Abstract

Exhaust emission tests were conducted on 369 typical 1971-model production light-duty vehicles in consumer use to ascertain the effectiveness of the Federal exhaust emission standards. The vehicles were procured and tested in four different metropolitan areas: Houston, Los Angeles, Detroit, and Denver. The total number of vehicles from each manufacturer (AMC, Chrysler, Ford, GM and Volkswagen) was proportioned approximately to the manufacturer's portion of total production. Each vehicle was tested brand new after receiving dealer preparation (green engine) and again after accumulating 4,000 to 7,000 miles of operation (stabilized engine), using the standard Federal seven-mode, seven-cycle cold start test procedure and the Clayton KEY MODE test procedure.
