Faced with increasing concern for lubricating, oil consumption and engine friction, it is critical to understand the oil transport mechanisms in the power cylinder system. Lubricating oil travels through distinct regions along the piston ring pack before being consumed in the combustion chamber, with the oil distribution and dominant driving forces varying substantially for each of these regions. This experimental work focuses on specific regions in the piston ring pack. A detailed 2D LIF (Two Dimensional Laser Induced Fluorescence) study has been performed on the oil distribution observed with the LIF generated real time high-resolution images, as were changes in piston and ring design. The results reveal the third land, located between the second compression ring and the oil control ring, oil flow patterns and timing are consistent and predictable at each operating point. Speed and load variation alter the basic flow pattern and oil balance through a corresponding change in inertia and gas dragging effect respectively, with ring design variation instigating specific and repeatable phenomenon onto the consistent oil flow pattern. Second land, the region between the top two compression rings, geometric and flow patterns throughout the entire cycle of a single cylinder spark ignition engine. The impact of speed and load were experimentally changes were found to have a significant impact on inertia driven oil transport; however...

Anodic bonding is a common process used in MicroElectroMechanical Systems (MEMS) device fabrication and packaging. Polycrystalline chemical vapor deposited (CVD) silicon carbide (SiC) is emerging as a new MEMS device and packaging material because of its excellent material properties including high strength, hardness, and thermal conductivity. An alternative, low temperature glass to CVD SiC anodic bonding process is required in order to prevent gold tin braze stress relaxation. A novel process recipe, requiring a SiC RMS surface roughness of 45nm, was developed for anodically bonding CVD SiC to bulk and thin-film, lapped Pyrex[TM] and Hoya SD-2[TM] glass substrates. The bond quality, residual curvature, and microstructured interfacial features for CVD SiC anodic bonding were shown to be comparable to single crystal silicon (Si) anodic bonding. The Plaza Test specimen, invented by Plaza et al., was used to assess bulk and thin-film, lapped glass bond quality. A two-part contact/bonding model was used to predict the contact and bonding of the Plaza Test structures. Surface contact was predicted by a parallel plate capacitor pull-in model after the voltage was applied, and linear elastic fracture mechanics (FEA) modeling predicted the toughness or work-of-adhesion of the bonded surfaces after the formation of a permanent silicon dioxide bond. The role of the voltage...
