NGK OE on new Volkswagen Golf VII
NGK spark plugs, glow plugs and NTK sensors are being fitted as original equipment (OE) on the new Volkswagen Golf VII.
The contract is the latest in a long line of OE successes for the world’s largest manufacturer of spark plugs and Lambda sensors and second-largest supplier of glow plugs and underscores its role as a strategic supplier to the Volkswagen group of companies.
Tim Ward, Deputy General Manager – Sales & Marketing, NGK Spark Plugs (UK) Ltd, said: “It is tremendous news that our products are to be fitted on such a popular vehicle as the Golf which over the years has enjoyed massive sales in the UK.
“We are continuing to work closely with many of the world’s leading vehicle manufacturers and this agreement is down to the continued hard work and professionalism of NGK’s OE team.”
The 1.2 TSI and the 1.4 TSI petrol engines are fitted with the PZKER7A8EGS spark plug, which is a double platinum type featuring a fine and highly resilient centre electrode with platinum tip and a ground electrode which is directionally orientated to the thread-cut, which improves mixture accessibility and flame dispersion.
In addition, the spark plug’s ground electrode is equipped with a three-layer copper core and also features the ‘Long Insulator’ design introduced in 2011. Its extended insulator prevents flashovers, while the connector’s cup design offers optimal screening of the connection and prevents electrical failure.
For the new EURO 6 diesel engines of the EA288 family (1.6 TDI and 2.0 TDI), Volkswagen chose NGK’s Y1002AS glow plug which has a heater tube with a diameter of only 3.5mm and works with the Advanced Quick Glow System (AQGS), capable of heating up to 1000 °C in less than two seconds.
Additionally, it offers outstanding post-glow abilities. Even at the lowest ambient temperatures it ensures an environmentally friendly cold start and operation until the engine has reached the temperature required for self-ignition.
For the exhaust system, NGK supplies sensors from the NTK brand. The 1.2 TSI model comes with a binary Lambda sensor of the OZAS-S type, which regulates mixture formation, while the 1.4 TSI uses a linear Lambda sensor of the ZFAS-U type as a regulating sensor and the OZAS-S type acts as a diagnostic sensor. Additionally, the ZFAS-U type supports the mixture formation in the 1.6 TDI engine.
Finally, temperature sensors from NTK contribute to optimal operation of the diesel engines, which work with close coupled exhaust treatment. A CTAS-T sensor controls the exhaust temperature upstream of the turbo charger. This ‘Condition Temperature Automotive Sensor – Thermistor’offers a fast sensor light-off as well as exact detection of the exhaust gas temperature within a range from 100 to 900 °C.
