Microprocessor Applications in Vehicle Emissions Testing

The flexibility, high performance, and cost benefits of microprocessors have been effectively applied to the field of automotive emissions testing. This paper describes the use of microprocessors in drivers aid, SHED testing, dynamometer coast down calibration and vehicle storage techniques.

The successful implementation of microcomputers into emissions measurement systems have provided the automotive industry with a cost-effective, powerful and dependable tool for use in meeting the increasingly stringent emissions and fuel economy testing requirements for the 80's and beyond.
