Compression-ignition engine performance with undoped and doped fuel oils and alcohol mixtures

Description: From Summary: "Several fuel oils, doped fuel oils, and mixtures of alcohol and fuel oil were tested in a high-speed, single-cylinder, compression-ignition engine to determine power output, fuel consumption, and ignition and combustion characteristics. Fuel oils or doped fuel oils of high octane number had shorter ignition lags, lower rates of pressure rise, and gave smoother engine operation than fuel oils or doped fuel oils of low octane number."

A Photometric Method for the Estimation of the Oil Yield of Oil Shale

Description: From abstract: "A method is presented for the distillation and photometric estimation of the oil yield of oil-bearing shales... The new method gives results similar to those obtained by the Fischer assay method in a much shorter time. The applicability of the new method to oil-bearing shale and phosphatic shale has been tested."

The Chemical Action of Oils on Single Crystals of Metals

Description: Note presenting a study of the chemical action of oils on large single crystals of metals in the presence of various gases, with special emphasis placed on the influence of crystal plane. The studies primarily have been concerned with four metals: silver, copper, lead, and iron and four types of oil: pure hydrocarbons with mineral oil as representative, oiliness agents with stearic acid as representative, chemical polishing agents with tricresyl phosphate as representative, and commercial oils with new and used aviation oils as representatives. The methods used in preparing large single crystals of various metals are briefly discussed.

Used oil disposal and recycling in the United States

Description: Used oil represents an important energy resource, which, if properly managed and reused, could lessen US dependence on imported fuels. About 1.4 million gallons of used oil is generated annually in the United States. Of that total, about 70% is recycled: 57% is used as fuel and 12% is refined. In August 1992, the US Environmental Protection Agency adopted standards for recycling of used oil, and many states also regulate used oil (six states list used oil as hazardous waste). This report reviews the sources of used oil and methods of disposition, focusing on reprocessing and re-refining. About 83% of the recycled used oil is reprocessed for use as fuel. However, concern about the level of lead in such fuel is increasing. Re-refining used oil is an environmentally friendly process that yields higher energy savings than reprocessing; however, it is more capital-intensive. Reprocessing used oil for use as fuel yields an energy savings (over disposal) of 131,130 Btu/gal, while re-refining the oil for reuse as lube oil saves 180,000 Btu/gal, an advantage of 48,870 Btu/gal. However, further research is needed to enhance re- refining and to demonstrate the quality and competitiveness of its products.

The fundamental principles of high-speed semi-diesel engines. Part 1: a general discussion of the subject of fuel injection in diesel engines and detailed descriptions of many types of injection nozzles

Description: Three questions relating to the technical progress in the utilization of heavy oils are discussed. The first question considers solid injection in high-speed automobile engines, the second concerns the development of the hot-bulb engine, and the third question relates to the need for a more thorough investigation of the processes on which the formatation of combustible, rapidly-burning mixtures depend.

The Effect of Xylidines on the Stability of an Aircraft-Engine Lubricating Oil

Description: Report presenting tests to determine the effect of xylidines on the stability of an aircraft-engine lubricating oil. The Indiana oxidation test and measurements of the oxygen absorption rate of the oil samples were performed on Navy 1120 oil, Navy 1120 oil plus 0.5 percent by weight of xylidines, and Navy 1120 oil used in piston-ring-sticking tests both with and without xylidines. Results regarding the Indiana oxidation test, the Davis oxidation test, the automatic oil-oxidation apparatus, and a laboratory inspection are provided.

Experiments With a Rotating-Cylinder Viscometer at High Shear Rates

Description: "Two straight mineral oils and a polymer-containing oil have been tested in a rotating-cylinder viscometer at high shear rates (maximum 0.25 million reciprocal seconds) and the accompanying heat effects have been investigated. The torque measurements are of low accuracy and fail to establish the moderately non-Newtonian behavior of the polymer-containing oil, but the temperature measurements, which are in good agreement with a thermal analysis, do indicate the presence of temporary viscosity decrease at high shear rates for this oil" (p. 1).

Composition of the essential oils from Rocky Mountain juniper (Juniperus scopulorum), Big sagebrush (Artemisia tridentata), and White Sage (Salvia apiana).

Description: The essential oils of Juniperus scopulorum, Artemisia tridentata, and Salvia apiana obtained by steam extraction were analyzed by GC-MS and GC-FID. For J. scopulorum, twenty-five compounds were identified which accounts for 92.43% of the oil. The primary constituents were sabinene (49.91%), {alpha}-terpinene (9.95%), and 4-terpineol (6.79%). For A. tridentata, twenty compounds were identified which accounts for 84.32% of the oil. The primary constituents were camphor (28.63%), camphene (16.88%), and 1,8-cineole (13.23%). For S. apiana, fourteen compounds were identified which accounts for 96.76% of the oil. The primary component was 1,8-cineole (60.65%).

End-of-season heating fuel report

Description: The year-end report notes that the 1991-92 heating season had lower average oil prices (retail home heating fuel) than the past two winters and prices remained relatively stable throughout the season. This year, the heating season average was $.87 per gallon, $1.05 for kerosene, and $1.33 for propane.

State of Maine residential heating oil survey: 1995--1996 season summary

Description: In Maine the cash price is surveyed, as opposed to lthe retail or charge price, as it has been identified as the price most often paid by Maine consumers. As one can see from the chart in this report, the 1995-1996 cash prices for No. 2 heating oil can be characterized as having an upward trend and much more fluctuation than last years` relatively flat line. The 1995-96 heating season started at the closing price of the previous season and for the first few weeks prices were lower than most of the 1994-95 trendline. When the weather became cooler, however, prices were on a steady incline until well into the winter. Prices leveled off for most of the rest of the season with a dramatic surge on the last week of the survey. The average statewide cash price for No. 2 heating oil this year was .861 1 cents, approximately ten cents higher than the average for 1994-1995 which was .7661 cents per gallon. It has been the observation of the SPO that during most of the 1995-1996 season, Maine`s prices showed a direct correspondence with New England rack or wholesale prices. It appeared that they never fluctuated more than 3-4 cents from each other.

Soy-Based, Water-Cooled, TC W-III Two Cycle Engine Oil

Description: The objective of this project was to achieve technical approval and commercial launch for a biodegradable soy oil-based, environmentally safe, TC W-III performance, water-cooled, two cycle engine oil. To do so would: (1) develop a new use for RBD soybean oil; (2) increase soybean utilization in North America in the range of 500 K-3.0 MM bushels; and (3) open up supply opportunities of 1.5-5.0 MM bushels worldwide. These goals have been successfully obtained.
