What Causes Sudden Loss of Power in a Car?

[Curtis]

Common causes of insufficient vehicle power include: a dirty or malfunctioning engine throttle. The throttle's function is to regulate the amount of air entering the engine; if the throttle valve plate is excessively dirty, it can lead to imprecise opening of the valve plate. The role of the spark plug is to generate an electric spark in the engine combustion chamber to ignite the air-fuel mixture. Relevant information about spark plugs is as follows: 1. Introduction: The spark plug is a critical component of the gasoline engine ignition system. It introduces high voltage into the combustion chamber, causing it to jump the electrode gap and produce a spark, thereby igniting the combustible 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.
