2019 Sprinter Revealed

[SiennaGuy]

I admit that I'm hung up on the dashboard for the new Sprinter. It's the part of the vehicle that I'd spend hours looking at if I owned one, so it makes a big difference to me.

In some of the new videos, they show a parking assist feature in the dash. I'm hoping that this option is offered on RVs. Although it's designed for parallel parking on a street, it could make trying to get into a tight campground parking space much easier. You wouldn't need a sidekick outside yelling, "Turn... turn... Stop!" If it could also be used at highway speeds to check for cars and motorcycles in blind spots, it would be ideal.

So great, now what? Does that mean more or less problems?

Why should he have to mention DEF? It's a given for keeping the DPF from failing. Aussies generally have more relaxed emission standards but not for this component. Any way you look at it, it's a wretched bandaid that invites all sorts of expensive unintended consequences.

Actually, as I understand it, this isn't quite true. The DEF is injected downstream of the DPF. They are independent systems that perform different functions.

I do not disagree with your larger sentiment, though.

Putting it in perspective since I was in Australia last month, Australia only has 24 million people in about the size of the 48 states in the USA. I doubt they would have as much concern. I did get an ambulance ride in a Sprinter in Sydney.

Thanks for the correction. If that's the case then I have it wrong. My understanding was that for the DPF to do its job, DEF had to be injected.

You inject diesel into the DPF

You inject DEF into the SCR


Pretty well ALL the diesel engines use this method,
including GM, Ford, Cumin...


WHAT IS SCR?

I see my mistake. I thought DEF was introduced into the DPF but it's introduced downstream of the DPF into the catalytic converter to eliminate NO. Isn't NO a product of both diesel and gas engines and since gassers are also required to reduce NO emission, how is that accomplished without using a system similar to diesel DEF?

[avanti]

Diesel engines produce much more NOx than do petrol engines, for a variety of arcane reasons, mostly having to do with higher combustion temperatures and the thermodynamics of the direct-injection of the fuel.

I have said before DIFFERENT standards.US Diesels are illegal in Australia and Europe ,as it is difference emphasis of Euro 5/ 6 on CO2, CO and particulates
Woman who wrote the article in a vague way agreed we do not have Euro 6.
In other words a Euro 5 compliant diesel in Australia cannot be used in Europe.
Similarly a US Tier compliant Sprinter Diesel is illegal in Europe! and also in Australia

You would be pretty wrong on that score. I know Australia is pretty clean compared to many places in the US, but State and Federal Governments would like to keep it that way.
So they are in the process of introducing Euro 6 .Many new heavy truck diesels run Euro 6 already.

How did we arrive at this mess?

My take -- all these will become history soon.
This is just too damn complicated for any good.

How is NOx eliminated in current gas engines? Is the level sufficiently low that it can be addressed by the catalytic converter or is the permitted NOx discharge level different for gas and diesels?

[SiennaGuy]

I brought up DEF fluid. I was trying to show that the Australian emissions system that John Cadogan was talking about in his YouTube video is not the same one as we have in the US. I have no idea if the system required in the US is better or worse in any regard, but I wanted folks to take his words with a grain of salt. He's not talking about American cars. Some things may apply, but I don't think that it's a good idea to generalize that all cars built for any market are all the same, whether or not they have the same model name.

IIRC they reduce the NOx with the EGR system to reduce peak flame temps.

Could not be more correct

It is odd that they didn't announce a mild hybrid for the Sprinter. They have it in the E and S-classes. Mild hybrids provide assist during cold start and periods of high demand, helping with emissions. And of course, a 48V factory charger would simplify house battery charging considerably.
