Where is the spark plug, car spark plug location map

The spark plug position is generally inside the engine cylinder, which can be clearly seen after removing the high-voltage ignition coil. The specific car spark plug position diagram is shown below.

Spark plugs use high-voltage discharge to break down the air between the electrodes to generate electric sparks to ignite the combustible mixture in the gas chamber to maintain engine operation. The main types of spark plugs are: standard spark plugs, protruding edge spark plugs, electrode spark plugs, seat spark plugs, polar spark plugs and so on.

Because every time the engine runs, it needs a spark plug to do work. Therefore, the quality of the spark plug directly affects the performance of the automobile engine. Among all the spark plugs, the precious metal spark plug has the best performance. Among them, iridium spark plugs are more than twice as long as normal spark plugs, and because the ignition speed of iridium spark plugs is extremely fast, the acceleration performance of iridium spark plugs is also the best of all spark plugs.

Spark plugs also need regular maintenance. If the speed of the car is 1,000 revolutions, then the spark plug needs to do 500 times per minute. It can be said to be the busiest part of the car. It must be maintained with gasoline or kerosene and other liquids. After the carbon deposit is softened, clean it with a non-metallic brush, and then dry it with compressed air. Remember not to use a knife to scrape, otherwise it is very likely to damage the electrode.
