Garrett Electric Boosting Systems (EBS) Program

Description: Turbo diesel engine use in passenger cars in Europe has resulted in 30-50% improvement in fuel economy. Diesel engine application is particularly suitable for US because of vehicle size and duty cycle patterns. Adopting this technology for use in the US presents two issues--emissions and driveability. Emissions reduction technology is being well addressed with advanced turbocharging, fuel injection and catalytic aftertreatment systems One way to address driveability is to eliminate turbo lag an… more

Solar Pilot Plant, Phase I. Quarterly report No. 5, October--December 1976

Description: Collector subsystem research experiment (SRE) tests were conducted and the data evaluated. Assembly of the SRE steam generator was almost complete. Testing will start in January 1977. Two major changes in the baseline design, sensible thermal heat storage rather than phase-change storage and wet rather than dry cooling of the condenser, were being worked. Analytical and design work on the electrical generation subsystem and plant integration progressed satisfactorily.

Survey mirrors and lenses and their required surface accuracy. Semiannual technical progress report, September 15, 1978-April 15, 1979

Description: Since the beginning of widespread research and development for solar energy, a major concern has been the effect of optical and surface quality of collector materials on collector performance and the changes in these properties due to environmental conditions. In many instances, this type of data has not been compiled. When data is available on surface quality, mirror or lens optical characteristics, surface deformations due to stress and other errors, it is difficult to quantify the effect the… more

Textile drying using solarized can dryers to demonstrate the application of solar energy to industrial drying or dehydration processes, Phase II. Final report

Description: This program has resulted in the installation of a solar energy collection system for providing process heat to a textile drying process. The solar collection subsystem uses 700 square meters (7500 square feet) of parabolic trough, single-axis tracking, concentrating collectors to heat water in a high temperature water (HTW) loop. The solar collectors nominally generate 193/sup 0/C (380/sup 0/F) water with the HTW loop at 1.9 x 10/sup 6/ Pa (275 psi). A steam generator is fueled with the HTW an… more
