Potential sources of non-petroleum based alcohols for vehicular fleet testing

Description: The quantity of alcohol required to supply all of the US Department of Energy's vehicular fleet test fuel needs during the period fiscal year 1980 through 1982 could reach on the order of 1.5 and 1.6 million gallons per year of 200 proof ethanol and fuel-grade methanol, respectively. During the time frame of fiscal year 1982 through 1987, vehicular fleet testing fuel needs could approach 8 and 10 million gallons per year of ethanol and methanol, respectively. In terms of supply, all of the… more

Investigation of fuel economy potential of six 1976-model vehicles

Description: Experimental work was performed to determine the fuel-economy potential of eighteen 1976 model automobiles representing six different models ranging in weight from 3,000 to 5,000 lb. The fuel-economy potential was determined by adjusting the engines to best fuel economy achievable with acceptable driveability but without constraints on emissions. Comparable data obtained on the vehicles adjusted per manufacturers' specifications provided baseline data from which to quantify fuel-economy differe… more

Feasibility of a driver performance data acquisition system

Description: The National Highway Traffic Safety Administration (NHTSA) envisions many future situations in which the effectiveness and consequences of new intelligent vehicle-highway systems technologies will need to be studied in actual production vehicles. Such studies will enable evaluations in vehicles which are familiar to drivers. These studies would be future enhanced by the availability of an instrumentation package that can be easily installed in these vehicles to enable specific vehicle configura… more

Over-the-road shock and vibration testing of the radioisotope thermoelectric generator transportation system

Description: Radioisotope Thermoelectric Generators (RTG) convert heat generated by radioactive decay into electricity through the use of thermocouples. The RTGs have a long operating life, are reasonably lightweight, and require little or no maintenance, which make them particularly attractive for use in spacecraft. However, because RTGs contain significant quantities of radioactive materials, normally plutonium-238 and its decay products, they must be transported in packages built in accordance with Title… more

On-the-road performance tests of electric test vehicle for correlation with road load simulator

Description: A special purpose dynamometer (Road Load Simulator) is being used at NASA Lewis Research Center to test and evaluate electric vehicle propulsion systems developed under DOE's Electric and Hybrid Vehicle Program. To improve correlation between system tests on the Road Load Simulator and on the road, similar performance tests are being conducted using the same vehicle. The results of track tests on the Lewis electric propulsion system test vehicle are described in this report. The tests include r… more

Remote monitoring of emissions using on-vehicle sensing and vehicle to roadside communications

Description: Recent developments in on-vehicle electronics makes practical remote monitoring of vehicle emissions compliance with CARB and EPA regulations. A system consisting of emission controls malfunction sensors, an on-board computer (OBC), and vehicle-to-roadside communications (VRC) would enable enforcement officials to remotely and automatically detect vehicle out-of-compliance status. Remote sensing could be accomplished at highway speeds as vehicles pass a roadside RF antenna and reader unit which… more

Sunrayce 1995. Technical report

Description: From June 20-29, 1995, more than a thousand college and university students from across North America tested their solar cars and strategies against the environment in Sunrayce 95. The 1,250-mile race, from Indiana to Colorado, is the third in a series of collegiate solar-car races across the United States. The tradition began in 1990 with the GM Sunrayce USA from Florida to Michigan. In 1993, the tradition continued as 34 solar cars raced more than 1,100 miles from Texas to Minnesota in Sunray… more

Electric and hybrid vehicle program: Site operator program. Quarterly progress report, April--June, 1994 (3rd quarter of FY-1994)

Description: The DOE Site Operator Program was initially established to meet the requirements of the Electric and Hybrid Vehicle Research, Development, and Demonstration Act of 1976. The Program has since evolved in response to new legislation and interests. Its mission now includes three major activity categories; advancement of Electric Vehicle (EV) technologies, development of infrastructure elements needed to support significant EV use, and increasing public awareness and acceptance of EVs. The 13 Progr… more

Model refinement using transient response

Description: A method is presented for estimating uncertain or unknown parameters in a mathematical model using measurements of transient response. The method is based on a least squares formulation in which the differences between the model and test-based responses are minimized. An application of the method is presented for a nonlinear structural dynamic system. The method is also applied to a model of the Department of Energy armored tractor trailer. For the subject problem, the transient response was ge… more

An on-road shock and vibration response test series utilizing worst case and statistical analysis techniques

Description: Defining the maximum expected shock and vibration responses for an on-road truck transportation environment is strongly dependent on the amount of response data that can be obtained. One common test scheme consists of measuring response data over a relatively short prescribed road course and then reviewing that data to obtain the maximum response levels. The more mathematically rigorous alternative is to collect an unbiased ensemble of response data during a long road trip. This paper compares … more

Demonstration and evaluation of plastic bag streamlining on highway trucks for drag reduction and energy savings. Final report

Description: Highway tests on a tractor-trailer with and without a rear-door drag reduction device have demonstrated a 13 horse-power savings for an 88'' x 94'' rear door at a vehicle speed of 55 mph. Greater savings would be realized for larger trailer door sizes and higher highway speeds. Implementation of such devices on high-use vehicles would provide a payback period of less than a year for installation of rear-door drag reduction devices.
