Abstract

This study demonstrates a novel energy converter harnessing spring resilience with mechanical vibrations for electricity generation. To investigate the impact of nonlinear vibrations on fuel injection and mixture formation in a spark-ignition combustion chamber. This study develops a multidimensional coupled model that integrates spring dynamics, fuel-air mixing, vibrations, and electromagnetic loading, solved through iterative algorithms, to quantify nonlinear dynamics' effects on fuel injection and mixture formation in combustion alternators. The results indicate that variations in spring stiffness affect vibration of the vibration combustion alternator, altering the compression ratio and the initial conditions for fuel injection and mixture formation. Specifically, under a spring stiffness of 48 kN/m, the equivalent speed of vibration combustion alternator is 1562 rpm, with a compression ratio of 8.0, a fuel evaporation rate of 94.06 %, and a mixing uniformity index of 87.80 %. When the spring stiffness increases to 56 kN/m, the corresponding values are 1714 rpm, 9.1, 79.02 %, and 77.48 %. Higher spring stiffness increases turbulent kinetic energy but does not enhance mixing quality. Targeted spring stiffness adjustment strikes the balance between enhanced injection precision and maintained mixing stability in resonant combustion actuators.
