This is a "diesel powered leaf blower".
On the way to Baguio our car was caught behind a fuel truck like you see here.
I wasn't paying all that much attention to the road as it's better for the passengers to focus on something other than driving since they have no control and the conditions are often frightening.
We were driving up a winding hill road when I first saw the leafblower effect. A higher engine rpm with slower speed demonstrated how someone on the side of the road just minding their own business could get blasted with a power shot of diesel, dust, and leaves.
You see, the exhaust discharge is in the front, not the top or the rear. Why is it exactly where it might do the most damage? Possibly to re-route the exhaust and reduce the possibility of igniting the fuel.
That's not what I believe though. I think that someone in charge of design likes the diesel leaf blower effect.
It is pretty funny to see someone get dusted. The dustee doesnt pay attention to what vehicle is driving toward them as they are walking or standing on the side of the road.
Then they see the debris flying toward them and they take cover.
