A pseudo-slow motion video system has been used to directly image gasoline transport in the intake system of four engines. Injector spray pattern, location, and timing are all shown to have a strong influence on the wetting and washing of the intake valves. These parameters are strongly correlated with base fuel and additive performance: increasing valve wetting and washing result in better additive performance and lower valve deposit levels.
