What are the characteristics of a dual-spark plug gasoline engine?

[DeCatherine]

The characteristic of a dual-spark plug gasoline engine is that the ignition capability of the engine with dual spark plugs is relatively strong, allowing for more complete combustion of gasoline. The intelligent dual-spark plug sequential ignition i-DSI system changes the conventional ignition method of one spark plug per cylinder to installing two spark plugs on one cylinder, positioned on the intake side and the exhaust side respectively. This shortens the flame propagation time within the combustion chamber, achieving rapid combustion across the entire range. How spark plugs work: The spark plug's ground electrode is connected to the metal shell, which is threaded into the engine block via the cylinder head. The insulator primarily serves to isolate the metal shell from the central electrode. The terminal nut is the part of the spark plug that contacts the high-voltage coil. When current passes through the terminal nut and the central electrode, it breaks down the medium between the central electrode and the ground electrode, generating a spark to ignite the air-fuel mixture in the cylinder.
