When selecting spark plugs for motor vehicles, it is important to consider the specific requirements of the vehicle, including heat range, electrode design, and material composition. Iridium spark plugs are known for their fine-wire electrode and superior durability, making them suitable for a wide range of motor vehicle applications. The use of high-quality iridium spark plugs can contribute to optimized engine performance, fuel efficiency, and emissions control, ensuring reliable operation and reduced environmental impact.

When the engine is running, the ignition coil receives a signal from the engine control unit to fire at the correct time. The coil then rapidly builds up a magnetic field within the primary winding when the signal is received, and when the signal is cut off, the magnetic field collapses rapidly, inducing a high voltage in the secondary winding. This high voltage is then sent to the spark plug, where it jumps the electrode gap, igniting the air-fuel mixture in the combustion chamber.

Bauerle and Bruhnke⁷ found that aeration reduces the effect of oil additives on fluoroelastomer properties. Some of their data is reproduced in Fig. 14.4,⁵ showing the effect of aeration of an SF-grade 5W30 oil on the retention of elongation of a VDF/HFP copolymer (FKM-E430), a VDF/HFP/TFE terpolymer (FKM-B600), and a VDF/PMVE/TFE fluoroelastomer (FKM-GFLT). The HFP-containing polymers show much better retention of properties with aeration.

New spark plugs are integral to the efficient operation of the engine, playing a critical role in igniting the air-fuel mixture within the combustion chambers. Over time, spark plugs can become worn or fouled, leading to decreased engine performance, rough idling, and reduced fuel efficiency. Replacing old spark plugs with new ones is essential for maintaining optimal engine performance, fuel economy, and emissions control. High-quality new spark plugs contribute to reliable ignition, smooth engine operation, and reduced environmental impact.

of the component due to extreme temperatures, causing premature deterioration of the oil seal material.

FKM or FPM, which is in well-known brand Viton™, can withstand higher liquid temperatures of up to 180 ˚C. FKM is highly resistant to strong acids and bases, as well as to synthetic oils and greases. Glycol-based oil and grease, however, can also damage FKM.

Finding oil spots under a parked vehicle can be both worrying and stressful for any vehicle owner. If the seal’s leak is small, oil may start to accumulate on the underside of the engine. But as the leak gets bigger, the oil leak will become visible in the front side of the engine.
