• In the paper, the reflective conditions of pressure wave in some exhaust pipe systems were measured by the shock-tube method. This method was based on the characteristic relation of pressure wave and the shocktube principle. The results obtained were as follows : (1) As to nozzle, the experimental results showed coincidence with the theory for a weak shock wave, but as the strength of its incident pressure increased, the discharge coefficient became larger. (2) Judging from the theory and the experimental results, the diffuser effect could not be improved for the area ratio above 4. (3) As to bends or elbows, the experimental results agreed well with the theory. (4) These results were able to clearly explain the phenomena in the last experiments obtained by using a uniflow two cycle diesel engine.
