| Abstract: | The authors make research on structural parameters of combustion chamber and exhaust tube (C.E.T.) of pulse-jet fogger. The principle of pulse combustion and the theory of non-steady, one-dimensional of compressible flow are used to analyse and verify their selection. The results has shown that the pulse-jet engine operates under the acoustic resonance. The self-excited vibration system consists of a(C.E.T.) unit, one-way air-inlet valve and one-way fuel valve. The structural l parameters of C. E. T. has a great effect on engine performance. |
