Abstract
This document reports the exhaust emissions found in two-hundred fifty 1971 model-year vehicles. The tests were conducted in Detroit, Michigan during March and April 1971 to acquire emission data required to implement provisions of legislation. Measurements were made of carbon monoxide, unburned hydrocarbons, and oxides of nitrogen. A cross-section of projected production of 1971 vehicles by the 1972 Federal test procedures were tested to establish a NOx emission baseline. Measurement of NOx was accomplished utilizing the Chemiluminescence method. The program was conducted in four phases: (1) construction and correlation of a Chemiluminescence instrument; (2) procurement of a representative sample of 1971 vehicles; (3) testing the vehicles; (4) data reduction.
