Several different automobile windows were tested for transmission of noise Bench-scale flow noise tests, full-scale wind tunnel flow noise tests, and acoustic tests were performed The windows tested were the front side windows of a Chrysler sedan The transmission of external airborne noise was measured in a hemianechoic chamber at the Chrysler Technical Center A loudspeaker was used as a white noise source The transmission of the white noise into the vehicle interior was measured Aeroacoustic or flow noise tests were performed in the Chrysler Wind Tunnel in Chelsea, Michigan The test car was placed in a 112 km/hour flow and the resulting flow-induced noise was measured in the vehicle interior Bench-scale flow noise tests were performed at the Cornell University Low Noise Wind Tunnel, using the same set of window constructions The paper describes the results of all three types of tests The bench-scale test data from the Cornell University Wind Tunnel correlated well with the corresponding data measured in the Chrysler wind tunnel

The technologies of recycling Reaction Injection Molded (RIM) polyurethane polymers have been refined to the stage of commercial reality. Chrysler Corporation is in the process of qualifying the use of automotive fascia containing recycled RIM thermoset polymers. This will mark the first use, in North America, of a recycled RIM thermoset polymer into a class A surface exterior automotive part. This was made possible through a close working relationship with Polyrim Green Lane, a division of Decoma International, and Dow Plastics. The described process technology allows the recycle of painted and unpainted process scrap, and potentially post consumer scrap, into the same application without the loss of surface quality or polymer performance. This will divert these materials from the waste stream that is currently being landfilled.

An advanced multi-domain CFD analysis approach is proposed to calculate the scavenging flow process in motored two-stroke engines. An implicit and conservative treatment at the domain interface is developed which offers significant speedup in convergence. An arbitrary Lagrangian-Eulerian approach for moving grid and a grid remeshing technique for grid sliding at engine cylinder/transfer ports interfaces are used for efficiency and accuracy. A three-dimensional simulation of the Mercury Marine research two-stroke engine is carried out to demonstrate the approach. Six computational domains are used which naturally represent the geometries of the cylinder, engine dome, exhaust and transfer ports. The influence of boost port inclination angle on the scavenging process of the two-stroke engine is also studied numerically. The computation is supplemented with a standard two-equation turbulence model with compressibility correction.

General laboratory and testing procedures employed by the Chrysler Corporation in the development of its automotive gas turbine powerplant are discussed, with particular emphasis on facilities, instrumentation requirements, component fixtures, and complete powerplant tests. Some specific development problems and their solutions are presented along with some performance test results.

Both conventional and newly developed materials used in unique applications have played an important role in making the Chrysler gas turbine engine a practical powerplant. The new low-cost materials developed by Chrysler Metallurgical Research include, (a) a series of iron-base super alloys having equivalent or superior life to aircraft type alloys, (b) heat resisting iron aluminum alloys for elevated temperature service under low stress application, and (c) long life rubbing seal materials that operate satisfactorily from ambient temperature up to 1200°F and above. These materials appear to meet all present or immediate high temperature alloy requirements for a competitive mass produced automotive turbine.

A chemical approach and simple test apparatus are combined to study engine distributor cap deterioration. This paper describes a convenient test which correlates qualitatively with other tests and field experience. The apparatus produces an environment which is similar to that found in use under severe conditions. With this apparatus, critical experiments were performed. Moisture and electrical stress appear to be the major factors in cap deterioration.

Paper is concerned with continuous data analysis using analog computer techniques. The author discusses briefly some of the possible techniques available. There are many variations or, and ramifications to, the circuits discussed. The type of analysis, the author points out, is an integral and important part of the design of any experiment.
