The exhaust sampling system using California Analytical Instruments analyzers was re-designed to provide increased functionality, reduced down time, and reduced maintenance costs. The project phases consist of concept formulation, initial design formulation, detailed design, and final assembly. The performance of the sampling system is verified by conducting a dynamometer test using a diesel engine as an exhaust source. Data was acquired to eliminate any unforeseeable issues that may have arisen from the design and fabrication process. Simple design changes were made after the first trial and those changes were validated through the second test trial. It was concluded that a functional sampling system can be designed and constructed in-house. It was also demonstrated that the thermoelectric sample gas chillers used in the design of the sampling system are capable in delivering a consistently dry sample provided the sample pressure and ambient temperature are kept stable.
