Title:
排気センサの遮熱板構造
Document Type and Number:
Japanese Patent JP7368290
Kind Code:
B2
Abstract:
The utility model aims to provide a heat insulation plate structure of an exhaust sensor, which can restrain the influence of radiant heat on the exhaust sensor when a vehicle stops and can cool the exhaust sensor when the vehicle runs. In order to solve the problem, the heat insulation plate structure of the exhaust gas sensor is provided with a heat insulation plate for blocking heat from an exhaust system at a mounting part of the exhaust gas sensor mounted on an exhaust pipe of a vehicle, and the heat insulation plate is provided with a wall part surrounding the exhaust gas sensor in the circumferential direction. The height of the wall portion has a structure such that the upstream side is lower than the downstream side in the flow direction of traveling wind blown to the exhaust sensor when the vehicle is traveling.
