Abstract In recent years, it suffers from environmental problems such as global warming and air pollution. The exhaust gas of the car is referred as one of causes of air pollution. Therefore, it is necessary to control the in-cylinder gas flow to decrease exhaust gas. Moreover, the gas flow generated in cylinder is decided under the intake condition. In this research, the port model to imitate a real engine intake port is used to examine the in-cylinder gas flow. In-cylinder gas flow was measured how it was changed by two kinds of port shape in this port model by using flow visualization in color layer. As a result, it was roughly understood that the state of the in-cylinder gas flow changes by the difference ofthe port shape and the amount of the valve lift. Moreover, it was made an evaluation two kinds of port shape.
