Air Injection: Operation: Notes

Inlet air to air pump is drawn in through either engine air cleaner or a separate air pump air cleaner assembly. Pressurized air leaving air pump is transmitted through hoses, check valve(s) and air manifold(s) to individual stainless steel tubes or internal passages in cylinder heads and/or intake and exhaust manifolds to each cylinder exhaust port. Fresh air ignites and burns unburned portion of exhaust gases in exhaust system, thus minimizing exhaust emissions.
