Functions and Roles of Automotive Wiring Harnesses

Automotive wiring harnesses are components formed by bundling wires to connect circuits. The following are the functions and roles of automotive wiring harnesses: 1. Automotive wires, also known as low-voltage wires, are different from ordinary household wires. Ordinary household wires are single-core copper wires with a certain degree of hardness, while automotive wires are multi-core flexible copper wires. Some of these flexible wires are as thin as hair, with several or even dozens of soft copper wires wrapped in plastic insulating tubes (polyvinyl chloride), making them flexible and not easily broken. 2. With the increase in automotive functions and the widespread application of electronic control technology, there are more and more electrical components and wires, making wiring harnesses thicker and heavier. Therefore, advanced vehicles have introduced CAN bus configurations, adopting multiplex transmission systems. Compared to traditional wiring harnesses, multiplex transmission devices significantly reduce the number of wires and connectors, making wiring simpler.

What is the method for repairing minor scratches on a car body?

Remove the wax film layer, oil film, and other foreign substances from the surface of the paint, clean the scratched area with a wax-removing cleaner, and then let it dry. Use appropriate sanding materials to sand the scratched surface layer. Apply a polishing compound soaked with water, keep the polishing pad surface parallel to the paint surface to be polished, start the polisher, and stop the polishing process when about 95% of the scratches are removed. For any remaining fine scratches or swirl marks left from the sanding and polishing process, perform paint surface restoration. After paint surface restoration, apply wax treatment and repeatedly wipe until the paint film is smooth and shiny.

What is the range of the Volkswagen Lavida pure electric vehicle?

Electric vehicles generally have an average range of over 500 kilometers. The following are the advantages of electric vehicles and factors affecting their range: Advantages of electric vehicles: Pure electric vehicles use electric energy and emit no exhaust gases during operation, thus not polluting the environment. Electric vehicles have higher energy utilization efficiency compared to gasoline-powered vehicles. Factors affecting range: Battery high and low temperature technology, optimization of battery BMS technology, upgrades to the vehicle's energy recovery system, lightweight body design, energy-saving technologies for hardware equipment, etc. Additionally, external driving conditions, air resistance coefficient, mechanical transmission efficiency, vehicle weight, number of passengers, and other factors will affect the actual range of an electric vehicle.

What are the consequences of a car running out of water?

If the water tank runs out of water or has insufficient water, the temperature inside the cylinders will rise rapidly. If the excessive heat is not dissipated in time and high-load driving continues, the strength of components such as pistons, piston rings, and connecting rods will decrease, or even deform, making them unable to withstand normal loads. Below is relevant information: 1. Function: The cooling water in the car circulates to work. The role of the cooling water in the car is to cool the engine block. The car engine must be properly cooled under high-temperature working conditions to maintain it at a suitable operating temperature, ensuring good engine performance, durability, and exhaust emission requirements. 2. Consequences: The inability to maintain a normal oil film between parts will inevitably lead to engine damage due to overheating, ranging from cylinder and bearing wear to severe engine failure and scrapping.

Are Car Faux Leather Seats Durable?

Faux leather materials also vary in quality. High-end automotive faux leather offers advantages such as abrasion resistance, cold resistance, breathability, aging resistance, soft texture, environmental friendliness, and an attractive appearance. Therefore, high-end faux leather seats can last for 8 to 10 years without issues. Below are the pros and cons of faux leather seats: 1. Pros: Faux leather seats feature a smooth and fine surface with well-defined patterns and fine density. In contrast, genuine leather seats have a relatively rougher surface with deeper embossing, giving a more substantial feel at first glance. 2. Cons: The most significant drawback compared to genuine leather seats is that faux leather is flammable, whereas genuine leather is not.

Is No-Deductible Insurance a Commercial Insurance?

No-deductible insurance refers to an additional coverage that can be added to a commercial insurance policy (such as auto damage insurance or third-party liability insurance). Here are the relevant details: 1. Prerequisite: As an add-on coverage, no-deductible insurance requires the policyholder to first purchase a "main insurance" policy and cannot be purchased separately. 2. Coverage: Its insurance liability typically means "as specially agreed, after an accident occurs, the insurance company will be responsible for compensating the deductible amount (calculated according to the deductible rate stipulated in the main insurance policy clauses) that should be borne by the insured within the liability limit." Generally speaking, by purchasing this coverage, the policyholder can transfer the 5% to 20% compensation liability that would originally be their responsibility to the insurance company.
