What is the spark plug model for the Vios?
1 Answers
The spark plug brand for the Vios is DENSO from Japan, with the model number C16HR-U11 and a heat range of 5. It is a high-end product from DENSO. The spark plug is a crucial component of the gasoline engine's ignition system. It introduces high voltage into the combustion chamber and generates a spark by jumping across the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. 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 center 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 center electrode, it ionizes the medium between the center electrode and the ground electrode, producing a spark that ignites the air-fuel mixture in the cylinder. Spark plug replacement interval: Under normal maintenance conditions, replacement is recommended every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it's advisable to follow the owner's manual. The following standards can be referenced for maintenance and replacement: Platinum spark plugs should be replaced at 40,000 kilometers, standard nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers.
