What are the types of automotive spark plugs?

Automotive spark plugs can be categorized into the following types: 1. Standard Spark Plug: Its insulator skirt is slightly recessed into the shell end face, with the side electrode located outside the shell end face. It is a widely used type. 2. Extended Insulator Spark Plug: The insulator skirt is longer and protrudes beyond the shell end face, offering advantages such as greater heat absorption, better anti-fouling capability, and direct cooling by incoming air to reduce temperature. 3. Fine-Wire Spark Plug: Its electrode is very thin, characterized by strong sparks and excellent ignition performance, ensuring quick and reliable engine starts even in extremely cold conditions. It has a wide heat range, suitable for various applications. 4. Tapered Seat Spark Plug: The shell and threaded portion are conical, eliminating the need for a washer to maintain a good seal, thus reducing the spark plug size, which is more beneficial for engine design.

How to Repair Scratched Rims?

Methods for repairing scratched rims: 1. Use sandpaper to sand the scratched area of the rim, removing all scratches; 2. After removing the scratches, apply body filler to level the surface, then continue sanding; 3. Once the rim surface is smooth as new, proceed with painting; 4. After painting, take the rim to a specialized workshop for baking to ensure quick drying; 5. Once dried, the entire rim is considered fully repaired. Aluminum alloy wheels are generally manufactured through casting or forging processes, both of which produce wheels with high hardness. During daily use, severe scratches or collisions may not compromise the wheel's performance but will leave marks on the surface. Therefore, it's essential to pay extra attention in daily use.

How to Adjust a Car Clutch?

Methods for adjusting a car clutch: The clutch can be adjusted by adjusting the nut. The free travel of the clutch pedal is allowed to be 15 to 25mm, and the total travel is 150mm. Pay attention to the installation position of the release shaft rotating arm. Tightening the screw of the cable clutch raises it, while loosening it slightly lowers it. The hydraulic clutch control part is not adjustable. The mechanical clutch can be adjusted by adjusting the tightness of the clutch cable or by changing the length of the clutch cable. The former method allows for fine-tuning, while the latter has a larger adjustment range, which falls into the category of modification. Poor adjustment can affect driving safety.
