Abstract |
The report covers activities in Part I of Phase II of the title study, which developed sampling plans and instrumental 50 heavy duty trucks in normal operation in New York City for 172 days, and, similarly, 5 transit buses for 15 days. Operational profile data included: engine speed, engine load factors, vehicle speed, engine temperature, and throttle valve closure. These data, obtained from sensors installed and calibrated with vehicle operating on a chassis dynamometer, were recorded in digital form at 0.863 second intervals on magnetic tape cassettes. Recorded data was edited and certain values translated to engineering terms using calibration data obtained at time of instrumentation installation. The report describes the sampling plan, instrumentation equipment, calibration methods, edit procedures, survey vehicle types, and technical problems encountered and their solutions. A set of 14 raw data and 14 calibrated, machine-compatible tapes were generated which are available separately from sponsor. Operational use profile data thus generated was basic input to generation of driving cycles for emission testing programs in subsequent program phases by EPA.
