Diesel particulate filter: effective?

[Woodcutter]

[...] Finally ... a priori even PSA the king of Diesel is changing its tune for small engines! (is this the Euro6 effect?)

"changing their minds for small engines", you mean they are going to abandon small cars with diesel engines? [...]

I mean that PSA is, finally (!), In the process of designing small high-tech petrol engines (small displacement, turbo, direct injection) to make city cars consuming very little. This is progress, even if they could go directly to electric ...

I know a good particle filter, tested recently:

in addition, 10% of SP 95 in diesel reduces particulate emissions by 50%

and we have just seen it recently, the recirculation of the burnt gases (50% of steam) eliminates totally particle emission

It is silly to buy a small fuel oil for the city but people do it (70% you said it) because they are oxen who follow the herd and go to the slaughterhouse, like the others!

Ah sheep you mean

On a boiler yes (I recall the links of the excellent works of Maloche: https://www.econologie.com/une-chaudiere ... -3830.html ) ... on an engine we know the disadvantages of the Egr ...

Yep, that's because the EGR valve works on all or nothing instead of being proportional to the amount of fuel.

I will not delay doing a test with an EGR valve permanently open at 30% to check the "opacimetry" of the fumes as I have already done here https://www.econologie.com/forums/economies- ... 1-140.html with different fuel combinations

the ideal would be to recover only the water vapor to reinject it; the principle of the GV what!

Besides, on this subject, Fly and the other GV users could not do this little opacimetry test with and without water injection to get an idea? please?

Hello Capt_Maloche

It is under study ... without water, with water, and with the propylene glycol mixture. Not now...
A+

The great Charles said oxen ... Balavoine took it up a little later.
