What material spark plug is used in the Volkswagen Lavida?
1 Answers
The Volkswagen Lavida uses nickel-plated copper spark plugs. Spark plugs, commonly known as fire nozzles, function by discharging the pulsed high-voltage electricity delivered by the high-voltage wire, breaking down the air between the two electrodes of the spark plug to generate an electric spark, thereby igniting the air-fuel mixture in the cylinder. Location of the spark plug: Spark plugs are installed on the side or top of the engine. In early designs, spark plugs were connected to the distributor via ignition wires. Over the past decade, most car engines have been updated to connect the ignition coil directly to the spark plug. Working principle of the spark plug: The ground electrode of the spark plug 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. Effects of spark plug damage: If the spark plug is damaged, it can directly cause issues such as leakage in the vehicle's ignition system, increased fuel consumption, and reduced power. The most significant problem is difficulty in ignition, affecting the normal operation of the vehicle. Severe erosion of the spark plug, such as scarring at the top, damage, or melting and erosion of the electrodes, indicates that the spark plug is damaged and should be replaced.
