At present you will notice no MOT statutory requirement [or ability perhaps] to routinely measure NOx levels during the test other than registering the ability of any Adblue [urea] system fitted to function = presence of fluid ? and absence of engine warning lights for faulty NOx sensors? Thus emission testing still essentially relies on the manufacturers declared NOx reduction figures. This might change in the future as focus appears to continue to move away from CO2 emisssions slightly to particulates and NOx. Its taken MOT testing a while to catch up with DPF removal but I expect they will eventually catch up with any modification designed to circumvent NOx emisssion levels also.
Its interesting that there must have been a trade-off of CO2 emissions V NOx emissions by the regulatory authorities because a reduction in engine thermal efficiency and consequent drop in MPG would imply an increased CO2 per miles travelled in the real world.![Confused :confused: :confused:](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f615.png)
