Abstract： Aiming at the problem of low ignition energy of traditional spark plugs， this paper proposes an ignition enhancer design scheme based on capacitor energy storage. Through the combination of PSIM simulation and experimental verification， a composite circuit structure including a storage capacitor and an isolation diode was designed and constructed. The research results show that every 100 V increase in the charging voltage of the booster increases the discharge current of the ignition plug by 20%～25%; when the equivalent resistance value of the spark plug is 10 Ω and the initial voltage of the booster capacitor is 1 000 V， the maximum output current reaches 100 A， which is nearly two orders of magnitude higher than the original igniter. On the built experimental test device， the output characteristics can be effectively controlled by adjusting the charging voltage （500～800 V） and charging current （10～50 mA）. The ignition energy of the spark plug connected to the booster is 5～10 times higher than that of the non-booster. The enhancer proposed in this paper is expected to provide support for the high-energy ignition needs of ammonia-fueled engines， and is of great significance for improving engine combustion efficiency and reducing emissions.
