IN-USE HEAVY DUTY GASOLINE TRUCK EMISSIONS. PART II. SURVEILLANCE STUDY OF CONTROL EQUIPPED HEAVY-DUTY GASOLINE-POWERED VEHICLES

Exhaust emission tests were performed over a period of two and one half years on a fleet of 152, 1970 and 1971 gasoline-powered trucks of over 6000 pounds gross vehicle weight, which were being used in the San Antonio area. During this period, each truck received up to seven periodic tests for HC, CO and NO by means of a chassis-dynamometer version of the nine-mode engine-dynamometer Federal Test Procedure. Ten of these engines received additional tests in order to obtain correlative data between the chassis and engine-dynamometer procedures.
