I agree but for all the straight through pipes its going to be a nightmare!! For the record DPFs in my opinion are a waste of space and cause more pollution than they save a better way has to be found or diesels are dead
So how exactly do you stop the particulates from being formed in the first place from diesel combustion?
If they could do this via optimum engine tuning they would have done so by now!
The Dpf was the only solution to this problem! The problem was that it was badly implemented and this was not the manufacturers fault.
The engineers had to come up with something that would fulfill the requirements of Euro V, and be done in a short time frame.
The systems are getting better as time goes on as shown by the 2.0 jtdm having it's Dpf nearer to a heat source! I.e the engine! Hence why it seems to have less issues.
The hotter the Dpf is ,the better is is at burning off particulates come regeneration time.
What I struggle to understand is why they have not encased the Dpf in ceramic or some other insulator that preserves the heat. Much like how a storage heater works!
I read somewhere that the Multiair technology is going to ported to Diesel engines in the near future. Apparently not for extra economy, but they predict that the system can produce such a clean burn that a Dpf will no longer be needed! Let's hope eh?
