Beschreibung
Zusammenfassung:	A fuel vaporizing device for a cold start-up of a vehicle is provided to start an engine normally even when the temperature of the engine is low by applying vibration to vaporize liquid fuel with a high frequency generator and a piezoelectric element. A fuel vaporizing device for a cold start-up of a vehicle comprises a fuel tank(10) storing fuel inside, a vibration generating unit installed in the fuel tank to apply vibration to fuel, a fuel collecting unit(15), such as a canister, collecting vaporized fuel generated in the fuel tank and supplying the vaporized fuel to an engine, a temperature sensor detecting temperature of the engine, and an ECU receiving a signal from the temperature sensor and operating the vibration generating unit if the detected temperature is under predetermined value. The vibration generating unit comprises a piezoelectric element(13) installed underneath the fuel tank to apply vibration to the fuel, and a high frequency generator(14) installed under the piezoelectric element to generate electric current for vibrating at high frequency.
