Wrenched diesels for 10 years.
The "green" movement people fall for is nothing more than a money grab.
The old non EPA busses I worked on would get 10ish mpg sometimes 12
The EPA compliant busses achieved about 6 sometimes 8mpg
Not to mention all the extra pollution added in shipping and manufacter of all the dpf/def components. Think mining platinum is good for the environment?
Think injecting urea into exhaust is good for the environment?
EPA diesels we're about 40% of our fleet and caused about 85% of the breakdowns.
Think the manufacture and shipping of all them extra parts reduces pollution?
Look at the big picture.
All your looking at is 1 tree, not the whole forest
You're probably too young to remember what the air in cities used to be like. It was bad. It was unhealthy. It smelled bad. Every so often, living in rust-free California, I find myself behind a pre-smog muscle car, its 7 liter engine pumping out semi-burned hydrocarbons, and I remember what it used to be like - ALL cars pumping that **** out all the time they were running. Diesels pumping out huge clouds of particulates loaded with carcinogenic chemicals from incomplete combustion.
You say I can't see the forest for the trees? Dude, you didn't used to be able to see the forest, because of the smog.
And, yes, injecting urea reduces nitrogen oxide pollution, which used to be one of the biggest contributors to photochemical smog - the kind that made LA and other places so famously smoggy.
