When were dpfs introduced

[waynne]

In what year was the dreaded particulate filters introduced? Or was it phased in over a period of time by many different manufacturers?

Do all modern diesels use a DPF type filter?

They're not quite as bad as you're conveying.

The 406 2.2 HDi in 2000 was the first car thus equipped.

Larger engines for commercials and buses have used them for longer.

The later DPFs do not rely upon supplementary cerium based fuel additives to do their work.

Mine had a 6 litre additive tank adjacent to the petrol tank. The car literally monitored fuel level before/after opening the filler cap and administered the correct dosage to the tank after fuelling.

This tank had to be refilled every 60,000-70,000 miles at a cost of about £72 (ouch).

This system, although complex, did not seem to suffer with the problems that the later (and probably cheaper) systems incur.

Regeneration was always completed fully even under moderate driving.

But chucking out heavy metal cerium compounds into the atmosphere sounds, to me at least, rather more injurous to health than a bit of soot here and there.
