This book was released on 1992 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the 1960's and 1970's, engine cold cranking studies on reference oils served as a basis for the development of a standardized laboratory test which measured an oil's viscosity under the appropriate temperature and shear rate conditions (the Cold Cranking Simulator or CCS). However, when the original CCS method (Apparent Viscosity of Engine Oils at Low Temperature Using the Cold-Cranking Simulator, D 2602) was modified to reflect a change from single temperature determinations (-18°C) to a multi-temperature method, concerns regarding test precision and the response of viscoelastic oils prevented the revision of the method to an ASTM standard. The recent development of modified CCS procedures to address these concerns has been somewhat hindered by the lack of available reference oils with supporting engine cranking data. To address this need, Esso Petroleum Canada initiated a limited study of engine cold cranking on four test oils, in 1987. Five different late model passenger cars equipped with 4- and 6-cylinder gasoline engines were subjected to repeated cold starts at temperatures between -15°C and -25°C in an All-Weather Chassis Dynamometer facility. The vehicle cranking results and samples of the test oils were forwarded to the CCS task force in 1987. More recently, Esso Petroleum Canada has undertaken a detailed cold start/pumpability evaluation of multigrade engine oils in three different heavy duty trucks. Cold cranking data from these diesel engines, in addition to the previous gasoline engine studies are discussed with respect to oil viscosity, operating temperature and vehicle effects.

Download or read book The Role of Engine Oil Viscosity in Low Temperature Cranking and Starting written by Sam Stuart and published by Elsevier. This book was released on 2013-10-22 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Role of Engine Oil Viscosity in Low Temperature Cranking and Starting, Volume 10 presents the methods for measuring the low temperature viscosity of engine oils that would correlate with the Coordinating Research Council (CRC) engine test results. This book discusses the historical background, technical progress, and the role of engine oil viscosity in low temperature cranking and starting of engines. Organized into 18 chapters, this volume starts with an overview of the importance of oil viscosity in cold starting. This text then discusses the major effects and other factors that play a part in cold starting, including oil viscosity, oil pumpability, battery condition, fuel volatility, ignition efficiency, engine clearances, and starter motor characteristics. Other chapters consider the progress in motor oil whereby multiple viscosity graded oils are capable of meeting two of more SAE viscosity grades that introduced some technical problems. The final chapter deals with the development of a reciprocating viscometer. Automotive engineers will find this book useful.

Download or read book Technologies and Approaches to Reducing the Fuel Consumption of Medium and Heavy Duty Vehicles written by National Research Council and published by National Academies Press. This book was released on 2010-07-30 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Technologies and Approaches to Reducing the Fuel Consumption of Medium- and Heavy-Duty Vehicles evaluates various technologies and methods that could improve the fuel economy of medium- and heavy-duty vehicles, such as tractor-trailers, transit buses, and work trucks. The book also recommends approaches that federal agencies could use to regulate these vehicles' fuel consumption. Currently there are no fuel consumption standards for such vehicles, which account for about 26 percent of the transportation fuel used in the U.S. The miles-per-gallon measure used to regulate the fuel economy of passenger cars. is not appropriate for medium- and heavy-duty vehicles, which are designed above all to carry loads efficiently. Instead, any regulation of medium- and heavy-duty vehicles should use a metric that reflects the efficiency with which a vehicle moves goods or passengers, such as gallons per ton-mile, a unit that reflects the amount of fuel a vehicle would use to carry a ton of goods one mile. This is called load-specific fuel consumption (LSFC). The book estimates the improvements that various technologies could achieve over the next decade in seven vehicle types. For example, using advanced diesel engines in tractor-trailers could lower their fuel consumption by up to 20 percent by 2020, and improved aerodynamics could yield an 11 percent reduction. Hybrid powertrains could lower the fuel consumption of vehicles that stop frequently, such as garbage trucks and transit buses, by as much 35 percent in the same time frame.
