When setting the ignition timing on a coil- on- plug ignition system, the technician must first None of these.
If the ignition time is set too advanced then the charge gets combusted during the contraction stroke, resulting in the peak pressure achieved inside the engine during the compression stroke. This peak pressure resists the movement of the piston toward TDC. Thus it results in a loss of power and chances of knocking.
Coil-on-plug assemblies are developed to convert a low voltage (primary side) to a high voltage (secondary side) to fire the spark plugs. They perform the roles of both the ignition coil, which creates the spark energy and the spark plug wire set, which produces the high voltage energy to the spark plug.
