my truck would get about 15% better mileage if it ran leaner and created more NO, without EGR etc.
If we didn't live in clown world, where fundamental data is ignored, this would warrant further investigation, research and policy change.
“This is a pretty good model for what the world would be like if half of us were driving electric cars,” Cohen says."
"The same study found that even as NO2 emissions plummeted 60% and fine particulate matter dropped 31%, global average ozone went up slightly around the world." nb: it's not clear if he refers to low - level ozone, but afaik NO does not affect stratospheric ozone, so it can be assumed it's in reference to low-level ozone, the one that presumably causes asthma, and the reason for our vehicles running on a more rich mixture & EGR valves.
"The air pollution events in China were “a surprise for everybody,” says Aijun Ding, an atmospheric chemist at Nanjing University. After all, he says, “we almost entirely shut down the traffic and the factories.” The explanation is a nonlinear connection between nitrogen oxides (NO2 and NO) and secondary pollutants such as ozone."
