ABSTRACT:
A secondary air supply system for a supercharged engine includes a control valve which controls a diaphragm-operated valve. The control valve with solenoid is electrically controlled according to various engine operating conditions. The diaphragm-operated valve tightly closes the secondary air supply passage to prevent exhaust gas from flowing into the intake passage through the secondary air supply passage under a high engine load and high engine speed condition. The diaphragm-operated valve opens the secondary air supply passage to allow air to be supplied into the exhaust gas under a low engine load and low engine speed condition.
