The efficiency of a modern computer controlled diesel engine runs

sort of S-I engine, LPG, gasoline, or CNG.


So why can't they figure out how to build non-smoking school buses?


None of our school buses smoke. Perhaps your local bus barn is using
old worn out buses?


Nope, except for some old ones (the hump-back variety) they look new.
Some of them brand-new. Actually, the really old ones tend to smoke less.


Now that sounds like lowest price and really old, out of date, contract
requirements. Some government agencies respond to being forced to use
lowest bid price contracting, by using "guilding the lily" type
requirements / specifications. Some other agencies just put up with crap
purchases. Others do other things.


Many of them (Thomas brand) look like they can't be older than a few years. Yet they belch plumes of soot. The drill here is: If you just washed your car and a school bus approaches an intersection before you, stop and pretend you have to wait for someone. Until it's gone.
