A Study of Exhaust Emissions from 1977-1978 Model Year Motorcycles

摘要

This report presents data obtained as a result of testing and inspection of 150 1977 and 1978 model year motorcycles in the Los Angeles, California area. All vehicles were consumer-owned, street-legal motorcycles. Each vehicle was initially tested in as-received condition by the 1978 Federal Test Procedure. This includes evaporative emissions measurements as well as the exhaust emissions tests. A number of additional tests were performed on some or all vehicles. These included a Two-Speed Idle test, the Highway Fuel Economy test, a model emissions test, the Federal Short Cycle test, the New York/New Jersey test and the Federal Three Mode test.
