Test 406: John Deere R Diesel, Nebraska Tractor Test Lab

Nebraska Tractor Tests

EXPLANATION OF TEST REPORT: John Deere R Diesel

TEST A: The manufacturer's representative operates the tractor for a minimum of 12 hours using light to heavy drawbar loads in each gear.

This serves as a period for limber up, general observation and adjustments. Adjustments that are permissible include valve tappet clearance, breaker ,point gap, spark plug gaps, clutch and others of a similar nature. No new parts or accessories can be installed without having mention made of it in the report. No data' are recorded during this preliminary run except the time that the engine is operated.

Water Injection In The Modern Automotive Spark Ignition Engine, Leonard Carl Nelson Jan 1949

Water Injection In The Modern Automotive Spark Ignition Engine, Leonard Carl Nelson

Masters Theses

"The injection of water in the spark ignition engine is not new. The effect of humidity in the air on the performance of the spark ignition engine probably initiated the early investigations. The water vapor in the inlet air decreases the speed of the flame front and necessitates spark advance to assure maximum power and maximum efficiency. Water particles in the air evaporate during the compression and combustion of the inducted charge and decrease the tendency of the engine to detonate. These effects are very evident when operating the spark ignition engine in a moist atmosphere. Water is not a …

The Effect Of The Convection Coefficient On The Temperature Amplitude In Periodic Heat Flow, Gordon L. Scofield Jan 1949

The Effect Of The Convection Coefficient On The Temperature Amplitude In Periodic Heat Flow, Gordon L. Scofield

Masters Theses

"The problem to be investigated in this thesis is that of periodic heat flow in a semi-infinite solid. Periodic flow means that heat flow is a continuous function of time and repeats itself at regular intervals. A semi-infinite solid is one which is bounded by one and only one plane. This subject has received considerable attention in the field of soil temperatures, both at the surface of the earth and at various depths. The surface of the earth is subjected to temperature changes which are nearly periodic. These temperature changes take place both daily and annually. A knowledge of these …


The Application Of The Relaxation Method To The Solution Of Problems Involving The Flow Of Gases Through Porous Media, Ralph Davis Jan 1949

The Application Of The Relaxation Method To The Solution Of Problems Involving The Flow Of Gases Through Porous Media, Ralph Davis

Masters Theses

"The purpose of this investigation is to determine the feasibility of applying the relaxation method of mathematical analysis to the solution of problems involving the flow of gases through porous media. The relaxation method was first applied to two-dimensional problems by Christopherson and Southwell, who applied it to problems in stress analysis. It was later applied to steady-state heat conduction problems by H. W. Emmons and to steady-state flow of incompressible liquids by A. A. Zwierschowski. The solutions of problems involving the flow of gases through porous media is difficult for all but the simplest boundary conditions, and impractical for …
