DCP stands for Dry Chemical Powder, which is inside the extinguisher and is the actual fire suppressant. Basically, DCP is a type of ABC Extinguisher. You can also get extinguishers for Type D (combustible metals), Type K (kitchen), and other specialized extinguishing agents (i.e. Halon). Or you can get a Type A extinguisher, AB, B, BC, ABC, and others even!
Nitrogen can be used in fire extinguishers as gas propellant.
Nitrogen or Argon depending on the type.
basically in DCP (dry chemical powder) fire extinguishers mono ammoniumphosphate is used. but some more chemicals compound are also used e.g. sodium bicarbonate, potassium bicarbonate, pottasium chloride etc.
N2, you know nitrogen gas
There is equipment that connects from the gas tank to the fire extinguisher, and is deigned to keep from overpressurizing the extinguisher. Do NOT try this without the equipment.
Because nitrogen gas bigest quantity in air.
Since petroleum is a flammable liquid, a Class B fire extinguisher would be used.
