NGK Spark Plug Europe supplies spark plugs with sensor functionality to Lamborghini

At the 82nd International Motor Show in Geneva, Lamborghini showcased the prototype of the Aventador J, a roadster version of the Aventador, which the company launched last year. Both high performers feature spark plugs from NGK Spark Plug Europe with sensor functionality to support the engine’s knocking-detection system.

Lamborghini chose NGK Spark Plug Europe as exclusive supplier of spark plugs for the Aventador, successor of the manufacturer’s famous Murciélago. Both the Aventador and the Aventador J prototype unveiled in Geneva feature an extremely powerful engine: Their hoods conceal a 6.5-litre V12 engine just waiting to take its 700 PS and 690 Nm torque to the street and boost the car to 100 km/h in just 2.9 seconds. However, despite this performance, which is even eight percent higher than that of the Aventador’s predecessor, the car consumes 20 percent less fuel.

A spark plug equally as sophisticated as the engine assists in keeping consumption as low as possible while delivering outstanding performance: NGK’s LMAR9AP8J spark plug was developed especially for the Aventador. It features a two-ground electrode design and a centre electrode with a laser-welded platinum ring. The use of the precious metal ensures that the electrode remains untouched by hot-gas corrosion and spark erosion even under heavy load and extreme temperatures and pressures. Additionally, the spark plug has a long-reaching, 26.5-mm M10 thread with a 14-mm hexagon. Due to this extremely slim design, it leaves more space for coolant ducts within the cylinder head, improving the cooling in this crucial area.

On top of these characteristics, the LMAR9AP8J comes with a secondary ability absolutely vital to the engine: It acts as a sensor for the engine’s knocking-detection. The centre electrode is linked to an independent control unit which measures the ionic current between the electrodes. This current is proportional to the degree of ionisation within the combustion chamber. With the aid of appropriate analysis, this information in turn provides an accurate picture of the combustion quality. Thanks to this system, initial stages of misfiring and detonation can be detected, enabling the engine management system to adjust its settings accordingly.
