PIV is a method that used to obtain instantaneous velocity measurements of the swirl flow which contributes to the uniform mixing of air and fuel in a diesel engine. This paper came to investigate the effect of dual port on gas flow model by using a high-speed PIV in a CI engine under various engine speeds. It reveals the significant factor of inlet valve of the IC engine, which affects the fuel mixture quality and combustion of the gas flow during the intake stroke. The charged airflow through inlet valves is fundamentally influenced by the intake port design/opening. The experiment was done to find the Effect of Engine Speed on the Velocity. In this experimental analysis, PIV technique was used to observe the complex flow pattern of the charging gas. The experiments were conducted at various rpm of the engine on a glass single cylinder engine which comprises multi inlet port. It has been concluded that the intake port incredibly changes the inner flow structure. Moreover, at 1320 crank angle the velocity value for 1500rpm reached to 0.6 while for 1000rpm it was 0.33 at full opening valve.
