As a result of widely increasing air pollution throughout the world & vehicle emissions having a major contribution towards the same, it makes its very essential to engineer or design an alternative to the present traditional gasoline vehicles. Liquid nitrogen fueled vehicles can act as an excellent alternative for the same. Liquefied N2 at cryogenic temperatures can replace conventional fuels in cryogenic heat engines used as a propellant. The ambient temperature of the surrounding vaporizes the liquid form of N2 under pressure & leads to the formation of compressed N2 gas. This gas actuates a pneumatic motor. A combination of multiple reheat open Rankine cycle & closed Brayton cycle are involved in the process to make use of liquid N2 as a non-polluting fuel. A system of such a kind will also be able to refuel itself in a matter of time comparable to that of traditional engines, unlike the electrically charged ones.
