(Direct fuel injection) Gas powered cars now are emitting more particulates , which arguably are worse for people than the smog of the 60s because they penetrate deep into the lungs and can even enter the bloodstream (I am paraphrasing) . https://www.sciencedirect.com/science/article/abs/pii/S0048969720308123 https://www.sciencedirect.com/science/article/abs/pii/S00489... https://pubmed.ncbi.nlm.nih.gov/32109813/ https://pubmed.ncbi.nlm.nih.gov/32109813/ IMHO gasoline Particulate filters (GPF) for gas vehicles should be mandatory the way they are for diesels (DPF).

> Gas powered cars now are emitting more particulates We mostly solved that for diesels with particulate filters, I assume the same could be done for gas engines?

> "with significant emissions occurring in the first 3 min of operation" I'm guessing that's because once the catalytic converter heats up it burns most of the carbon particulates.
