<P>PROBLEM TO BE SOLVED: To provide a NOx removing device for a vehicle using a fuel reforming means for lowering hydro carbon contained in fuel such as light gas oil with little input energy in a simple process. <P>SOLUTION: The NOx removing device has the fuel reforming means 10 equipped with a reforming tank 107 for holding light gas oil and with fine bubble introducing means 101-106 for introducing fine bubbles into the reforming tank 107 and generating a NOx reducing agent, a fuel delivering means 20, and a NOx reducing agent adding means 30 for adding the NOx reducing agent into exhaust gas. If fine bubbles of micro to nano sizes in diameter are mixed with fuel, when minute bubbles vanish, the fuel becomes high temperature and high pressure instantaneously and shock waves are generated. Hydro carbon in the fuel can be dissolved by the shock waves and lower hydro carbon of an objective molecular weight is generated. Fine bubbles are introduced in the fuel reforming means separate from the fuel tank and therefore a treating condition can be chosen without affecting fuel in a fuel tank. A cost and input energy of the device can be reduced remarkably. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
