IGNITION COILS

With a distributor ignition coil, the ignition coil generates a high-voltage pulse. This pulse passes through an ignition cable to a mechanical ignition distributor. After that, the high-voltage pulse is distributed to the corresponding ignition cable, which provides voltage to the cylinder. Older vehicles use this type of ignition coil; it was in use well into the 1990s.

A block ignition coil contains multiple ignition coils. These supply the spark plugs with the necessary high-voltage pulse through their respective individual high-voltage outputs and via ignition cables. Block ignition coils use single and dual spark technology.

Pencil coils require no ignition cables; they are attached directly to the spark plug. As a result, the coil generates the high-voltage pulse directly at the spark plug. The advantage: there is essentially no voltage loss through the cable. In addition, this compact design leads to valuable additional space. This is particularly important in modern engines.

This ignition coil type comprises multiple ignition coils, which are combined to form a single, compact component. All ignition components are connected to the spark plugs in one step. This type also includes so-called “rails”.

Ignition coils provide the spark plug with the high voltage required to generate a spark. The ignition coil is an induction coil that transforms the battery's low voltage to the high voltage that is needed to create an electric spark in the plugs and ignite the petrol. NGK ignition coils are accurately engineered for a precise fit (correct seating), high vibration resilience, effective short-circuit and moisture resistance, and long-lasting durability.

Symptoms of a bad or failing ignition coil include engine misfiring, rough idle, a reduction in power and even a complete failure to start the vehicle. In such cases, the ‘check engine light’ on the dashboard will be activated.
 

Niterra offers six different types of ignition coils. These are: Distributor Coils, Block Coils, Block Coils with two high voltage outputs, Pencil Coils with double spark and single spark technology and Coil Systems (also known as ‘rails’).
