Abstract
There are many reports, which are related to ""Effect of Combustion Chamber Deposit (CCD) on emissions from multipoint injection gasoline engine,'' but a few reports related to ""Effect of CCD on emissions from direct injection gasoline engine.'' In this paper, the relationship between CCD and emissions from direct injection gasoline engine in vehicle was investigated. The emission data for each step on 10-15 mode were analyzed in detail. In addition, the effect of gasoline detergent on DI-CCD was investigated.
