A Comparison of Vehicle Refueling and Evaporative Emission Control Methods for Long-Term Hydrocarbon Control Progress
Autor: W. J. Koehl, C. H. Schleyer
Publikováno v: SAE Technical Paper Series.
The U.S. Environmental Protection Agency is studying the merits of four strategies to reduce hydrocarbon emissions from motor vehicles. The four strategies include onboard control of vehicle refueling emissions, Stage II controls on service stations,

Vehicle Onboard Control of Refueling Emissions — System Demonstration on a 1985 Vehicle
Autor: D. W. Lloyd, W. J. Koehl, L. J. Mccabe
Publikováno v: SAE Technical Paper Series.
Two technologies for controlling vehicle refueling emissions have been under consideration by the U.S. Environmental Protection Agency. They are vehicle onboard systems and Stage II service station vapor recovery. A 1978 program showed that onboard s

Fuel Economy Trends in Passenger Car Fleets - Effects of Emissions Controls
Autor: D. S. Gray, J. L. Keller, W. J. Koehl, J. H. Freeman
Publikováno v: SAE Technical Paper Series.
The effects of emissions controls on fuel economy were determined in an American Petroleum Institute study by analyzing fleet fuel consumption data for 20,728 passenger cars (1967-77 models). Data on car weight, engine displacement, compression ratio

METHANOL-GASOLINE BLENDS PERFORMANCE IN LABORATORY TESTS AND IN VEHICLES
Autor: W. J. Koehl, M. A. Roberts, A. W. Crowley, W. L. Wascher, J. P. Kuebrich, W. T. Wotring
Publikováno v: SAE Technical Paper Series.
Performance comparisons between methanol blends and base gasolines were made in vehicle driveability and vapor lock tendency, engine deposits and wear, fuel economy, exhaust emissions, compatibility with fuel system materials, and phase stability of

Impact of Automotive Emissions Regulations on Gasoline Demand
Autor: W. J. Koehl, D. H. Clewell
Publikováno v: SAE Technical Paper Series.
THIS PAPER REVIEWS TRENDS IN CAR DESIGN AND USAGE THAT HAVE AFFECTED GASOLINE CONSUMPTION IN THE PAST AND DISCUSSES SUCH FACTORS AS EMISSION CONTROLS THAT WILL AFFECT FUTURE CONSUMPTION, ESPECIALLY IN LIGHT-DUTY VEHICLES. BETWEEN 1973-1985, DEMAND IS
