Fiesta diesel econetic C-DPF. How does it work?
I'm looking for a new car for my wife and the new fiesta looks good. There's have a choice of a 1.4 and a 1.6 diesel engine, both do 63
MPG and emitt 110g of CO2, which is nice - you might as well have the bigger one.
Then there's the 1.6 ECOnetic, which seems to be exactly the same 1.6 diesel with a coated diesel particulate filter. This somehow reduces the
CO2 emissions to 98g, which is good and somehow believable. It also increases the MPG to 76.
How does that work then? How does a particulate filter add 9 MPG, given that the torque and power figures are the same?

what do you do with all the filtered particulates? does a lump of carbon fall out the back every few hundred miles?

it waits until your doing a steady speed at fairly high rpm, like on the motor way. and then adds a chemical to the fuel to burn it off into something
else...
theres about 3 different DPF's, i think the plated type is the best.

I suspect that the power figures are for the base engine and not taking account od the particulate filter.
Incidently, I've just taken delivery of a new 1.6 TDCi fiesta this week, cracking car and a big improvement over the last model.

The Eco model will almost certainly be running on skinny tyres, and may have different gearbox to help it along.

eco
the eco fiesta has narrower tyres diffrent gear oil ,a spoiler to reduce drag on the front etc all designed to reduce the aerodynamics and use less
fuel but at an extra cost .Dpf systems put a special oil through the cat after so many drive cycles and cleans out the soot,what a lot of people dont
relise they have a service life and cost a fortune to replace

A guy I work with had some trouble with the MIL light coming on on his Peugeot. He took it to the dealer who plugged his machine in and told him it
needed a new cat and DPF. A new cat was about a billion pounds and the DPF 5 billion pounds. He had a word with one of the guys in the workshops who
told him to take the DPC off the car and bake it in an oven for a couple of hours and then put it back on the car. Once fitted, rev the car hard for
10 minutes. He did all this and took the car to have the MIL put out and it's been no bother since!!!
