Air Injection Reactor: Operation: Notes

Inlet air to air pump is drawn through an air cleaner. Pressurized air leaving air pump is transmitted through hoses, check valves and air manifolds to individual stainless steel tubes or internal passages in cylinder heads and/or exhaust manifolds to each cylinder exhaust port. Fresh air ignites and burns the unburned portion of exhaust gases in exhaust system, thus minimizing HC and CO emissions.
