Secondary air supply system for internal combustion engines
Patent
·
OSTI ID:5151256
A control valve is mounted on an air relief line branched off from a secondary air supply line extending from an air pump to an exhaust pipe for controlling the pressure of air in the secondary air supply line. The control valve so controls the pressure of the air in the air supply line as to increase it when acceleration of an engine starts or to decrease it when deceleration of the engine starts, whereby the amount of the secondary air supplied to the exhaust pipe is controlled in response to the acceleration and deceleration of the engine.
