Motorcycle 4v refers to the number of valves in the engine, where 4v means four valves—two intake valves and two exhaust valves. Introduction to the engine: An engine (Engine) is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. Cylinder arrangement of the engine: Cylinder arrangement, as the name suggests, refers to the arrangement of cylinders in a multi-cylinder internal combustion engine. Simply put, it is the queue form of the cylinders on an engine.

What are the reasons for the ABS light, skid light, and brake light to illuminate?

ABS light can illuminate in various states, with different causes and solutions for each state, as detailed below: State 1: ABS warning light stays on (most common). Cause 1: The ABS speed sensor's sensing part is covered by dirt, mud, or other contaminants, affecting the sensor's ability to detect the corresponding speed signal. This prevents the ABS computer from determining the vehicle speed and the wheel's slip rate, thus failing to issue appropriate commands to adjust braking. Solution: Clean the dirt off the speed sensor and adjust the gap between the speed sensor and the signal ring to restore normal function. Cause 2: Loose connections in the system wiring or poor contact of the ABS relay can cause signal issues, leading to system failure. Solution: Check the wiring connections and reconnect any loose parts. State 2: ABS warning light intermittently illuminates but turns off when accelerating. Cause: When multiple vehicle electrical devices are in use, the battery voltage drops below 10.5V. As the engine speed increases and voltage rises, the ABS light turns off. This can also occur if the ABS system's power supply voltage is too low due to poor terminal contact or grounding issues. Solution: Check the battery's specific gravity; inspect the charging system; examine the power supply (e.g., voltage relay or poor power contact). State 3: ABS warning light stays on after engine start and only turns off when the engine is turned off (IGFF). Cause: Poor grounding contact of the ABS hydraulic valve body; poor contact in the ABS hydraulic valve body's wiring connector; ABS computer failure. Solution: Loosen the grounding screw of the hydraulic valve body, then retighten it, cleaning the contact surface if necessary; check if the connector gap has widened; replace the ABS or ABS/ASR computer. State 4: ABS warning light illuminates during high-speed driving. Cause: At high speeds, the ABS computer detects a significant discrepancy between the rear and front wheel speed signals; incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's tire and wheel rim specifications, as indicated on the sticker near the fuel tank cap. State 5: ABS warning light intermittently illuminates. Cause: Improper adjustment of the brake light switch; poor internal contact in the brake light. Solution: With the engine running, press the brake pedal, push the brake switch linkage down fully with a finger, then release the brake pedal to complete the self-setting position; replace the brake light switch if necessary. If the ABS warning light is on, it is advised not to continue driving. An illuminated ABS light indicates a malfunction in the vehicle's anti-lock braking system. During emergency braking, if the wheels lock up, the vehicle may skid uncontrollably, making it difficult for the driver to slow down or adjust the vehicle's trajectory, posing significant safety risks.

Do White Cars Need Coating?

White cars do need coating. White car paint is not resistant to dirt, and over time, oxidation can cause the paint to turn yellow. Coating can make the car's surface brighter, and even if minor scratches occur, the damage to the car's surface is minimal. Therefore, it is necessary to coat a new white car. The method of coating includes: 1. Using clay bars to remove dirt from the car's paint surface; 2. Applying the coating material evenly on the paint surface with a sponge; 3. After drying, wiping off excess material with a special towel. The composition of the coating agent includes: glass fiber, silicon polymer, fluorine polymer, and high-purity water non-petroleum environmental materials.
