converter comprising:
- a first catalyst case that houses a catalyst that cleans a fluid;
- a second catalyst case that houses a catalyst that cleans the fluid on a downstream side of the first catalyst case;
- and
- a connecting portion on which a sensor that detects the fluid is mounted, the connecting portion being connected between the first catalyst case and the second catalyst case,
- wherein a sectional area of a first flow path of the fluid in the connecting portion is smaller than a sectional area of a second flow path of the fluid in the first catalyst case, and
- wherein the first flow path is provided such that a displacement width with respect to the second flow path on a mounting position side of the sensor is larger than a displacement width on an opposite side of the first flow path from the mounting position.
