      <title>METHANOL-GASOLINE FUELS FOR AUTOMOTIVE TRANSPORTATION - A REVIEW</title>
      <link>https://trid.trb.org/View/155642</link>
      <description><![CDATA[Recent concern for environmental problems and an eventual shortage of conventional petroleum-based fuels coupled with the potential of obtaining methyl alcohol (methanol) as a product of coal gasification has brought about an interest in the use of methanol as a fuel. In order to assess the feasibility of using methanol as a motor vehicle fuel, either alone (neat) or as a blend in gasoline-type base stocks, its performance, emission and practical use characteristics must be ascertained. To this end this report, which summarizes and evaluates past and current studies concerned with determining these characteristics, is offered. In addition, those performance, emission and practical use consideration characteristics deemed important and found to be lacking in the current technology are identified.]]></description>

      <description><![CDATA[This report describes the laboratory effort to characterize regulated and unregulated exhaust emissions from three-way catalyst-equipped gasoline automobiles operating under malfunction conditions. Three automobiles were evaluated over three driving schedules in the unmodified configuration and in four engine and/or emission control system malfunction configurations. Exhaust emission constituents measured, in addition to the currently regulated emissions, include: particulate, sulfates, aldehydes, sulfides, amines, metals, and several additional elements and compounds. Additional evaluations, in each of the configurations, involved the measurement of regulated emissions over four short-cycle procedures.]]></description>

      <title>AUGMENTATION OF RESEARCH AND ANALYSIS CAPABILITIES FOR TIMELY SUPPORT OF AUTOMOTIVE FUEL ECONOMY ACTIVITIES. VOLUME I - SUMMARY</title>
      <link>https://trid.trb.org/View/170495</link>
      <description><![CDATA[A series of research tasks were undertaken to assess the potential fuel economy improvements for passenger cars and light trucks during the 1980 to 1985 time frame, and later to 1990. Supported by NHTSA's fuel economy activity, this program provided analytical capabilities in the areas of automotive technology, product planning, manufacturing costs and transportation energy economics. Specific subject areas of investigation include: spark ignition engine improvements; fuel economy potential of alternate engines; reductions in tire rolling resistance, aerodynamic drag, and engine friction (through improved lubricants); weight reduction of domestic and certain import passenger vehicles, including a teardown of a Chrysler - Dodge Omni for an analysis of materials and weight and a technology assessment of carbon composites as a future substitute material; manufacturing and consumer costs for the fuel economy improvement areas identified; identification of unregulated diesel emission problem areas in need of research; and a determination of the cost benefits of petroleum conservation by means other than fuel economy standards. Volume I summarizes the results of all tasks, identifies the methodology employed fuel economy benefits expected.]]></description>
