The Oldsmobile Cutlass Diverter Valve is mainly responsible for the protection of exhaust components and reduction of exhaust emissions by determining whether the pressurized flow of the AIR pump enters the manifolds, the catalytic converter or vents harmlessly to atmosphere during sudden throttle lift. This Diverter Valve responds to the manifold vacuum and opens passages to the cylinder heads as the engine warms up. It then diverts flow to the converter when normal temperature is reached, which causes the catalyst to activate more quickly and reduces hydrocarbon and carbon monoxide output. During deceleration, it immediately expels excess air outside so rich pulses cannot ignite inside the pipes, which prevents loud backfires as well as damage. Early Oldsmobile models applied a simple vacuum-diaphragm Diverter Valve, but later computer-era models allowed the ECM to accomplish the same task. The basic Diverter Valve poppet and spring configuration remained familiar in every Cutlass generation. Maintaining a healthy Diverter Valve also protects the AIR pump by cooperating with one-way check valves, which maintains fuel economy. In short, the Diverter Valve keeps emissions legal on any road-going Oldsmobile Cutlass.
