DEVICE FOR REDUCING NOX BY VAPORIZATION GAS COMBUSTOR

摘要

PURPOSE: A NOx reducing device by using vaporization gas combustor is provided to improve the durability of a combustion gas valve for reducing the generation of NOx by resupplying vaporization gas collected by a canister to a cylinder after burning the gas in a vaporization gas combustor. CONSTITUTION: A NOx reducing device by using vaporization gas combustor includes a vaporization gas combustor(30) connected to a purge control solenoid valve(24) which controls the supply of vaporization gas passed through a canister(38) connected to a fuel tank(34) via a tube way for collecting the vaporization gas, and controlled by a signal of an electronic control unit(28), and a combustion gas valve(32) for controlling the supply of the combustion gas burned in the vaporization gas combustor with respect to an intake tube(26) according to a signal of the electronic control unit.
