Another common cause of black spark plugs is engine oil leakage. If oil is leaking into the combustion chamber, it can cause the spark plugs to become fouled with a black, sooty residue. This can lead to misfires and engine hesitation, as well as increased fuel consumption. It is important to address any oil leaks promptly and replace the spark plugs if necessary.

• ERIKS type R (type A according to the DIN standard) is identical in shape to type M, but has a rubber outer case with metal reinforcement on the inside. The rubber creates a good seal in the housing, even if the housing has suffered minor damage or is not in its best condition for other reasons. The RST version has a dust lip. These types are often chosen to replace a type with a metal outer case because they are easier to install and can cope with minor damage to the groove, such as scratches.

• The MK7 GTI's spark plugs also contribute to the vehicle's emissions controlmk7 gti spark plugs. By ensuring a clean and complete burn of the fuel, they minimize unburned hydrocarbons, contributing to reduced pollution. Moreover, their precision engineering helps prevent misfires, which could otherwise lead to engine damage.

• In addition to their functional capabilities, oil seals also play a crucial role in extending the life of machinery. By preventing the loss of oil, seals help maintain the proper lubrication of the moving parts, reducing wear and tear and extending the interval between maintenance. This not only saves time and money but also helps to minimize downtime and increase productivity.

• In different applications like tyres, belts, and oil seals, situations where resistance to fatigue with improved life span is desired, and in gaskets, and electronic and electrical equipment, conventional type rubbers are reinforced with filler materials to enhance their physical, electrical, thermal, and mechanical properties. Compared to the conventional rubber/rubber composite-reinforced fillers, the addition of nanomaterials has gained extra attention in recent years, and these are called nanocomposites [40,61]. Nanomaterials have unique properties which are changed due to their size reduction in any one dimension, like chemical (reactivity or catalysis), thermal (melting temperature), electronic (electrical conductivity), optical (scattering or absorption of light), or magnetic (magnetization) properties [40]. Among various types of nanomaterials, CNTs are one of the most attractive reinforcements used in the rubber nanocomposites, due to their high aspect ratio, flexibility, diameter in the nano range, and physical, mechanical, and electrical properties along the axis of the tube. MWCNTs have greater advantages than SWCNTs or DWCNTs in the range of possible industrial applications and low production cost, which can also provide similar composite properties [40,62,63]. In nanocomposites, uniform dispersion of the CNTs plays a very important role in increasing the properties of the developed material. This is because of the bonding between the nanotubes being very high and ending up in a cluster formation [63]. In recent research, MWCNTs/SWCNTs were used as reinforcements and mixed with caoutchouc or natural rubber matrix material to obtain an MWCNT/SWCNT–natural rubber nanocomposite (nanostructures), by adding the CNTs into a polymer solution like acetone, dimethyl formamide, toluene, or tetrahydrofuran and mixing either by high-energy sonication, magnetic agitation, or mechanical mixing. Simultaneously, in addition to the poor solution, the solvent gets evaporated and obtains better dispersion of nanotubes. It is a better method to achieve uniform dispersion and distribution of nanotubes into the matrix material. One major constraint for this method is neglecting the improper solubility of polymer into the solvent to carry out the next process [40]. Also, MWCNTs improved the mechanical and electrical properties of other types of rubbers, such as chloroprene, acrylonitrile–butadiene, styrene butadiene rubber, and ethylene–propylene–diene monomer [62].

• Despite its simple appearance, the U-shaped silicone gasket's impact on efficiency, safety, and cost-effectiveness cannot be understated. It is a silent workhorse, quietly ensuring that machinery runs smoothly, pipelines remain leak-free, and electrical systems operate safely.

• One of the key benefits of spark plug sets is their ability to improve fuel efficiency. By ensuring that each spark plug fires consistently and efficiently, these systems help reduce the amount of fuel required to power the engine.
