| Abstract | This study aims to investigate the impact of high-voltage ignition coils on engine combustion efficiency. During the experimental process, corresponding experimental equipment and components were selected and used to compare and analyze the performance of standard and modified high-voltage ignition coils. Detailed comparisons were made on the resistance, inductance values, peak voltage, and specifications of spark duration, voltage rise, and voltage storage time of the high-voltage ignition coils. During the experiment, an oscilloscope was used to sample multiple waveforms of the high-voltage ignition coil, and the data collected by the oscilloscope was used for a deeper understanding and evaluation of the performance of the high-voltage ignition coil. Taking into account factors such as resistance and inductance values, the thermal exhaustion phenomena of the high-voltage ignition coil under different temperatures were deeply discussed. Waveform data sampled by the oscilloscope was converted into Duty Cycle and plotted as a curve for analysis. Through the curve graph, the causes of differences under the thermal exhaustion conditions of different high-voltage ignition coils were investigated, and the effects on thermal exhaustion and curve graph results were analyzed. In the later stage of the research, an engine dynamometer was used for experiments, respectively outputting horsepower, torque, rotational speed, and air-fuel ratio curve graphs for cross-comparison analysis. Through comparing the performance of standard and modified engines, combustion efficiency analysis was carried out to evaluate the impact of the modified high-voltage ignition coil on engine performance. After detailed research and experimental analysis, we have reached a clear conclusion: Modifying the high-pressure ignition coil significantly improves the engine's combustion efficiency. This will have a significant positive impact on engine performance. |
