DEVICE FOR INSERTING A SENSOR IN THE EXHAUST CONDUITS OF AN INTERNAL-COMBUSTION ENGINE, AND A CONTROL SYSTEM FOR METERING THE FUEL MIXTURE USING SUCH A DEVICE

摘要

A device for inserting a sensor into the exhaust conduits of an internal combustion engine, wherein the support of the sensor is formed by the sealing element of the assembly gaskets of these exhaust conduits. In accordance with a first variation the sensor is inserted by means of the gasket located between the manifold and the exhaust pipe, and in accordance with a second variation the sensor is inserted by means of the gasket located between the cylinder head and the exhaust manifold. This gasket may comprise several sensors, one per exhaust port. The sensor to be inserted may in particular be of the electrochemical collector type comprising a measuring cell of the concentration-stack type.
