| Research Abstract |
A novel combustion system in which autoignition is induced by spark discharge into a pre-mixture of high cetane number fuel formed during a long ignition delay time by using a direct injection diesel engine with low compression ratio of 14 was experimentally demonstrated. As the result, it was found that the combustion timing was advanced and the combustion stability at low engine load was improved by spark induced compression ignition system.
