Are engine revs raised during DPF regeneration?

Are engine revs raised during DPF regeneration on a Nissan Qashqai?

No. Extra diesel fuel is post-injected into the engine to ignite the DPF and burn off the soot during active regeneration, but engine revs should not rise. What you might experience is the radiator cooling fan running hard and continuing to run after you switch off the engine because of the extreme heat.

I read a lot about diesel DPFs but how do I know when the fuel system is regenerating? I drive a Toyota RAV4 2.2-litre diesel. Nothing comes alight on the dash board and only once did I smell hot oil?
Does active regeneration of the DPF happen automatically? And should I put additives into the fuel?
After repeated short drives in a diesel does DPF regeneration make a noise and raise the engine rpm?
