Nitrogen oxide -- Sensors and systems for engine management

PDF Version Also Available for Download.

Description

The goal of this Cooperative Research and Development (CRADA) effort is to further develop sensors and sensor systems in order to meet current and anticipated air emissions requirements due to the operation of Defense Program facilities and the emission standards imposed on new vehicles operating in this country. Specific objectives of this work are to be able to measure and control on-line and in real-time, emissions, engine operation, air-to-fuel intake ratios, and throttle/accelerator positions in future models of consumer automobiles. Sensor and application specific integrated circuit developments within Lockheed Martin Energy Systems are applicable to the monitoring and engine controls ... continued below

Description

The goal of this Cooperative Research and Development (CRADA) effort is to further develop sensors and sensor systems in order to meet current and anticipated air emissions requirements due to the operation of Defense Program facilities and the emission standards imposed on new vehicles operating in this country. Specific objectives of this work are to be able to measure and control on-line and in real-time, emissions, engine operation, air-to-fuel intake ratios, and throttle/accelerator positions in future models of consumer automobiles. Sensor and application specific integrated circuit developments within Lockheed Martin Energy Systems are applicable to the monitoring and engine controls needed by General Motors. In the case of emissions sensors, base technology in thick/thin film sensors and optical systems will be further developed to address the combination of high temperature and accumulated deposits expected in the exhaust stream. Other technologies will also be explored to measure fuel-to-air ratios and technologies such as fiber optic and acoustic wave devices that are applicable to the combustion sensing on an individual base. Two non-contact rotary position sensors have been developed for use in control-by-wire throttle control applications. The two CRADA developed sensors consist of a non-contact, differential capacitance position transducer and a custom complementary metal oxide semiconductor (C-MOS) application specific integrated circuit (ASIC) suitable for use in both passenger and engine compartments.
