USE OF DECOMPRESSING NATURAL GAS TO LOWER THE INTAKE AIR TEMPERATURE OF AN INTERNAL COMBUSTION ENGINE

A fuel system is comprising: a fuel tank; an internal combustion engine; a fuel regulator fluidly connecting the fuel tank to the engine, the fuel regulator being configured to reduce the pressure of the fuel from a first fuel pressure at the fuel tank to a second fuel pressure at the engine; an air supply assembly configured to supply air from an air inlet to the engine, the air assembly comprising: a first air supply line fluidly connecting the air inlet and the engine, the first air supply line being in thermal communication with the fuel regulator; a second air supply line fluidly connecting the air inlet and the engine, the second air supply line being in parallel with the first air supply line; and an air valve configured to adjust the air flowing through at least one of the first air supply line and the second air supply line.
