Towards HCCI Control by Ozone Seeding

摘要: Nowadays, the main objectives in automobile engine field are to reduce fuel consumption and pollutant emissions. HCCI engines can be a good solution meet emission requirements achieve high combustion efficiency. However, before an is used as conventional engine, several problems must overcome, particular control of progression combustion. Many studies have been conducted into possible methods. A new strategy consists using oxidizing chemical species such ozone seed intake engine. As increasingly smaller ozonizers now being designed, this kind device could integrated on vehicle order phasing promote future use In present study, experiments fuelled with iso-octane were carried out seeding intake. Results showed that when assisted by addition ozone, enhanced moved forward. Consequently, means Depending inlet temperature, may more or less easy due sensitivity concentration. The results also show existence cool flame case combustion, indicating study
