What is Rolling coal?

     I am assuming that quite a few of you were confused when i began to talk about this new truck rend called rolling coal.  First, in order to explain why it is happening, i would like to discuss what is going on in the truck to make it happen.

     It used to be that seeing coal roll was limited to just massive semi trailers straining to pull massive weights up to speed.  The large contributor to this happening was the fact that much more than the normal amount of diesel was being injected into the cylinders and not all of it was being ignited.  Thus, the un-burned fuel exited the smoke stacks with the rest of the exhaust as a semi burned black soot.

      Truck drivers all across the nation have adopted this as their new form of protest against new environmental laws that have been passes as of recent.  There are kits that are able to be purchased on line that go into the computer of the truck and trick the engine into thinking that it is being deprived of fuel.  When these modifying kits are paired with things like upgraded intake manifolds, larger injectors, and upgraded exhaust systems, these trucks can produce some serious soot, and power as well.  Now, technically this is illegal in many states and is likely to be frowned upon in others, this doesn't stop truck drivers at all.  In fact, they embrace it so much that they have begun to make clubs where local coal rollers will meet and go on cruises just to roll coal down the open road.

      Now, there are some misconceptions about rolling coal that i would like to address as well.  There are instances where rolling coal is a good thing.  For instance if a drag racer wants to put a turbo diesel motor in their car for obvious torque advantages, then they need to be able to spool up the turbos at the line in order to take advantage of the full potential of the turbos.  A result of these turbos being spooled up in a diesel motor is a lot of soot spewing from the exhaust, but the results include some of the fastest passes in drag racing for non-nitro methane cars.  Another misconception is that when you roll coal, you are releasing this horrible and deadly plume of smoke with mustard gas capabilities.  However the smoke is simply half or un-burned diesel fuel that escapes with the exhaust.  Now I do not recommend that you plant your face in front of the nearest coal roller, but I am saying that it is not as bad as some people think.
