The induction swirl in a spark ignition engine was studied. An effective model test using water was devised which allowed observation of the induction swirl in the cylinder.First, steady flow without a piston was observed, and it was discovered that two vortexes were generated in the cylinder.Next, the flow patterns of several cylinder heads with intake ports of various shapes were observed and their relation to combustion was investigated. From the results, it was discovered that high speed and well mixed vortexes aided combustion.Experimentation with unsteady flow with a piston was also conducted.
