Innovative application of low-frequency resonance technology to cars for fuel-saving and emission-reduction: Case studies

Transportation sector is facing the issues of reducing air pollutants emission and fuel-consumption from the viewpoint of environmental protection and energy-saving. A newly developed low-frequency resonator (LFR) that contained low-frequency resonated-liquid was installed at vehicles to test its capability of reducing emissions and increasing driving ranges. For emission reduction performance, a car was tested for 1038 days, including a 2.5 year-long third-party field inspection. For energy-saving performance (shown as driving range increments), 30 cars with three car manufacturing companies of Toyota, Mitsubishi and Ford were tested. The emission and mileage values were compared before and after the LFR installations to these cars. The field test results were (1) hydrocarbon and carbon monoxide emission reductions reaching 62–88% and (2) driving range increments reaching 11.8–37.2% with an average value of 19.8%, indicating an innovative and effective application of low frequency resonance technology to cars in air pollutant reduction and fuel-saving. Moreover, some future work has been suggested to confirm the effectiveness of the LFR device.
