The tendency of spark ignition direct injection (SIDI) engines to form injector deposits was investigated using engine dynamometer tests on a SIDI engine equipped with fan spray type injectors. Fifteen test fuels with varying 90% distillation temperature (T90), aromatics, olefins, oxygenates and sulfur levels were prepared to identify the effects of fuel properties on injector deposits. The results suggested that not only the T90 but also the number of alkyl substituent of aromatics had effects on injector deposit formation. Effects of detergents on the injector deposit cleanliness were also evaluated in this study.
