What is a Headlight Lens?

A headlight lens is an optical glass lens assembly installed in front of the headlight bulb, which helps focus the light beam more effectively, extending its range and thereby achieving better illumination. Below are specific details about installing lenses: 1. Lens Selection: As long as the lens does not impair the headlight's lighting capability, it generally passes annual vehicle inspections. High-end vehicle models often come equipped with lenses, in which case no registration is required. Installing a suitable lens can address the issue of scattered light from the original headlights, significantly enhancing nighttime driving safety. 2. Penalty Information: According to Article 90 of the Road Traffic Safety Law, unauthorized installation of lenses or xenon headlights, considered as illegal vehicle modifications that compromise safety, is punishable by a 3-point penalty.

What does a vacuum-assisted braking system mean?

Introduction to the meaning of vacuum-assisted braking system: Gasoline engines can generate high vacuum pressure in the intake manifold, while diesel engines and direct-injection gasoline engines require the installation of a vacuum pump to provide the vacuum source, meeting the requirements of the vacuum-assisted braking system. Below is an introduction to the principle of the vacuum-assisted braking system: 1. The brake booster utilizes the principle of the engine drawing in air during operation to create a vacuum on one side of the booster, generating a pressure difference compared to the normal air pressure on the other side. This pressure difference is used to enhance the braking thrust. 2. Even if there is only a small pressure difference on both sides of the diaphragm, due to the large surface area of the diaphragm, it can still generate a significant thrust to push the diaphragm toward the side with lower pressure.

How many cubic meters can a 6.8-meter high-barrier truck carry?

6.8-meter high-barrier truck can carry 30~40 cubic meters, depending on the type of cargo. Below is a detailed introduction to the 6.8-meter truck: Overview: The 6.8-meter truck compartment is also called a 5-ton truck or 4.5-ton truck, referring to freight vehicles with a compartment length of 6.8 meters. Due to different transportation needs, the compartment dimensions, volume, and load capacity of 6.8-meter trucks or 5-ton trucks may vary. Purpose: The 6.8-meter truck is mainly used for fully sealed transportation of various goods, and special types of van trucks can also transport hazardous chemicals. It offers advantages such as flexibility, ease of operation, high efficiency, large transport capacity, full utilization of space, safety, and reliability.

What is the working principle of a 4-wire brake switch?

A 4-wire brake switch essentially consists of two brake switches—one normally open and one normally closed. When the brake is pressed, the normally open switch closes, and the normally closed switch opens. Each of the four wires serves a different purpose: one is a 12-volt power supply, one is the brake signal wire for the ABS system ECU, one is the brake signal wire for the automatic transmission ECU, and one connects to the rear brake indicator light. 2-wire brake switch: A 2-wire brake switch operates on a break-and-make principle—when the brake is pressed, the switch closes; when the brake is not pressed, the switch remains open. 4-wire brake switch: The two wires on the side of the brake light switch control the brake lights, while the middle two wires provide the brake signal to the vehicle's computer (ECU). Based on this signal and other conditions, the ECU stops fuel supply to the engine, achieving fuel-saving effects.

How many cubic meters can a 4.2-meter high-barrier truck carry?

4.2-meter high-barrier trucks are normally limited to 5 tons, and when fully loaded, they can carry approximately 13 cubic meters. The actual capacity depends on the type of cargo being transported, as the density of each type of cargo varies. For palletized goods, the height of the pallet must be deducted, so the loading volume also differs. Additional information: Generally, a 4.2-meter truck has a length of 4.2 meters, a width of 1.6~1.8 meters, and a height of 1.6~1.8 meters. The height from the ground must not exceed 4 meters, and for vehicles carrying containers, it must not exceed 4.2 meters. Therefore, the typical loading height is only about 2.5 meters.
