Torque Converter Testing Challenges
In the development of a torque converter, there are several engineering parameters on each of the internal components that must be understood: temperatures, fluid pressures, strains, and potential cavitation.
In torque converters, the stator, turbine, and clutch are rotating inside of the pump and cover, which is also rotating inside the transmission housing. This presents a big challenge to get data off each component using an inductively powered, wireless telemetry system. IR Telemetrics has…
The Need for New Measurement Capabilities
In the complicated matrix of oil flow passages in a diesel engine, little is typically known about the actual oil flow through different passages within the crankshaft and connecting rods. Typically, oil pressure in the main block gallery is monitored, and assumptions are made that the flow is sufficient to the bearings. These flows are critical to the lubrication of crankshaft main bearings, rod journal bearings, and piston pin bearings.
The oil flow through a connecting rod for a…
