Each step in the evolution of the casting design of Chrysler's 2.0-liter/four-cylinder gray iron engine block is modeled using Technalysis' finite element metal casting analysis program PASSAGE®/PowerCAST. The effect of different gating designs are investigated to determine the variations in temperature distribution and solidification time. Three different casting designs are evaluated by comparing the results of the numerical simulations.

The development process of a water pump impeller used on a sport utility vehicle engine is described. A review of the design process is presented in this paper including the computer-aided flow analysis together with testing procedures. By computer modeling, one can estimate the coolant flow characteristics of a given impeller blade shape for providing increased cooling performance and improved efficiency on the engine. It also provides directions for the improved design. The test data are used specifically to confirm the analysis results.

Licensing technology has long been established a viable means for helping both parties of such an agreement improve their technology bases. The licensor/licensee relationship must be close and interactive to optimize these improvements. The importance of the selection process of potential licensees as well as the structuring of how the technology is transferred are key items for the success of license agreements. Future licensing activities may require tighter controls on technology transfers to protect against the creation of new competitors.
