OBD-Heavy duty vehicles

Postby ravim on Sat Aug 27, 2011 12:06 am

I would like to get clarifications for european heavy duty OBD:
1. Whether "Misfire" monitoring is required for heavy duty CNG vehicles?
2. Whether NOX sensor is mandatory for EOBD stage-I for heavy duty diesel vehicles equipped with SCR systems? Or is it be possible to comply with EOBD stage I requirements only with urea quality sensor?
