No - it is not subject to fuel tax, is not used to power the vehicle, and does not go into the fuel tank (it has a separate tank).
DEF (diesel exhaust fluid) is used as a consumable in SCR (selective catalytic reduction) in order to lower NOx concentration in the diesel exhaust emissions from diesel engines.

No. They have other exhaust regulation devices, such as the EGR (exhaust gas regulator), DPF (diesel particulate filter), and DEF (diesel exhaust fluid).
There are many benefits of a diesel exhaust or DEF diesel exhaust fluid. It is very efficient and it has lower concentrations of nitrogen in the fumes which it releases. It is an aqueous urea solution with 67.5% of it deionised water.
No.No.
The working fluid in an internal combustion engine like a diesel would simply be the air it sucks in and passes out in the exhaust.
It is a solution of pure water and 32.5% urea. It is injected into the exhaust stream to lower emissions.
Already been done. Diesel Particulate Filters and Diesel Exhaust Fluid.

No, the Mercedes Sprinter did not start using diesel emissions fluid until the 2010 model year.
To determine if a truck is diesel-powered, you can check the fuel cap or fuel door for labels indicating diesel fuel, look for a diesel exhaust fluid (DEF) tank, or listen for a louder engine noise and a distinctive diesel engine sound when the truck is running.
Some of it wasn't by their design... the switch to Ultra Low Sulphur Diesel in 2007, for instance. For the remainder, Cummins uses an aftertreatment system, consisting of a Diesel Particulate Filter, Diesel Exhaust Fluid dosing, and Selective Catalytic Reduction.
