Abstract

Motivated by automotive emission legislations, a Virtual NOx sensor is developed. This virtual sensor consists of a realtime,
phenomenological model that computes engine-out NOx by using the measured in-cylinder pressure signal from a
single cylinder as its main input. The implementation is made on a Field Programmable Gate Array–Central Processing
Unit architecture to ensure the NOx computation is ready at the end of the combustion cycle. The Virtual NOx sensor
is tested and validated on an EURO-VI Heavy-Duty Diesel engine platform. The Virtual NOx sensor is proven to meet
the accuracy of a production NOx sensor for steady-state conditions and has better frequency response compared to
the production NOx sensor.
