The present invention relates to an exhaust gas cleaning device for a diesel vehicle using exhaust heat and ultrasonic waves. A fuel is preheated by the exhaust gas heat of an exhaust pipe through which exhaust gas is transferred. The preheated fuel is supplied to an ultrasonic wave carburetor. The preheated gas is vaporized and atomized by ultrasonic waves of the ultrasonic wave carburetor, and the fuel is mixed with the outside air. The mixed fuel and air is injected into a fuel/air injecting device to easily combust fuel so that the liquid fuel which is not evaporated is completely removed from the device. Therefore, the exhaust gas cleaning device for a diesel vehicle using exhaust heat and ultrasonic waves is able to solve the problem of melting down a diesel oxide catalyst device and an exhaust gas reduction device due to the locally generated heat and can prevent a particulate matter and pollutant, which are not purified due to loss of a filter function, from being exhausted into the air.
