Moreover, the glow plug unevenly heats the charge increasing thermal stratification. The increased thermal stratification by the glow plug elongates combustion. Therefore, the glow plug can provide some control over the burn rate in HCCI. The UHC and NOx emissions are also slightly improved with the glow plug. ARTICLE I NFO ABSTRACT Keywords: The effects of a glow plug on the gas temperature distribution prior to ignition in HCCI combustion are in- Thermal stratification vestigated. Two custom sleeve adapters were constructed to allow the glow plug access to the gasoline engine in HCCI combustion two different locations. The results show that increasing the glow plug voltage causes combustion to advance, Heat release which presents a method for controlling the combustion phasing in HCCI. Furthermore, the glow plug is able to Glow plug broaden the temperature distribution prior to ignition by unevenly heating the charge. This broadening of the temperature distribution decreases the heat release rate in HCCI. Therefore, an actively controlled glow plug could be used for control over the rate of heat release in HCCI, within certain limits. The effect of the glow plug on the temperature distribution is larger when the glow plug is centrally mounted with a longer penetration into the chamber. Additionally, it was found that swirl causes the uneven heating effect of the...
