What causes spark plug leakage in Haval H6?

[ValerieAnn]

Haval H6 spark plug leakage may be caused by improper installation of the spark plug or faulty ignition cables. Relevant information about spark plugs is as follows: 1. Introduction: The spark plug is a crucial component of the gasoline engine 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. 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. Working Principle: Under high voltage, the air between the spark plug's center electrode and side electrode rapidly ionizes, forming positively charged ions and negatively charged free electrons. When the voltage between the electrodes reaches a certain level, the number of ions and electrons in the gas increases like an avalanche, causing the air to lose its insulating properties.
