Development Of A Test For Rapid Determination Of Octane Ratings Of Gasolines, Charles B. Gangwer
Development Of A Test For Rapid Determination Of Octane Ratings Of Gasolines, Charles B. Gangwer
Mechanical Engineering ETDs
For many years, the Mechanical Engineering Department of the University of New Mexico has been interested in developing a more reliable and expedient method to determine octane readings of gasolines than the conventional CFR Motor Method of Test for Knock Characteristics of Motor Fuels. A summary of the development of the conventional CFR Test method and a brief discussion of the operational procedure of this method is necessary to better understand the need for a new fuel rating procedure. To further explain the disadvantages of the conventional test method, an introduction to the new test method to be developed will …
The Design, Construction, And Calibration Of A Stationary Wave Device For Determining Sound Absorption Coefficients Of Acoustic Materials, Douglas W. Ballard
The Design, Construction, And Calibration Of A Stationary Wave Device For Determining Sound Absorption Coefficients Of Acoustic Materials, Douglas W. Ballard
Mechanical Engineering ETDs
The general scope of the thesis investigation is limited to the engineering design and construction of a stationary-wave device for the experimental determination of the sound absorption coefficients of various building materials, the calibration of the apparatus to give comparisons with results obtained in the more expensive reverberation method, and to attempt to correlate observed results with generally accepted acoustical standards.
Development Of Electro-Mechanical Equipment For The Measurement Of Knock Characteristics Of Gasolines, Rudolph W. Ebacher
Development Of Electro-Mechanical Equipment For The Measurement Of Knock Characteristics Of Gasolines, Rudolph W. Ebacher
Mechanical Engineering ETDs
It was considered by the writer that characteristics of oscilloscope wave forms representing the varying pressures taking place in the CFR engine cylinder might provide an index to octane ratings of gasoline. Obtaining pressure wave forms on the oscilloscope required some medium for providing an electrical signal in response to engine cylinder pressures. A quartz pressure element was considered as the item that could fulfill this requirement.
