Vans, diesel engines & DIESEL PARTICULATE FILTER (DPF)

[Midwest]

This subject has been mentioned before (wirepuller talked of it), but it won't hurt to mention it again (Fawlty Tower Style!) for those thinking of a new van (or car).

I've been looking for a new used vehicle; was thinking of getting some sort of Chelsea tractor, one of which was a Discovery Sport (DS). After reading about it on a particular forum, it appears to have an issue with the above.

To meet Euro 6 emissions (I'll stand to be technically corrected), a DPF is used to trap some of the nasty stuff. In the DS's case, its a bit of a challenge, and requires some mileage driven at a certain speed to do so (as do most such vehicles). Put in a short journey when it is attempting a regeneration, and turning off the car dumps some fuel in the sump, causing another issue, oil dilution.

Too many failed regenerations, will require vehicle servicing or even possibly repairs. The oil dilution is another problem.

So those buying/leasing new diesel vans would be ok, if they do some mileage, those doing short journeys might wish to reconsider the fuel choice for their new vehicle.

This guy had to sign a waver when purchasing a new diesel Ford Connect (Zedman);

rubbish. this is a proper diesel engine.

The two stroke Detroit Diesel took a bit of beating too.

I'll see your Gardner and raise you a Deltic...

not diesels, but a treat to hear anyway.

A Simple New Exhaust Technology Could Save The Diesel Engine

As market trends threaten to put a premature end to the diesel engine, researchers at a British university have developed a miraculous saviour

Researchers have developed a technology that could virtually eliminate the problem of harmful nitrogen oxides from combustion engines, suggesting the possibility of a combustion-powered car that barely emits more harmful particulates than an EV.

British boffins at Loughborough University have reportedly reached such a successful stage in their project that its new technology is nullifying 98 per cent of toxic diesel NOx emissions even before being tuned for best results. That’s like throwing an engine together in your garage and discovering that it’s immediately producing 600bhp.

The latest revisions to diesel engines haven't been enough
ACCT, or Ammonia Creation and Conversion Technology, uses Ammonia to separate nitrogen and oxygen. The molecules of the latter are attached to hydrogen instead, leaving no waste products other than nitrogen, which makes up around 78 per cent of Earth’s atmosphere, and common water.

At present, NOx particles, which are produced predominantly by diesel engines, especially when hot, are linked to the premature deaths of around 71,000 people across the continent every year. Four years ago the AdBlue system was introduced; a urea-based solution that helped exhausts burn off much more of the particulate matter. ACCT knocks AdBlue into row Z.

There's life in the old dog yet!
In early tests, the simple and cheap ACCT prototype was fitted to a diesel Skoda taxi, which focused on stop-start urban driving. While the standard, Euro 6-compatible AdBlue system captured 60 per cent of the particulates, the un-tuned ACCT hit 98 per cent right off the bat.

AdBlue’s effectiveness is limited by climate and operating conditions, but ACCT is said to work at almost peak efficiency at all times. You can imagine how valuable this sort of thing could be in a European car market that has seen diesel sales plunge 20 per cent.

Earth Dreams could soon get much dreamier
Car makers, component manufacturers and even large fleet operators are apparently besieging Loughborough University to try to get their hands on the tech as soon as physically possible, according to Autocar.

The engineering team thinks it should be easy enough to integrate the technology into cars as they are today, and it could be in production within two years “with the right support,” by which they presumably mean money, and access to car and parts makers’ production processes. This could theoretically draw a lot more life out of combustion, easing the rush to electrify everything…

Ah, Tel...that is indeed a beauty! So many amazing boats powered by those. The 6LX was a favourite. Good to know you can get them refurbished too

Kelvin made nice little engines too.

was that when his kitchen fitting business was quiet?

Think Kevin was never into diesel engines!
Kelvin however, slightly older,born 1904 and still going strong, was never into kitchens...

I had one lke this in a boat many years ago

except it was a 2 cylinder, so 2 of these stuck together.
Easy to start-just open the decompression levers, crank the handle til you built up a bit of revs, then pop the handles down one by one...never failed.

BTW, it didn't have a DPF...

As a kid I found the BR deltic trains mesmerising.
