Hyundai has patented a new spark plug with two central electrodes, allowing for it to generate two sparks with a single coil - something only achieved in the past by having dual ignition coils and spark plugs.
In essence, the engineers have made use of an unused pocket of output voltage found in the coil's high-voltage side. When inspiration struck, this lead to the addition of a secondary center electrode to the traditional sparkplug design.
By creating two sequential sparks with one plug, it increases the size of the flame front and leads to improved energy conversion efficiency, fewer emissions and better fuel economy - all resulting in better performance from the engine.
Hyundai's engineers have taken it even further with reliable remote monitoring for these plugs so that premature wear is nothing to worry about.
This enhanced efficiency could prove pivotal for Hyundai's N models such as the Elantra N and ensures that combustion engines remain competitive for years to come.
