Description

ABSTRACT:
A catalytic reactor for the exhaust gases of a motor vehicle comprising a catalyzer bed through which a pipe extends having one end connected to a secondary-air source. The other end of the pipe connected to a chamber wherein a simple and economical temperature detector, such as bimetal, is installed. When the temperature of the catalyzer bed exceeds a predetermined value, as measured by the temperature detector, a valve is electrically activated by an electrical circuit containing said detector, whereby exhaust gas bypasses said catalyzer bed.
