If a 2.0 liter 4 cylinder four stroke engine idles at 800rpm, how many times a minute does each of the 4 spark plugs fire?
Does the number of spark plugs affect the engine's performance?
Yes, the number of spark plugs can affect the engine's performance. More spark plugs can provide better ignition and combustion, resulting in better performance and fuel efficiency. However, adding too many spark plugs may not always improve performance and can even harm the engine.
