Thread: DPF's the end of diesel cars in cities?

Nothing new in that.

The best vehicle for an urbanite is electric.
The short runs do nothing for the longevity of an internal combustion engine.

In fact short urban trips constitutes ‘arduous conditions’ and should be serviced more frequently than those doing long runs out country.

Have a look at these:

The DPF engined diesels cars are both a wonder and a mystery to which they happily turn a blind eye to when buying. It is only when their dash lights up and the car goes into limp mode that their bubble bursts.

Depends on the vehicle. Many can have a manual regeneration started, and some only need a mild run.
Others need a long run.
And then there’s some that can regenerate idling.

The best thing for these urbanites is to be told to run a vehicle at least once a week on a decent run.
The old Sunday drive was good for keeping the old cars from fouling plugs, carbonised pistons etc..

Yep, I just did 2000 km's in a 3 month old Toyota Commuter Diesel van with DPF in NZ and at one point the gauge on the dash showed half full, drove to the shops the next morning and it must have regenerated while idling. In fact over those 2000 km's I noticed it regenerated multiple times, whether driving highway or not, the gauge would sometimes empty.

The biggest issue I could imagine with this in a 4x4 is while driving over long grass, you don't want to ignite it, the sticker on the dash warns to clear the area of ignition sources before hitting the regenerate button on the dash, while idling, and yet if it's doing it automatically you can't control that risk.

Some people have to learn the hard way.

If they don't research what they are buying properly,well then thats their issue.

Another major issue is this oil dilution problem that is occurring in some brands.

one of our firetrucks has DPF. we've had it 5 years and done only 15,000km. its mostly short trips and period of long idling.
the burn takes only a few minutes.
i dont think short trips are an issue for it.

As I said. Depends on the programming logic.

Our work Twin Steer Water Cart regenerative cycles are
Short and much more frequent than the Merc Engines in the Terbergs.
