Abstract

PURPOSE: To prevent after-burn from taking place in an exhaust pipe, by detecting the acceleration or deceleration of engine and stopping the supply of secondary air to the exhaust pipe at appropriate time without delay.
CONSTITUTION: When a throttle valve is opened during the acceleration of engine, the boost pressure of an intake manifold 6 falls quickly and the negative pressure of a chamber 1b of an acceleration and deceleration detector A decreases but the decrease in the negative pressure of another chamber 1a is delayed by the resistance of an orifice 4. For this reason, the pressure differs between the chambers 1a, 1b and a diaphragm is pushed leftward and a magnet 8 is moved leftward. As a result, a reed type switch 9 is turned on and a solenoid 10 of an air control valve B is energized. Thereby, a plunger 11 of the valve B is pulled up, a valve part 13 shuts off a passage 15a and the secondary air 21 is all discharged from an outlet port 15b
