How often should the spark plugs be replaced on a Mercedes-Benz C260L?
1 Answers
Mercedes-Benz C260L spark plugs should be replaced every 20,000 kilometers. Here are the detailed specifications: 1. Overview: The spark plug is a crucial component of a gasoline engine's ignition system. It introduces high-voltage electricity into the combustion chamber, creating a spark across the electrode gap to ignite the air-fuel mixture in the cylinder. It mainly consists of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell, with the side electrode welded to the shell. 2. Structure: Steel Shell: The lower part of the steel shell has fine threads for installation into the cylinder head's spark plug hole, while the upper part features a hexagonal nut for use with a spark plug socket to tighten or remove the spark plug. The metal rod serves as the center electrode. The lower end of the metal rod contacts the upper end of the center electrode via conductive glass, and the upper end of the metal rod is equipped with a terminal nut. High-alumina ceramic insulation is placed between the steel shell and the center electrode to ensure electrical insulation when powered. The bottom of the steel shell has a curved side electrode, and the middle of the shell's exterior includes a copper gasket.
