The General Motors Air Injection Reactor Air Pump 660108

1966 models of General Motors passenger cars and light trucks sold in California are equipped with the General Motors air injection reactor system. This system meets standards for control of exhaust emissions. Saginaw's contribution to this system is the air pump, which supplies supplementary air for the injection system.
The Sagniaw air pump is a semi-articulated vane type pump of a positive displacement variety. The pump has a design displacement of 10.3 cu in. per revolution with high volumetric efficiency and low horsepower consumption. In the development of the pump, it was necessary to establish durability requirements consistent with the life of the vehicle, providing satisfactory performance without maintenance. It was necessary to perform laboratory tests to insure compliance with these requirements. The Saginaw air pump satisfies all the design objectives and has been accepted for use on 1966 vehicles sold in California.
