Determination of optimum design parameters of glow plug and experimental verification

In Diesel Engines, the heat energy obtained from glow plug increases engine's ability to start up in cold climatic conditions and significantly reduces emissions of harmful gases leaving exhaust. conditions, before off diesel vehicles it is necessary wait for about 10 s cylinder block heating. This period negatively affects driving comfort. this study, mathematical results processes optimize time required reach temperature have been experimentally proven. A test apparatus was developed confirm theoretical results. Thanks these improvements concerning manufacture plug, 850 ° C has reduced by approximately 5 s. The proposed design accordance with present market. Currently whole must be changed at end lifetime, our improvement only inner tube resistance can easily involving a cost reduction 60%.
