| 摘要： | In Mesa, Arizona, a total of 1 SO vehicles were recruited at a local I/M lane and tested for running loss emissions at the Automotive Testing Labs (ATL). Running loss emissions were measured in a Running loss SHED (RL-SHED) for a 25 minute, 7.5 mile trip on a hot summer day (95°F). Vehicles from model years 1971 through 1991 were tested. The program identified 30 vehicles as candidates for repair and retest. The result showed a very high (9()±%) effectiveness for the repairs. Repeat tests were run on 10 vehicles to provide an estimate of test-to-test variability. |
