Why do spark plugs only fire once per ignition cycle?
Why do spark plugs only fire once per ignition cycle?
Spark plugs with more than one ground electrode do not generate multiple sparks because the plug only fires once per ignition cycle. The multiple electrodes merely provide multiple surfaces the spark can jump across to reduce the wear on any given electrode.
What happens if there is no spark in the ignition?
