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?
I have a question about engines. 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?
To answer your question, each spark plug in a 4 cylinder engine fires once every 2 engine revolutions. Since there are 4 cylinders firing in sequence, each of the 4 spark plugs fires once every 4 engine revolutions.
