ABSTRACT:
An anti-afterburn system for an engine having an air pump, comprising a pressure differential responsive member defining two chambers, a control valve connected to said member, and at least one orifice provided in one of conduits connecting the chambers with an intake manifold of the engine to operate the control valve upon abrupt pressure variation in the intake manifold thereby preventing afterburn. The system further comprises a thermo valve means which is responsive to overheating of the engine or an exhaust system thereof and adapted to supply a pressure to one of the chambers to operate the control valve, thereby interrupting supply of the secondary air from the pump to prevent damages of a thermal reactor and generation of fire.
