DMF - Petrol and diesels? - Mr Moo
Use of dual mass flywheels on diesels is now commonplace and has the potential to give rise to well documented problems.

I thought I read somewhere that they are also used (or starting to be used) with some petrol engines? Does anybody have any insights?

Will a DMF in a petrol last longer, as generally the torque output is lower?

There also seem to be a few modern diesels that don't use a DMF and instead rely on electronics to smooth things out. I think the current Fiesta TDCi is an example of this.

Does anybody know of any other current diesels that a DMF-less?

Cheers

Yeah our '98 1.6 4-pot petrol golf turned out to be DMF equiped.

My understanding is that the high power output from a small number of cylinders is the reason for needing these, to smooth out the power delivery and ease strain on the crankshaft.

If it was a 6-pot, it probably wouldnt need the DMF.

Never knew about the electronics approach, that's kind cool, not least because it means less parts!

In what way does a '98 1.6 Golf have a high power output?
