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

Agreed.
These DPF systems may be problematic at the moment But it shouldn't take too long before the "Bugs" are ironed out of them.
Much like all the other pollution devices that are now fitted to cars that now work seamlessly that were cause for concern when they were first introduced, The DPF systems will evolve in time.

my 2 cents, and i admit ive got a few knowledge holes on the subject.

over the last 20 years, both petrol and diesel engines have been improving. power, emissions, etc etc
petrol engines are not getting more complicated.
diesel engines are getting more complicated, though DPF's, EGR's etc,
and these accessories cause issues over time.

not sure where im going with this. is diesel running out of innovations?

I think the ICE is running out of innovations

IMHO.... yes just flapping my gums and no more...

DPF equipped diesels.
*Its not some new voodoo technology, been used in the heavy vehicle and equipment industry for what 15 years or so.
*Heavy vehicles such as trucks are more dependent on the driver pulling over and doing a manual regen cycle.
*Toyota Coaster mini buses have been DPF equipped way longer than any service people even knew it, no big issues.
*If ignored long enough even trucks will go into limp or restricted mode when the DPf (or DPD) gets too blocked.
*Vehicles such as some Jeep diesels have been DPF equipped since 2005, no big issues.
*A lack of knowledge in the light vehicle motor industry is the biggest issue with DPF equipped vehicles. I get plenty of DPF equipped vehicles that have been to the dealer with a diagnosis of needing the DPF replaced at a cost of anywhere from $6000 - $11000, ALL have been rectified without the need to replace or delete the DPF.

Diesel powered vehicles.
*ALL diesel engines suffer oil dilution, intakes gumming up, soot build up if used for light loads, short runs such as inner city commuting.
*ALL engines suffer when used in the above manner, as previously mentioned, inner city runs equates to arduous conditions.
*Modern petrol engines in the same model vehicle will often return equal to better fuel consumption as the diesel model when used in inner city driving. A new Jeep Wrangler JK (current model Jeep) in a Petrol gets on average around 11/100km which equals the diesel version around town.
*In general you can bet the petrol model will be more reliable and cost less during your time of ownership.
*Petrol is generally cheaper to buy and petrol models are often cheaper to buy.
*There are many advantages of owning/driving a diesel powered vehicle, just inner city commuting ISNT one of them.

Hail to saving the planet.
*Motor vehicle emissions account for something like 6% of Australia's emission output (correct me as needed), how about we turn off coal fired power stations and stop exporting coal, Australia would be the greenest nation on the planet.
*Yay to charging your EV from the electricity grid powered by a gas or coal fired power station.
*Toughen up emission standards on old trucks doing inner city deliveries, or better yet get rid of them all.
*Fuso have a production hybrid electric truck designed for inner city deliveries.
*Just pop down to Repco, Veales etc etc and buy a part for you Tesla car.... thats right, you cant, in fact try buying any part for your Tesla car from Tesla without it being installed by an authorised Tesla repairer. The cost of such repairs?

Care bear comments
*"there is a move within the motor vehicle industry to ask customers their intended use of a vehicle and to not sell a diesel if not suited for the purpose" is total bull****. The only move in the motor vehicle industry is to sell motor vehicles at any cost and after the sale to get that new car back to the service department thus maintaining their 60% profit margins (figures from ACCC).

Under Tesla’s warranty and guaranteed buy back value I wouldn’t have an issue taking Tesla back to Tesla.

I wouldn’t want just any mechanic working on it, ever... it’s not a car - it’s a Mobile IT system capable of hauling people. Unless you’re an Electrician (for the voltages involved) or an Electronics engineer there isn’t a lot on there for a Mechanic.

Not just a Tesla,even a Hybrid such as the RR,will need mechanics with electrical qualifications.
It uses 240V to charge,to start with,yet alone the operating system within the vehicle.

Back to school for motor mechanics....

Just the bits that wear out on other cars, like brakes, and suspension components and steering ball joints, etc.

Regenerative (electrical) braking saves on brakes to the extent that many owners will never need a pad replacement.
