CHARACTERIZATION OF HYDRAULIC INTERACTIONS BETWEEN TORQUE CONVERTER AND TRANSMISSION DURING TRANSIENT EVENTS

A torque converter was instrumented with 29 pressure transducers to measure the torus, clutch plate, and torque converter cavities using telemetry to transfer the data. The torque converter was placed in a six-speed front wheel drive transmission and a test cell was built to drive and load the transmission to mimic in-vehicle performance. Steady state tests were completed to establish a baseline for pressure performance of the torque converter. The transient events tested include back drive and gear shifting. Back drive showed how the pressure fluctuates across the speed ratios above 1 as well as identifying the stator speed. Gear shifting presented how large the pressure change can be between each gear state. Low speed downshifting, where hydraulic demand can possibly exceed pump capacity, resulted in showing the control over the torque converter clutch was still possible and reliable. These results can be used to improve future calibrations and designs

Oil spill source identification using colorimetric detection

The colorimetric detection of polycyclic aromatic hydrocarbons (PAHs) was investigated for the quick and easy identification of likely oil spill offenders. In this new technology, photochromic compounds were used to sense PAHs by varying their photoswitching capacity. To that end, three photochromes were designed and showed varying degrees of photoswitching inhibition depending on PAH analyte, photochrome and excitation wavelength. PAH mixtures that mimic oil spills showed the same varying response and demonstrated the accuracy of this technology. To prove the applicability of this technology, an array was assembled using the three photochromes at three excitation wavelengths and tested against authentic crude oil samples. Not only could these samples be differentiated, weathering of two distinctly different oil samples showed limited variation in response, demonstrating that this may be a viable technique for in situ oil identification
