NOx sensor helps make engines cleaner

Delphi Automotive Systems and Electricore are developing a low cost, commercially viable automotive nitrogen oxide (NOx) sensor.

Delphi Automotive Systems and Electricore have been selected to receive a cost sharing research award from the United States Department of Energy (DOE) for approximately $1.85 million to develop a low cost, commercially viable automotive nitrogen oxide (NOx) sensor.

The NOx sensor will monitor emissions of NOx in the modern Compression-Ignition, Direct- Injection (CIDI) engine, enabling the control of combustion and implementation of advanced exhaust emission control systems.

This award is part of the DOE’s Research and Development and Analysis for Energy Efficient Technologies in Transportation and Buildings Applications Program. It is part of a previously announced program by US Secretary of Energy Spencer Abraham, that will award approximately $110 million to organisations and universities performing research and development on cutting-edge energy efficiency and clean energy science and technology.

The transportation technology developments as part of this program support the implementation of DOE’s Office of Advanced Automotive Technologies (OAAT) R&D Plan.

The goal of OAAT is to develop technologies for a new generation of vehicles that will achieve fuel economies up to three times those of comparable family sedans by taking advantage of the inherent high efficiency of the CIDI engine in a hybrid electric vehicle, while meeting all applicable federal environmental standards.
