: Initiation by the U.S. Army Tank-Automotive Command(TACOM) of the Advanced Integrated Propulsion System (AIPS) prompted the development of referee fuels that would (1) indicate to prospective engine/component developers the anticipated quality of fuels available when AIPS is fielded as part of the next main battle tank, and (2) a means for TACOM to ensure that new engines and components would be able to fully demonstrate a 'multifuel capability.' This study resulted in the development of two referee fuels: Type I, A high-volatility, Low-viscosity fuel; and Type II, A low-volatility, high viscosity fuel, both having low cetane numbers. Future multifuel engine design and development work will use these referee fuels to ensure operation on a broad range of fuels that may become available.
It is the purpose of this paper to report the relative miles of transportation that can be obtained from a barrel of crude oil by using different types of engines and fuels. The options that have been studied are: 1. Use of leaded gasoline in an internal combustion engine. 2. Use of unleaded gasoline. 3. Maximum use of diesel engines. 4. Maximum use of the direct injection stratified charged engine. 5. Maximum use of gas turbine engines. It will be shown that the engine-fuel option chosen will have a large effect on the crude oil imports required which, in turn, will have a substantial impact on the United States domestic economy and balance of payments. /GMRL/
We prove that groups acting geometrically on delta-quasiconvex spaces contain no essential Baumslag-Solitar quotients as subgroups. This implies that they are translation discrete, meaning that the translation numbers of their nontorsion elements are bounded away from zero.
