Master thesis deals with design of the exhaust system for measuring stand consisting of an internal combustion engine which releases flue gas, a sampling system, a filter, a blower, a heat exchanger, a silencer and a safety system. The introduction describes the origin of the exhaust system, it’s problems and the purpose of the universal exhaust system. The theoretical part describes about the IC engine, it’s process and mechanism. It also has description about the emission of exhaust gases. The specification of the engine to be used is also described. The second half of the thesis is mainly focused on the design of the universal exhaust system and also the sampling system. The calculation for the pipe diameter and the design of the heat ex...
