Yea the engine burns off the particulates, I'm not exactly sure what the preferred method for that is.

The main particulate problem I think actually comes from lower load, where the injector is only spraying on the compression stroke. You get a lot of unburned fuel that way. Under heavy load, most of the fuel is sprayed on the intake stroke and mixes with the air better.

Sometimes I kind of like how port injection is so simple...

Particulates form because only the exterior of the fuel droplet gets exposed to air and doesn't have time to fully atomize, so the center doesn't fully burn and chars.

It used to be mostly a Diesel issue, until direct injection became widespread on gassers too...

I wonder if there's a way to utilize the electric portion of a hybrid drive-train to keep super efficient engine designs in their regulation compliant pollution zones? For instance if it's heavy loads that cause it to fall out of compliance, just eliminate heavy loads and compensate with electricity for the short duration of accelerating or climbing a hill.
Not sure if that would be so easy with a parallel hybrid, but that's the point for serial hybrids.
