NASA 1996 SBIR Phase I


PROPOSAL NUMBER : 96-1 02.02-7115

PROJECT TITLE : : Miniaturized Lamba Sensors for Engine Control Systems

TECHNICAL ABSTRACT (LIMIT 200 WORDS)

Advanced engine control technologies require small and light Lambda sensors that can reliably detect air to fuel ratio (A/F) in the engine exhaust stream to enhance fuel economy and reduce engine emissions. Existing sensors have several inherent limitations which make them unsuitable for such applications. Nanomaterials Research Corporation (NRC) proposes to develop miniaturized Lambda sensors from nanomaterials that can address the existing problems. The sensor will be based on nanostructured Ga2O3 ceramics. The innovation can dramatically reduce the size, weight, and power-consumption of the sensor while maintaining enhanced sensitivity, response time, and high temperature usability that make them extremely useful for space and commercial applications. During Phase I, the proof-of-concept will be demonstrated. Phase II will optimize and field test the sensor, while Phase III will commercialize the technology.
POTENTIAL COMMERCIAL APPLICATIONS
NASA can significantly benefit from small, light, and low-power-requiring sensors. The proposed sensor can enable more efficient, low pollution, high performance envelop operation of combustion engines that drive space vehicles, aircrafts, and logistic support infrastructure. Spin-off applications include the new generation chemical sensors that help to improve the fuel economy and emission control for automotives, natural gas engines, diesel based engines, and stationary combustion units.
