Abstract

The present application relates to a glow plug for a vehicle and a control method thereof. A glow plug for a vehicle that avoids interference with injected fuel includes: a glow rod having an end protruding into the combustion chamber to selectively preheat the combustion chamber; a bellows surrounding the the heater rod to maintain the airtightness of the region where the heater rod is inserted into the combustion chamber; a piezoelectric element that selectively pulls or pushes the other end of the heater rod; and a controller that controls the piezoelectric element The deformation and the preheating of the combustion chamber by the preheating rod.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims the benefit of priority from Korean Patent Application No. 10-2017-0043592 filed with the Korean Intellectual Property Office on April 4, 2017, the entire contents of which are incorporated herein by reference. technical field [0003] The application relates to a glow plug and a control method for a vehicle. More particularly, the present application relates to a glow plug that avoids interference with injected fuel and a control method thereof. Background technique [0004] Generally, a glow plug is a device for preheating a combustion chamber of a diesel engine. [0005] In a diesel engine, fuel ignition occurs due to the heat of gas compression, so when the motor is turned on suddenly, the motor cannot be started. Therefore, after the inside of the combustion chamber is preheated to 800° C. or higher by applying electric current to the glow plug, fuel is injected for engine...
