petrol station pressure washer
One of the most appealing features of electric high-pressure car washers is their user-friendly operation. Most models are lightweight and portable, allowing car owners to wash their vehicles conveniently at home, without the need to visit a car wash. Additionally, many units come equipped with adjustable nozzles that allow users to switch between different spray patterns, depending on the type of cleaning required. For instance, a wide spray may be ideal for rinsing off soap, while a concentrated jet could effectively blast away stubborn mud or tar.

porcelain spark plug. The ceramic material used in porcelain spark plugs provides excellent insulation, preventing the electrical current from leaking out and ensuring a consistent spark every time.
Operating temperatures for engine oil seals (see Fig. 14.11 and cross-section of lip seal with garter spring in Fig. 14.22) vary widely, depending on engine design and location within the engine. Typically, the rear crankshaft seal is subjected to much higher temperatures than the front seal. Oil sump temperatures vary considerably, depending on provisions for oil cooling. This allows use of hydrogenated nitrile (HNBR), silicone, or acrylic elastomers for some seals in relatively low-temperature environments (120–140°C or 250–284°F). Standard fluoroelastomers (FKM), bisphenol-cured VDF/HFP/TFE terpolymers with 68–69% fluorine content, perform well in oil service up to about 160°C (320°F). More resistant fluoroelastomers are necessary for reliable long-term performance in more severe environments.
