Demonstration of the Environmental Data Corporation Spectral Fuel Conservation System. Quarterly report, October-December, 1979

Description: A program plan was prepared and submitted to the Department of Energy in November 1979. The criteria that must be satisfied by the host site for a successful demonstration of the Spectral Fuel Conservation System have been developed and are included in this report. The process of demonstration site selection is underway and is expected to be completed on schedule by March 31, 1980. Preliminary discussions with Union Carbide indicate that the coal-fired boilers at the company's specialty chemica… more

Increasing the Fuel Economy and Safety of New Light-DutyVehicles

Description: One impediment to increasing the fuel economy standards forlight-duty vehicles is the long-standing argument that reducing vehiclemass to improve fuel economy will inherently make vehicles less safe.This technical paper summarizes and examines the research that is citedin support of this argument, and presents more recent research thatchallenges it. We conclude that the research claiming that lightervehicles are inherently less safe than heavier vehicles is flawed, andthat other aspects of vehi… more

Investigation of a rotary valving system with variable valve timing for internal combustion engines: Final technical report

Description: The objective of the program was to provide a functional demonstration of the Hansen Rotary Valving System with Variable Valve timing (HRVS/VVT), capable of throttleless inlet charge control, as an alternative to conventional poppet-valves for use in spark ignited internal combustion engines. The goal of this new technology is to secure benefits in fuel economy, broadened torque band, vibration reduction, and overhaul accessibility. Additionally, use of the variable valve timing capability to v… more

Fuel-cycle energy and emissions impacts of tripled fuel-economy vehicles

Description: This paper presents estimates of the fill fuel-cycle energy and emissions impacts of light-duty vehicles with tripled fuel economy (3X vehicles) as currently being developed by the Partnership for a New Generation of Vehicles (PNGV). Seven engine and fuel combinations were analyzed: reformulated gasoline, methanol, and ethanol in spark-ignition, direct-injection engines; low-sulfur diesel and dimethyl ether in compression-ignition, direct-injection engines; and hydrogen and methanol in fuel-cel… more

Selecting the incremental use of the fuel cycle and regional reference environments

Description: To demonstrate the accounting framework and give some practical meaning to the concept of external costs of various stages of the fuel cycle, we will apply the approach to a limited number of case studies. These case studies will emphasize two of the major sectors for which energy sources are needed: electricity production and transportation. Because the intent here is to illustrate the approach and not to derive sweeping generalizations or comparisons, criteria and proposed selections for the … more

Petroleum Market Model of the National Energy Modeling System. Part 1

Description: The purpose of this report is to define the objectives of the Petroleum Market Model (PMM), describe its basic approach, and provide detail on how it works. This report is intended as a reference document for model analysts, users, and the public. The PMM models petroleum refining activities, the marketing of petroleum products to consumption regions, the production of natural gas liquids in gas processing plants, and domestic methanol production. The PMM projects petroleum product prices and s… more

Gasoline-fueled hybrid vs. conventional vehicle emissions and fuel economy.

Description: This paper addresses the relative fuel economy and emissions behavior, both measured and modeled, of technically comparable, contemporary hybrid and conventional vehicles fueled by gasoline, in terms of different driving cycles. Criteria pollutants (hydrocarbons, carbon monoxide, and nitrogen oxides) are discussed, and the potential emissions benefits of designing hybrids for grid connection are briefly considered. In 1997, Toyota estimated that their grid-independent hybrid vehicle would obtai… more
