Coc or nox of nissan skyline

[drifter17a]

live in the UK, and London has introduced a Low Emission Zone (LEZ) that requires individuals to pay £13 if their car doesn’t meet the required emissions standards.

 

The standard specifies that NOx emissions must be less than 0.08 g/km (i.e., the vehicle must meet Euro 4 standards or better, which generally results in NOx levels of around 0.08 grams per kilometer).

 

I reached out to Nissan UK, and they advised me to contact Nissan Japan directly. Does anyone have contact details for Nissan Japan or any certifications of conformity that show the emission details or NOx levels for the RB25DET engine?

 

Any guidance would be greatly appreciated.

No, but they will be WAAAAAAY too high. You will never get your ticket.

I presume it would take more than just slapping a big modern catalyst on the exhaust?

It's interesting though, looking at the old sales brochures and listings it does not mention anything about emissions. No one cared.

If you're driving something like an R32 through to R34, no chance of meeting Euro4.

Euro4 came out in 2006, and car manufacturers back then were complaining how hard it would be to meet those regulations. Not a chance a vehicle 10 years earlier is going to be compliant.

Well, I have my IM240 results with a cammed LS1...

My Nox was 0.11 and my CO g/km was 0.2.

Euro4 is 0.08 and 0.1 respectively. I'm gonna say for a stock RB this is actually plausible, BUT in Australia they were complied pre-Euro2, so the limits were:



Which as you can see, is way higher. I'd say a stock RB with a new OEM Cat could? actually pass Euro4 for NOX but you'd probably have to do a hell of a lot of testing to prove it, and getting a car emissions tested and carrying a certificate of emissions when/if you get pulled over may be cost prohibitive if it's even allowable to get your car tested and re-classified.

You'd have to find out what the UK Govt is using as reference material. It may be non-negotiable.

Having a read online, need to get the emission standard from their logbook, or the manufacturer as to what Euro it meets.

If it doesn't meet it, you can modify the car to meet it, and then go through a big government process.

 

As vehicle is pre Euro4, it won't be meeting it.

 

I'd honestly doubt anything but the NEO motors have a chance of getting near the EURO4.

NEO is specifically for getting better emissions.

Would it be possible to meet these emission standards on e85?
