MASS EMISSIONS FROM TEN PRE-CONTROLLED GASOLINE TRUCKS, AND COMPARISONS BETWEEN DIFFERENT TRUCKS ON A ROAD COURSE

Exhaust emission and fuel economy tests were performed on ten 1965-1969 pre-emission-controlled gasoline-powered heavy-duty trucks while being operated over the San Antonio Road Route (SARR). Each vehicle was also emission tested using a 9-mode chassis dynamometer test procedure. Comparisons were made on emission data between these two test procedures as well as emission data and fuel-economy data from two other heavy-duty testing projects, also conducted by SwRI: Contract EHS 70-113, Part 1-25 1970-1972 emission-controlled gasoline-powered Heavy-Duty trucks; Contract 68-01-2113-Ten 1970-1973 pre-emission-controlled diesel-powered Heavy-Duty trucks.
