The "hot ily stores the charge from the coil and increases the current value, which greatly shortens the discharge time and generates a powerful spark that discharges at once. This powerful spark with exnt ignition properties forms a huge flame nucleus, which reliably burns the air-fuel mixture instantaneously, achieving a state closer to complete combustion. The original power and torque of the engine, which was previously lost due to incomplete combustion of the air-fuel mixture, is revived, and the condition of the engine is greatly improved.
