| Abstract |
The objective of this study was to determine the effectiveness of the Federal diesel smoke regulations in controlling smoke emissions from a group of heavy-duty diesel engines engaged in routine automotive service. A test consisting of 64 trucks and buses, powered by engines certified to meet 1970 smoke standards, was tested for smoke emissions at four-month intervals over a two-year period. Changes in smoke opacity observed during this test period were used to determine, to the extent possible, the effect of time, mileage, and type of service (or duty cycle) on opacity. A secondary project objective was to obtain baseline brake specific emissions data of unburned hydrocarbons, carbon monoxide, and oxides of nitrogen for the vehicles in the test fleet. Smoke opacity tended to increase with time or, equivalently, with mileage. |
