Block ignition coils
A block ignition coil contains multiple ignition coils that supply the spark plugs with the necessary high-voltage pulse through their respective individual high-voltage outputs and via ignition cables.
ignition coil rail (ignition module)
This design is used by some vehicle manufacturers. It combines several single-spark and dual-spark ignition coils into one unit, also known as a rail. It is mounted on several spark plugs simultaneously. One benefit: such systems can be equipped with a flow gauge, which can be used to monitor the combustion quality in the engine control unit. Depending on number of cylinders – are arrayed in a common housing (rail). However, these coils are functionally independent and operate like single spark ignition coils. The design advantage is fewer connecting cables are required. One compact plug connection is sufficient.
