Automotive exhaust hydrocarbon reduction during deceleration by induction system devices
Early in 1955 the Automobile Manufacturers Association created the Induction System Task Group to build, test, and evaluate devices for the reduction of unburned hydrocarbon emission from vehicles by induction system methods. Progress on the work performed to mid-1957 by the group is reported. Los Angeles traffic survey data have indicated that the hydrocarbon emissione during deceleration is considerably less than reported by early investigators and that relatively low speed decelerations predominate in traffic. The wide variety of carburetors and engine installations in use today make it unlikely that any one device is entirely suitable for universal adaptation. The Induction System Task Group found that the principle of the vacuum limiting type of device appears to be the best approach to this requirement.
