Description:
A minicomputer controlled automotive emissions sampling and analysis system (the Real-Time System) was developed to determine vehicular modal emissions over various test cycles. This data acquisition system can sample real-time emissions at a rate of 10 samples/s. A buffer utilization program enables incoming digital data from an entire test sequence to be logged rapidly and stored on disc, this permitting the user to reaccess the data at later dates for processing in accordance with modal schemes.
