Capacitive Pressure Sensor System and Packaging

Pressure sensors play an important role in engine maintenance and monitoring systems by diagnosing problems before they happen. To capture the most accurate data, however, these sensors must be...

Ducted Fuel Injection for Soot Reduction

Typical direct-injection engines, such as diesel engines, can produce soot due to fuel-rich combustion conditions. Filters and catalytic converters are currently used to reduce soot and harmful...

Multi-Axis Motion Controller Accelerates Gear Testing

Materials testing and characterization is often a lengthy process. It can take more than a year and billions of testing cycles for a manufacturer to characterize the properties of a new...

Engines for Remotely Piloted Atmospheric-Science Airplanes

A spark-ignited reciprocating gasoline engine, intake-pressurized with three cascaded stages of turbocharging, was selected by NASA's Environmental Research Aircraft and Sensor...
