A group of 50 trucks, of model years 1965 to 1973, 6,000 to 16,000 lbs gross vehicle weight were tested for exhaust and evaporative emissions using a modified light duty procedure. The results from these tests, together with other similar tests initiated by the Environmental Protection Agency, will form the baseline emissions data for this test procedure. The group of trucks which was assembled for these tests was sufficiently varied to contribute to a proper baseline. All trucks completed the test procedure successfully, however, it appears that some adjustment in road load power settings may be required at dynamometer inertia settings above 8,500 lbs. (Author)
