    "device_name": "Plasma Jet Ignition",
    "goal": "Increase ignition spark energy and efficiency to achieve more complete fuel combustion and higher engine performance.",
    "problem_addressed": "Conventional spark ignition is very inefficient (~=0.01% conversion) and often leads to incomplete fuel burning, high emissions, and limited power output.",
    "concept_summary": "The invention adds a one-way current path between the primary and secondary windings of the high-voltage ignition transformer. After the initial spark, energy stored in the capacitor flows through this path across the spark-plug gap, producing a high-current plasma arc that ionizes the surrounding air, creating a bright white plasma ball and a more energetic ignition event without requiring a separate power supply.",
