I stand (extremely) corrected; I assumed that diesels were less environmentally damaging. I believe catalytic converters in SI cars produce high levels of NOx. I also worked for 12 years in diesel machine underground mines and with a lot of very large machines, and we never came close to PM or gas occupational exposure limits even in poorly ventilated areas. BUT I am not well informed (merely opinionated my wife tells me) in this field, so I apologise for my assumption. And I will keep an eye out for a new thread on this topic, sorry to have helped so much to hijack this one.
