What is the purpose of car polishing?

Polishing is used for vehicle paint surfaces that have oxidation, dullness, or scratches. It can remove oxides and corrosive substances, restoring the cleanliness of the paint surface. Below is more related information: 1. Car Polishing: Car polishing is a step in the car detailing process, performed before waxing, sealing, or coating. This is because paint sealing or coating must first undergo polishing—specifically, fine polishing—to achieve a mirror-like finish. This is an essential step in the sealing process. Without polishing, the paint surface will not be smooth, and the sealing effect will be short-lived, failing to provide long-term adhesion. In such cases, it would be no different from regular waxing. 2. Prospects of Car Polishing: Currently, the demand for car polishing is high, while the supply is somewhat insufficient. There are particularly few companies with core intellectual property rights and high-quality products, and the industry as a whole lacks brand recognition. During this period of strong demand, the industry has enormous potential and promising prospects—this is undeniable. 3. Precautions for Polishing: Avoid frequent full-car polishing, as it can damage the paint. It is recommended not to perform full-car polishing on new vehicles within the first two years—minor localized scratches can be addressed instead. Older vehicles may undergo full-car polishing depending on their condition. The key is regular waxing: for cars parked outdoors or for enthusiasts, monthly waxing is advisable. DIY waxing is convenient and easy to perform.

Why Did My Car Battery Suddenly Die?

Car batteries can suddenly die due to reasons such as complete battery discharge, insufficient electrolyte levels, internal battery faults leading to damage, etc. Typically, a car battery has a lifespan of around 3 to 4 years, which can vary based on the user's driving habits and the vehicle's operating conditions. Relevant information about car batteries is as follows: 1. Introduction: A car battery, also known as a storage battery, is a type of battery that works by converting chemical energy into electrical energy. Commonly referred to as lead-acid batteries, they are primarily made of lead and its oxides, with a sulfuric acid solution serving as the electrolyte. 2. Working Principle: The battery uses lead plates filled with sponge lead as the negative electrode, lead plates filled with lead dioxide as the positive electrode, and a 22-28% dilute sulfuric acid solution as the electrolyte. During charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted back into electrical energy.

Where is the OBD interface located on the new Excelle?

The OBD interface of the Excelle is located above the left side of the brake pedal. There is a bundle of wires; pull it out, and the OBD interface will be there. Below is some relevant information about the Excelle's OBD: 1. OBD: OBD is translated into Chinese as "On-Board Diagnostics." This system continuously monitors the engine's operating conditions to check if the vehicle's emissions exceed the standard. If they do, it will immediately issue a warning. When a fault occurs in the system, the Malfunction Indicator Lamp (MIL) or Check Engine warning light will illuminate. At the same time, the Powertrain Control Module (PCM) stores the fault information in memory. Through a specific procedure, the fault code can be read from the PCM. Based on the fault code, maintenance personnel can quickly and accurately determine the nature and location of the fault. 2. The development of OBD: In its later development, OBD gradually expanded its control scope. With the increase in various sensors and the level of electronicization in vehicles, OBD has incorporated various monitoring functions into its jurisdiction. Nowadays, when people refer to OBD, they generally use the term "OBD interface" because only the transmission interface of this system is visible on the vehicle, but it represents the collective body of the vehicle's control system.

Does Car Heater Consume Fuel?

Using the heater theoretically does not consume fuel. The heater utilizes the heat from the engine's coolant to raise the temperature, which is then circulated to the small radiator. When the blower operates, it blows the heat from the small radiator into the car, resulting in a relatively small load. There is a slight difference in fuel consumption compared to when the heater is not used, but it is generally negligible. Here is additional information: 1. When the air conditioning is in cooling mode, the compressor system works, increasing the engine's load. Continuous use will raise the engine's fuel consumption. 2. However, during heating, the compressor does not engage, so the engine does not need to provide additional power, thus not increasing fuel consumption.

Can ETC be fraudulently charged?

ETC has the risk of being fraudulently charged, so it is recommended to remove the ETC card when parking to prevent fraudulent charges. Precautions for using ETC: The ETC transaction sensing range is 8 meters. When encountering a stationary vehicle ahead, to prevent the ETC device of the front vehicle from malfunctioning or not having an ETC device at all, maintain a distance of more than 10 meters from the front vehicle to avoid automatic sensing and paying for the front vehicle. The recognition speed for ETC lanes is 20km/h. If the speed is too fast, the vehicle device information cannot be read, which will also result in a failed charge. Unauthorized removal or movement of the OBU device, detachment or loosening of the ETC electronic tag, etc., will cause the electronic tag to become invalid. It can be sent to the bank where the ETC card was issued or the highway service office for inspection. If the loosening or detachment is not due to human factors, it only needs to be reactivated. When using a debit card to bind with ETC, insufficient balance will also result in a failed charge. Follow the guidance of on-site staff to use the manual MTC lane and pass by using cash or card. Poor sensing due to excessively thick car windshield. Especially for vehicles that have had accidents and had their windshields replaced, or for friends who have modified their front windshields, extra attention is needed.

Do I Need to Bring a Driver's License When Buying a Car?

You do not need to bring a driver's license when buying a car. Purchasing a car is a commercial transaction, and you can buy a car even without a driver's license. Even when registering the vehicle, a driver's license is not required for review. In other words, you can complete the vehicle registration process without a driver's license by filling out the "Motor Vehicle Registration Application Form" and submitting the necessary documents. These documents include: 1. Identification: Proof of identity of the vehicle owner; 2. Photo: Standard photo of the vehicle for registration; 3. Proof of origin: Documentation proving the origin of the vehicle (excluding customs-regulated vehicles); 4. Certificate of conformity: Factory certificate of conformity for domestically manufactured vehicles; 5. Import documentation: Import documentation for imported vehicles.
