Development of a Hybrid Vehicle Powertrain Test Laboratory
… tested a fully functional eddy-current chassis dynamometer testing facility on campus. An automotive test facility requires a systems engineering approach to install, calibrate and commission a chassis dynamometer. This thesis shows that, the dynamometer test facility was successfully installed, …

Investigation of Plasma Electrolytic Oxidation (PEO) Coated Bores in Internal Combustion Engines
… on PEO in cylinder bores. Through fired-engine dynamometer testing, it was determined that large piston-to-bore clearance distances, increased oil retention, and a small dispersed surface porosity morphology created a tribological environment which produced improved wear resistance of PEO …

Development of a high efficiency dilute gasoline engine
… implemented to protect the second engine. Engine dynamometer testing was conducted on the second engine in single Diesel injection pulse operating mode and resulting emissions and fuel consumption data were compared to stock engine performance information. Testing of HEDGE operation was not …

Effects of artificial neural networks characterization on prediction of diesel engine emissions
… performed on a 550 hp General Electric DC engine dynamometer-testing unit at the West Virginia University Alternative Fuels, Engine and Emissions Research Center. The 3-Layer and Jump Connection networks were the most promising architectures and it was found that the radial basis functions such as …

Experimental Evaluation of JP-8-Based Fire Resistant Fuels
… by Luna Innovations to a final set of five FRF. Dynamometer testing was used to determine peak power of the supplied Yanmar 2V750 engine. Fuel fire resistance characteristics were defined and compared using a rotating disk anti-misting characterization system. Fuels were characterized based upon …

A comparison of bi-directional disc brake rotor passage designs
… particularly for high performance applications. Dynamometer testing showed that respectable increases in braking performance are achievable with relatively simple machining modifications. Tuft and smoke visualization techniques provided a preliminary understanding of the airflow in the passages …

Comparisons of countermovement jump and isokinetic performance in youth athletes: maturation and early sport specialization considerations
… completing countermovement jumps and isokinetic dynamometer testing. Since most current research concludes that being a single sport athlete leads to negative affects more research needs to be completed since in this study the subjects did outperform the multiple sport athletes. Future research …

Understanding the challenges in HEV 5-cycle fuel economy calculations based on dynamometer test data
EPA testing methods for calculation of fuel economy label ratings, which were revised beginning in 2008, use equations that weight the contributions of fuel consumption results from multiple dynamometer tests to synthesize city and highway estimates that reflect average U.S. driving patterns. The …

Investigation of Emissions and Fuel Economy for the Integrated Bus Information System
… data used in this study were based on chassis dynamometer testing conducted by West Virginia University (WVU), considering that chassis dynamometer test cycles could reflect the actual vehicle operations.;Many factors affect emissions and fuel economy, including vehicle parameters, fuel type, …
