Abstract

Noise generated in the operation of an internal combustion engine is an energy waste that produces noise pollution. Recovering some of this energy and transforming it into another form of usable energy brings significant benefits. We proposed to develop a device to recover this energy waste produced by the internal combustion engines, in the gases changing process. The developed energy recovery system is based on the Helmholtz resonator principle. For the conversion of acoustic waves into electricity, we used an audio speaker as a low-cost electromagnetic transducer located at the end of the resonant chamber. By audio playback of the acoustic signal recorded at the engine exhaust, we measured the electricity generated with the proposed recovery system. We found that the noise level measured at the exhaust depending on the engine speed range, follows a linear distribution law, instead, the harvested electric power varies nonlinearly. To find out the cause of the electric power variation, we performed a detailed FFT analysis. We found that at most engine speeds, the dominant amplitudes in the frequency spectrum are close to the resonant frequency of the system. With the proposed conversion system, we obtained a maximum value of the harvested electric power of 165 µW.
