That, my friends, is not just a giant, coincidentally filthy pipe in the back of that truck. It is, in fact, the exhaust. Proof? Note the lack of exhaust under the carriage. It's got to come out some place. And when it does come out, it's black as coal.
This douche drives around my town. Maybe next time I see HER, I'll snap a photo of the billowy black smoke she dumps every time she accelerates.
::stepping down off my soap box::
The diesel engine has the highest thermal efficiency of any regular internal or external combustion engine due to its very high compression ratio. Low-speed diesel engines (as used in ships and other applications where overall engine weight is relatively unimportant) often have a thermal efficiency which exceeds 50 percent.
ReplyDeleteDiesel engines are manufactured in two stroke and four stroke versions. They were originally used as a more efficient replacement for stationary steam engines. Since the 1910s they have been used in submarines and ships. Use in locomotives, large trucks and electric generating plants followed later. In the 1930s, they slowly began to be used in a few automobiles. Since the 1970s, the use of diesel engines in larger on-road and off-road vehicles in the USA increased. As of 2007, about 50 percent of all new car sales in Europe are diesel. Are they all idiots too?
What's up with all the annoying bumper stickers too? I've seen some pretty big exhaust pipes, but not that big.
