 | The ignition delay times of 42 different fuels were measured in a constant voulume combustion bomb. The measurements were performed at three different initial air temperatures using fuels ranging from the primary reference fuels for cetane rating to complex mixtures of coal-derived liquids. A single-cylinder, variable compression-ratio, direct-injection diesel engine was designed and constructed to study the ignition quality of 17 of the 42 fuels. The total ignition delay times ... |

|
| Four diesel injection systems were selected for evaluating the effects of fuel properties on diesel spray characteristics. The selected injection systems were from the following Navy engines: the Detroit Diesel Allison 4-53T, the Detroit Diesel Allison 4-71TI, the Cummins NH-220, and the Westerbeke 4-108. Fuel properties which were examined were viscosity and specific gravity. The injection systems were operated on nine test fuels covering a broad range of viscosity and ... |

|
| The program described in this report was a brief survey of existing information on alternative fuels for the medium-speed class of diesel engines that is used on Corps of Engineer dredges. The alternative fuels of main interest were alcohols, vegetable oils, and liquid coal fuels. Available literature were reviewed and, where information was lacking, predictions were made of the effects of the candidate fuels on engine performance, wear and durability. ... |

|
| An investigation of the effects of alcohol fuels on spark ignition engine wear and deposition was jointly sponsored by the U.S. Department of Energy and the U.S. Army Mobility Equipment Research and Development Command. Tests were conducted using neat methanol. anhydrous ethanol, and alcohol blends as fuel in a 2.3-liter engine using a modified ASTM Sequence V-D test procedure. This dynamometer testing indicates that alcohol fuels reduce the buildup of ... |

|
 | A facility for examining shale fuel property-related combustion/ ignition effects on diesel engine performance has been installed at the U.S. Army Fuels and Lubricants Research Laboratory (AFLRL). The facility consists of a single-cylinder conversion of a three-cylinder, two-stroke cycle engine, an engine instrumentation package for determining combustion efficiencies, and a dedicated system for rapid data acquisition. The computer system and software has been developed with the flexibility to expand into ... |

|
| Research into the effects of alcohol on engine lubrication and wear has investigated four alcohol-containing fuels; pure methanol, pure ethanol, methanol in unleaded gasoline, and ethanol, in unleaded gasoline. This research work has indicated that during low-temperature engine operations such as winter commuter service and warmup, use of pure methanol may result in increased engine wear. This increased wear appears to be primarily a low-temperature problem. With the engine warmed ... |
