Title:
EXHAUST SENSOR
Document Type and Number:
WIPO Patent Application WO/2011/129296
Kind Code:
A1
Abstract:
A decline in engine fuel efficiency is prevented by suppressing the increase in engine back pressure through the installation of an exhaust sensor. The exhaust sensor (10), which measures exhaust gas composition, is equipped with a cylindrical sensor body (11) installed on an outer part of an exhaust pipe (5) of an engine (1), a gas inlet (12) that is formed on one end of the sensor body (11) and a gas outlet (13) that is formed on the other end of the sensor body (11). The gas outlet (12) communicates with the exhaust pipe (5) through an entry pipe (16) and the gas outlet pipe (13) communicates with the exhaust pipe (5) downstream of the communicating part (16a) of the entry pipe (16) through a return pipe (17). Due to the pressure difference between the communicating part (16a) of the entry pipe (16) and the communicating part (17a) of the return pipe (17), exhaust gas, after being captured within the inner part of the sensor body (11) from the gas inlet (12), is expelled from the gas outlet (13).
