| Abstract: | Aiming at particulate matters sampling and analysis, a full dilute tunnel sampling system for vehicle emission was developed. Its basic integration of full flow dilute and flow control system such as application fields, major technical parameters and Adjustment are introduced with emphasis. As the kernel of flow control system, wide flow range and easy alteration are characteristics of assembled critical flow venturitube. |
