HIGH-SPEED, HIGH-OUTPUT, LOOP-SCAVENGED TWO-CYCLE DIESEL ENGINES
1957-01-01
570062
THIS paper deals with the problems connected with high-speed loop-scavenged 2-stroke diesel engines. The theoretical processes of scavenging are described, and methods for their calculation are discussed. It is shown that it is possible to predetermine, to a considerable extent, the most important characteristic values of scavenging and, thus, to shorten the development work. Various arrangements for the supercharging of 2-stroke engines are treated, and the problem of turbocharging this type of engine is described.

WHERE DOES ALL THE POWER GO?
1957-01-01
570058
AS a basis for the analyses of this symposium, a hypothetical car has been used to evaluate the engine power distribution in performance. Effects of fuel,-engine accessories, and certain car accessories are evaluated. The role of the transmission in making engine power useful at normal car speeds is also discussed. Variables encountered in wind and rolling resistance determinations are reevaluated by improved test techniques. Net horsepower of the car in terms of acceleration, passing ability and grade capability are also summarized.

MYTHS AND FALLACIES OF AUTOMATION
1957-01-01
570061
THIS PAPER discusses the myths and fallacies regarding automation. According to the author, there is no such thing as an “automatic” factory, but merely degrees of automation. Advantages of automation are discussed in detail, especially in regard to productivity increases and labor displacement.

ELECTROJECTOR—BENDIX ELECTRONIC FUEL INJECTION SYSTEM
1957-01-01
570060
THIS paper discusses the new Electrojector which is Bendix's answer to the fuel injection problem for passenger-car installation. Their approach includes an electronically controlled and electrically actuated system. Details of this fuel injection system, such as the solenoid valves, are given here. Fuel supply to the engine during performance, especially in cold weather, is evaluated.

Temperature-Strength-Time Relationships in Mufflers and for Truck Muffler Materials
1957-01-01
570055
DATA presented in this paper show temperature-time diagrams obtained from mufflers mounted on trucks which were traveling over their regular routes. Using these temperature data, specimens made of possible muffler materials were subjected to laboratory tests. A wide range of possible muffler materials and gas composition were covered in these tests. Results of the tests indicate that under long-run heavy-duty truck service, muffler failure occurs primarily because of high metal temperatures and that coated mild steel showed the most promise of longer muffler life.

HIGH-SPEED TURBOPUMPS
1957-01-01
570054
SELECTION and general design considerations of the components for high-speed, high-performance turbopumps are discussed here. A simple mathematical example of aerodynamic theory is presented for pump and turbine design. The author discusses choice of design for the specific performance desired. Considerations of numerous factors influence selection. Example of a typical high-speed turbopump is given based on the theory developed here.

THE AUTOMOTIVE GAS TURBINE - Today and Tomorrow
1957-01-01
570057
THIS paper discusses the progress of research on the automotive gas turbine and predicts its future potentialities. Comparison of gas turbines and presently used engines shows the possibilities of the gas-turbine applications. Design, construction, and testing of gas turbines are discussed, especially in the light of economy and performance.

EFFECT OF FUEL VOLATILITY ON STARTING AND WARMUP OF NEW AUTOMOBILES
1957-01-01
570056
A COOPERATIVE study of the relationships between fuel volatility and the cold-starting and warmup performance of late-model passenger cars has been carried out by Standard Oil Co. (Indiana) and Ethyl Corp. Tests were made on seven 1956 passenger cars in an all-weather chassis dynamometer room at ambient temperatures of +40 to −20 F. Fuel volatility was varied over a broad range. Warmup characteristics and sensitivity to fuel volatility varied widely among the cars tested. A comparison of the results of this program with earlier test programs indicated that the modern V-8 engine is more critical to fuel volatility than its in-line predecessors.

EFFECT OF VACUUM MELTING ON LOW ALLOY STEELS
1957-01-01
570342
The paper describes improvements obtained in mechanical properties of low alloy steels as a result of vacuum melting. It gives tensile, impact and fatigue properties of vacuum melted 4340 and UHS 260 steels and compares them with those of air melted material.
