[Stoves] PM emissions from engines

[Crispin Pemberton-Pigott]

Regarding the recent stories about diesel engines putting out much more PM than was thought (not sure who was doing the thinking) I see there is more to it than VW software cheating:

This throws even more confusion on the subject, gasoline engines produce more PM than diesel engines, presumably running on standard fuels.

If they were to run on wood gas, or gasified charcoal‎ would both of them do better?

Maybe making char in a stove for use as an engine fuel as previously discussed is a ‎way to surprise everyone.

From
‎https://cleantechnica.com/2017/05/29/gas-cars-much-dirtier-expected/

"The laboratory studied the emissions of 7 gas engine vehicles equipped with direct-fuel-injection systems. The research found that they emit from 10 to 100 times more particulates than modern diesel engines. In fact, they have higher particulate emissions than older diesel without particulate filters.‎"

So there is no 'clean fuel' after all. What about cars running on biogas and LPG and CNG?

‎Regards
Crispin
