2.6L engines use a pulse air feeder system to promote oxidation of exhaust emissions in the rear catalytic converter. The system consists of a main reed valve and sub-reed valve. The main reed valve is controlled by a diaphragm, which is activated by pressure pulses from the crankcase. The sub-reed valve is activated by pulsation in the exhaust system between the front and rear converters.
