A new type of thermoacoustic sound wave generator driven with the waste heat of a 4-cycle automobile gasoline engine is described. The exhaust-pipe-connected sound wave generator, in which the hot heat exchanger is set in the exhaust pipe in order to recover the waste heat of exhaust gas, is proposed. A temperature of 780℃ of exhaust gas in the exhaust is observed. In a conventional thermoacoustic sound wave generator, sound waves originate at a temperature of the hot heat exchanger, T_H, of 200〜300℃ and become sufficient at 700℃. It is confirmed that the new generator generates sufficient sound waves and its performance is almost equal to that of the electric-heater-driven generator at a thermal input of 300W, which corresponds to slightly more than 1% of the heat quantity of exhaust gas provided under the condition that the number of engine revolutions is 2600 r.p.m. and that the throttle opening is 35%.
