Title: Test and evaluation of the American Pollution Controlled, Inc, exhaust emission control device

Contractor: Northrop Corporation and Olson Laboratories, Inc.

Contract Number: ARB-1902

Research Program Area: Emissions Monitoring & Control

Topic Areas: Mobile Sources & Fuels


The subject of this report is an examination of the extent to which motor vehicle air pollution can be reduced by the installation of an exhaust emission control device on pre-1966 vehicles.

A potentially suitable "used car" emission control device is produced by American Pollution Controlled, Inc (APC). This report documents the installation of 50 APC devices on 50 uncontrolled cars. It covers the ability of Class A garages to accomplish satisfactory installations, the cost of installation, emission reductions achieved, and drivability impressions with and without the device installed. The convertibility of device manufacture from low- to high volume production is also evaluated.

The work performed in the accomplishment of this study was under contract to the State of California Air Resources Board, Standard Agreement ARB 1902. The report was compiled by Northrop Corporation, Environmental Systems, in conjunction with Olson Laboratories, Inc., at Anaheim, California.
