Abstract
A glow plug of a vehicle preventing an interference with an injected fuel includes a preheating rod having one end protruding to the combustion chamber to selectively preheat the combustion chamber; a bellows pipe enclosing the preheating rod to maintain an air-tightness of an area where the preheating rod is inserted to the combustion chamber; a piezo element selectively pulling or pushing another end of the preheating rod; and a controller controlling a deformation of the piezo element and the preheating of the combustion chamber through the preheating rod.
