Heat-transfer tests of a steel cylinder barrel with aluminum fins of optimum proportions by Herman H Ellerbrock( Book )

2 editions published in 1940 in English and held by 8 WorldCat member libraries worldwide

An engine cylinder barrel with aluminum fins was tested. Later two more barrels manufactured by a method to be used in the factory production of large numberes of engines were tested. The tests showed that the thermal bonds between the aluminum fins and the aluminum base and between the aluminum base and the steel for all three barrels was very good. In addition, other tests showed that the mechanical bonds between the cylinder parts would probably be satisfactory
The effect of xylidines on the corrosiveness of aircraft-engine oil by W. T Olson( Book )

2 editions published in 1943 in English and held by 8 WorldCat member libraries worldwide

Tests were made 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 without and with xylidines. Laboratory inspections performed on used oils from the beginning and end of several piston-ring-sticking tests without and with xylidines added to the fuel and the oil are compared
Efficiency tests of a single-stage impulse turbine having an 11.0-inch pitch-line diameter wheel with air as the driving fluid by David S Gabriel( Book )

3 editions published in 1945 in English and held by 8 WorldCat member libraries worldwide

Results are presented of efficiency tests on a single-stage impulse turbine having an 11.0-inch pitch-line diameter wheel and a fabricated nozzle diaphragm using air at moderate temperatures as the driving fluid. Efficiency curves are shown for turbine pressure ratios from 1.2 to 5.2. The maximum efficiency occurred at a blade-to-jet speed ratio of approximately 0.4 and was about 0.615 for turbine pressure ratios from 3.0 to 4.6. Additional curves of the air-flow data are presented
Knock-limited performance of pure hydrocarbons blended with a base fuel in a full-scale aircraft engine cylinder. 1 - Eight paraffins, two olefins by Anthony W Jones( Book )

Correlation of the characteristics of single-cylinder and flight engines in tests of high-performance fuels in an air-cooled engine. 1 - Cooling characteristics by Robert W Wilson( Book )

2 editions published in 1945 in English and held by 6 WorldCat member libraries worldwide

Variable charger-air flow, cooling-air pressure drop, and fuel-air ratio investigations were conducted to determine the cooling characteristics of a full-scale air-cooled single cylinder on a CUE setup. The data for the same model multi-cylinder engine tested in flight in a four-engine airplane
Operating temperatures of a sodium-cooled exhaust valve as measured by a thermocouple by Julio Sanders( Book )

3 editions published in 1943 in English and held by 6 WorldCat member libraries worldwide

A thermocouple was installed in the crown of a sodium-cooled exhaust valve. The valve was then tested in an air-cooled engine cylinder and valve temperatures under various engine operating conditions were determined. A temperature of 1337 degrees F was observed at a fuel-air ratio of 0.064, a brake mean effective pressure of 179 pounds per square inch, and an engine speed of 2000 rpm. Fuel-air ratio was found to have a large influence on valve temperature, but cooling-air pressure and variation in spark advance had little effect. An increase in engine power by change of speed or mean effective pressure increased the valve temperature. It was found that the temperature of the rear spark-plug bushing was not a satisfactory indication of the temperature of the exhaust valve

Relation of preignition and knock to allowable engine temperatures by Arnold E Biermann( Book )

2 editions published in 1943 in English and held by 5 WorldCat member libraries worldwide

The results are given of an investigation of some of the limitations that now prevent increases in the temperature level of engine cylinder heads, and a review of previous work in the field is included to supplement these results. Attention was given, in particular, to the effects of fuel knock and surface ignition on cylinder temperatures and the effects of cylinder temperatures on performance. Data were obtained from a Wright C9GC air-cooled cylinder and from a Lycoming O-1230 liquid-cooled cylinder
Knock-limited performance of pure hydrocarbons blended with a base fuel in a full-scale, aircraft-engine cylinder. 3 - Four aromatics, six ethers by Anthony W Jones( Book )

2 editions published in 1946 in English and held by 5 WorldCat member libraries worldwide

Knock-limited performance tests of leaded blends of four pure aromatic hydrocarbons and six pure ethers with a base fuel were conducted in a full-scale aircraft-engine cylinder at two operating conditions to determine the antiknock effectiveness of additions of pure compounds to aviation fuels
Calculations of the performance of a compression-ignition engine-compressor turbine combination. 1 - Performance of a highly supercharged compression-ignition engine by Julio Sanders( Book )

2 editions published in 1945 in English and held by 5 WorldCat member libraries worldwide

Small high-speed single-cylinder compression-ignition engines were tested to determine their performance characteristics under high supercharging. Calculations were made on the energy available in the exhaust gas of the compression-ignition engines. The maximum power at any given maximum cylinder pressure was obtained when the compression pressure was equal to the maximum cylinder pressure. Constant-pressure combustion was found possible at an engine speed of 2200 rpm. Exhaust pressures and temperatures were determined from an analysis of indicator cards. The analysis showed that, at rich mixtures with the exhaust back pressure equal to the inlet-air pressure, there is excess energy available for driving a turbine over that required for supercharging. The presence of this excess energy indicates that a highly supercharged compression-ignition engine might be desirable as a compressor and combustion chamber for a turbine
Knocking tendency of an air-cooled aircraft-engine cylinder with one and with two spark plugs by R. C Spencer( Book )

2 editions published in 1943 in English and held by 5 WorldCat member libraries worldwide

Tests have been conducted with an air-cooled aircraft-engine cylinder to determine the effect on the knocking tendency of cutting out one spark plug when the engine is operating at or near the knock point with two spark plugs firing
The NACA balanced-diaphragm dynamometer-torque indicator by Charles S Moore( Book )

2 editions published in 1944 in English and held by 5 WorldCat member libraries worldwide

A balanced-diaphragm device for measuring dynamometer torque of single-cylinder or multi-cylinder engines is described. This device, which was developed for laboratory use, has proved to be accurate, reliable, and adaptable. Compressed air, automatically controlled, is used as the balancing and the transmitting fluid; thus, a simple method of obtaining torque measurement at a remote position is provided
Determination of gas temperatures from the frequency of knock-induced gas vibrations in an internal-combustion engine by W. E Moeckel( Book )

Small-orifice tubes for minimizing dilution in exhaust-gas samples by Harvey A Cook( Book )

2 editions published in 1943 in English and held by 5 WorldCat member libraries worldwide

An investigation was undertaken to find a means of obtaining undiluted exhaust-gas samples from a Wright R-2600-B aircraft engine equipped with short individual stacks (approximately 10 in. long). Preliminary tests to aid in determining the best design, location, and orientation of orifices ranging from a 0.002-inch slot to an 0.1875-inch-diameter circular opening at the entrance to an exhaust sampling tube were made with a small Briggs & Stratton engine. Sampling tubes 1/4 inch in diameter and with a 0.010-inch-slot orifice were installed in all 14 cylinders of the Wright engine after the correct location and orientation for the sampling tubes had been determined in tests on a single cylinder of this engine. Samples were analyzed by an Orsat portable apparatus and by an NACA mixture indicator
Heat-transfer processes in liquid-cooled engine cylinders. 1 - Correlation of single-cylinder engine temperatures under forced-convection cooling conditions by Benjamin Pinkel( Book )

2 editions published in 1945 in English and held by 5 WorldCat member libraries worldwide

An analysis based on forced-convection heat-transfer theory, similar to the analysis presented for air-cooled engines in NACA Report No. 612, is made of the cooling processes in liquid-cooled engine cylinders. Semi-empirical equations that relate the average head and barrel temperatures with the primary engine and coolant parameters are derived
The knock-limited performance of fuel blends containing aromatics. 5 - n-propylbenzene, n-butylbenzene, isobutylbenzene, m-xylene, and 1-isopropyl-4-methylbenzene by Carl L Meyer( Book )

2 editions published in 1946 in English and held by 5 WorldCat member libraries worldwide

Results are reported of knock-limited tests of five aromatics, each individually blended with selected base fuels and tested with and without TEL, using 17.6, F-4, and F-3 small-scale engines. The five aromatics rated in the following order of decreasing antiknock effectiveness at fuel/air ratio 0.10: m-xylene, 1-isopropyl-4-methylbenzene, n-propylbenzene, isobutylbenzene, and n-butylbenzene
Nitrided-steel piston rings for engines of high specific power by John H Collins( Book )

2 editions published in 1944 in English and held by 5 WorldCat member libraries worldwide

Several designs of nitrided-steel piston rings were performance-tested under variable conditions of output. The necessity of good surface finish and conformity of the ring to the bore was indicated in the first tests. Nitrided-steel rings of the same dimensions as cast-iron rings operating on the original piston were not satisfactory. The final design was a lighter, rectangular, thin face-width ring used on a piston having a maximum cross-head area and the proper skirt shape. Results were obtained from tests of single-cylinder and multicylinder engines
The effect of inlet temperature and pressure on the efficiency of a single-stage impulse turbine having a 13.2-inch pitch-line diameter wheel by Ernest R Chanes( Book )

2 editions published in 1945 in English and held by 5 WorldCat member libraries worldwide

Efficiency tests have been conducted on a single-stage impulse turbine having a 13.2-inch pitch-line diameter wheel and a cast nozzle diaphragm over a range of turbine speeds from 3000 to 17,000 rpm pressure ratios from 1.5 to 5.0, inlet total temperatures from 1200 to 2000 degrees R, and inlet total pressures from 18 to 59 inches of mercury absolute. The effect of inlet temperature and pressure on turbine efficiency for constant pressure ratio and blade-to-jet speed ratio is correlated against a factor derived from the equation for Reynolds number. The degree of correlation indicates that the change in turbine efficiency with inlet temperature and pressure for constant pressure ratio and blade-to-jet speed ratio is principally a Reynolds number test
End-zone water injection as a means of suppressing knock in a spark-ignition engine by Rinaldo J Brun( Book )

3 editions published between 1944 and 1945 in English and held by 4 WorldCat member libraries worldwide

The engine operating conditions of the tests did not simulate those encountered in flight, especially with regard to the operating speed of 570 rpm. For this reason the results should only be regarded as of theoretical importance until further investigation has been made
