Niterra lists 4 top trends in automotive ignition technology

Company elects improvement of spark control, reduction of losses in the ignition system, increased energy available in the spark and use of high energy coils

São Paulo, agosto de 2023 – A Niterra, Japanese multinational responsible for the NGK and NTK brands and specialist in components for ignition systems, lists the four main trends in terms of automotive ignition technology in Brazil:

 ;

1: Improved spark control: This advance has happened because of the evolution of systems, starting from the systems with distributor, in which the adjustment depended on the mechanic, moving to more advanced systems and eliminating, so, The use of the distributor. In modern systems, The definition of the moment of firing of the spark began to be determined more precisely during the calibration of the engine - Process carried out by the engineering of the automaker or by the systemist, which is the manufacturer of the injection system;

 ;

2: Reduction of losses in the ignition system: With the elimination of the distributor it was possible not only to minimize the efficiency losses in the system, How to pave the way for more advances. Another step in this evolutionary process has been the adoption of coils directly coupled to spark plugs. With the implementation of these systems, eliminates the need for ignition cables, resulting in a reduction of the natural losses that normally occur due to the use of the cables. Nonetheless, It is worth mentioning that this innovation based on the use of individual coils can result in higher costs at the time of maintenance. This is because the cost of the set of individual coils is, As a rule, much larger than the traditional, with a coil and set of cables;

3: Increased energy available in the spark: the incorporation of spark plugs made of noble metals, as Iridium and Platinum, promotes a significant reduction in the mass of the central electrode of the candle. This optimization not only ensures an easier ignition process due to the tip effect, which facilitates the generation of the spark, as well as decreases energy losses from the flame front to the candle electrode. This results in a higher energy to burn the fuel, minimizing misfires, optimizing the burning of the air/fuel mixture and significantly reducing the extinguisher effect;

4: Use of high energy coils: The energy available in the coils has been increasing significantly, which provides greater energy in the spark, generating a more efficient and complete burning of the air/fuel mixture. The coils represent a major evolution in the concept of these components, since some applications have twice the power when compared to older systems. When associated with the use of noble metal candles then, The gains are significant.

According to Hiromori Mori, Niterra Technical Assistance Consultant, Every evolution of the ignition system aims to help reduce pollutant emissions and improve energy efficiency, playing a decisive role in the achievement of environmental goals by the national automobile industry.

"Niterra contributes to this trend by offering a wide selection of NGK candles made from noble metals, like those of the G-Power series (Platinum) and IX (Iridium), focused on the automotive aftermarket, Tuning and Racing", Mori explains. "They are products that aim to meet the vehicles that have not left the factory with this technology and work as a fast and economical way to improve the performance of the ignition system."

Already the Laser Platinum lines (Platinum) and Laser Iridium (Iridium), factory originals, are ideal for vehicles that adopt these components as an integral part of their initial configuration. beyond the candles, NGK offers a wide range of ignition coils, serving a large part of the national fleet.
