MikeAqua:

 

 

 

It seem to me that the solution to local pollution is local regulation - e.g. emission standards for cars that may enter a particular city.   

 

 

I don't think that's practical.

 

     

  1. To enforce it, a cop has to be able to identify whether a car is compliant. Will each city issue each compliant car with a sticker?
  2. There's economies of scale; it's much easier to design and build a fix into every car
  3. Adding after-market emission controls to some cars would be expensive and difficult
  4. Whilst it's convenient that the wind blows pollution away, it doesn't actually stop it causing harm
  5. Local government has vested interests in local industry, and therefore in allowing pollution to occur

Sidestep:

 

Because our market's too small to develop complex emissions reduction systems just for us, the NZTA accepts emissions standards from the USA, Japan and Europe as a proxy.
They aren't specifically designed for New Zealand. If they were NOx would likely be lower on the list.

 

 

It would be easy for the NZ government to set it's own NOx emissions levels. All it has to do is allow higher NOx emissions levels, and specify that other emissions can't be any worse than the Euro 5 (or the current relevant standard). So overseas compliant cars can still be imported "as is". Yet manufacturers would be able to offer customised models to NZ if they want. In most cases the only thing needed would be different ECU firmware.

 

As for the Volkswagen and other cars that were part of the so called emissions cheating scandal. Lets face it, those cars would still have lower emissions than most of the older cars still on NZ roads. And they would have far better crash safety as well. NZ should have allowed them to be imported, We would have still gotten an overall emissions reduction. And there would have been a reduction in the road toll and other costs related to car crashes like ACC and hospital costs due to less injuries.

Aredwood:

 

 

 

My understanding is that Volkswagen no longer make FSI engines as they had high NOx emissions. Also other manufactures like Honda no longer make their VTEC-E engines. Or other engine technologies that were designed to give better fuel economy by running lean air fuel ratios during light load cruising.

 

 

 

 

The FSI acronym is just a logo.

 

Stratified injection is standard direct petrol injection tech.

 

Lean burn is needed to meet CO2 and economy standards/claims.
