In order to find method to form strong turbulence at end of compression stroke in engine, RICEM (Rapid Intake Compression Expansion Machine) has been developed. It is able to measure discriminately turbulence flow during intake or compression stroke. And then turbulence flow was measured by using a Hot wire anemometer. The results are as follows: Turbulence by inertia effect is a major portion during early intake stroke. But the turbulence by inertia effect is less than that by inlet pressure during compression stroke, because of abrupt dissipation after formation. The turbulence formed by piston compression is insignificant during compression stroke.
