NGK explains the differences between the types of ignition coils

A empresa ainda destaca os perigos e os malefícios de fazer alterações não projetadas nesses componentes

São Paulo, setembro de 2024- The main purpose of a coil in a vehicle's ignition system is to transform the system's voltage into high voltage, que pode atingir até 45.000 volts, with the coils being classified according to the drive and the shape. Installing an improper or poor quality coil can result in increased fuel consumption, difficulty starting the engine, malfunctions and even damage to the vehicle's electrical and electronic system. To avoid these problems, and NGK, Niterra brand specialized in components for ignition systems, provides information to help you choose the right coils for your vehicles.

1- Coils with ignition module attached: The injection module sends an electronic signal to the coil, and the coil module drives the charging circuit.

2- Coils without ignition module attached: Charging is carried out directly by the injection module.

3- Individually shaped coils: Each cylinder has its own coil, which can be attached directly to the spark plug or connected by a cable.

4- Block coils: They can contain one or more coils in the same body, being single or double, When doubles, have two outlets to power two twin cylinders, Those who always rise together, but in different phases, one in compression phase and one in exhaust phase.

"The coils are designed with each motor's unique specifications in mind and undergo rigorous engineering testing. That is why, It is recommended to avoid adaptations", explains Hiromori Mori, Niterra Technical Assistance Consultant. "By opting for a new ignition coil, We must consider the technical requirements and design characteristics. Modifications or adaptations without a detailed understanding can cause problems, such as decreasing the durability of the coil, increase in fuel consumption and damage to other components."

Maintenance for Ignition Coil Longevity

With the growing demand for reduced pollutant emissions, Ignition systems have evolved significantly, highlighting the use of noble metal candles, such as iridium and platinum, plus single coils per cylinder and high-energy coils, that promote more efficient fuel burning. Even with these advances, proper maintenance of ignition system components, especially spark plugs, is essential to ensure its longevity. Worn spark plugs require greater tension to generate the spark, increasing stress on the coils and reducing their service life.

In the replacement of these parts, NGK offers an e-catalog and a mobile app, making it easier to identify the correct application of ignition coils. Consumers can check the website to find the coil that suits their vehicle.
