To improve startability of engine at low temperature, two characteristics of glow plug are needed. The first is fast heat-up charateristic that decreases the waiting time to start and the second is duralibity that stands in combustion chamber that is under the condition of high temperature, high pressure and corrosion. Metal glow plug have been used has some limit to enhance heat-up speed and duralibity at the same time, so we developed ceramic glow plug. It takes for ceramic glow plug 3 seconds on average to 800℃ . This property of ceramic glow plug is 2 times as fast as that of metal. The result of duralibity test, 1 minute on-off test under 11 voltage, shows that no sign of shortage can be observed<br/>
