Is Tire Plugging Safe?

This is the hot vulcanization repair method, which is highly reliable. It can fully ensure tire safety. However, the punctured hole should not be too large—holes smaller than 2 millimeters can be completely sealed. Additional knowledge is as follows: 1. Nails in the tread can still be used: If the tread is punctured, the tire can continue to be used. Because the tread is the thickest part of the tire, a nail will not damage the internal structure of the tire, and it can still be used after repair. 2. Nails in the sidewall cannot be used: If the sidewall is punctured, it cannot be repaired because the sidewall is the weakest part of the tire and plays a crucial role in absorbing road vibrations. Therefore, if the sidewall is punctured, the tire must be replaced. 3. Precautions: It is best to use hot vulcanization for tire repairs, as it provides the best results and is less likely to cause secondary leaks. After repair, tire dynamic balancing must be performed. If dynamic balancing is not done, it may cause steering wheel and vehicle body vibrations while driving.

What does the SPN1761 fault code mean?

SPN1761 fault code indicates a transmission malfunction. Below are the specific causes of transmission failure: 1. Solenoid valve damage: If the oil pressure solenoid valve is damaged, it can cause oil pressure to be too low or too high, resulting in a sensation of impact or lag when the clutch and brake engage. Similarly, a stuck shift solenoid valve can lead to power interruption. 2. Steel plate and friction plate burn-out: Burn-out of the clutch plate not only causes gear shift jerking but also results in weak driving performance. The debris from the friction can also contaminate the transmission fluid. 3. Transmission fluid not changed regularly: If the automatic transmission is not maintained for a long time, various performance indicators of the transmission fluid, such as lubricity, viscosity, and temperature stability, will significantly decline. Especially for the temperature of automatic transmission fluid, when the radiator is too dirty and heat cannot dissipate, the computer will detect high temperature and enter emergency operation mode. When the fluid temperature exceeds 135°, it can cause significant damage to components like friction plates and clutch plates.

Can I Check Maintenance Records If I Don't Repair My Car at a 4S Store?

This is not a question of possibility. If it was the last maintenance and this time you don't perform maintenance but directly check the last record, it should be possible. The methods are as follows: To check the maintenance records at a 4S store, if the car has the information, you can query it for free on your mobile phone. There are two other methods: 1. Go directly to the 4S store: Provide the owner's proof materials to help you check. Generally speaking, the vehicle file system of 4S stores of the same brand is nationwide networked. Just bring the owner's identity certificate, purchase invoice, and other credentials to the 4S store to find after-sales service and retrieve the car's maintenance records. 2. Online query: Use a third-party query tool, provide the VIN code, and pay to view. Now many APPs provide maintenance record queries for 4S stores.

What is the difference between high idle speed and low idle speed?

The difference between high idle speed and low idle speed lies in the different rotation speeds and fuel consumption. The following is a detailed introduction about the fuel consumption per 100 kilometers of a car: 1. Overview: The fuel consumption per 100 kilometers refers to the fuel consumption of a vehicle traveling a hundred kilometers on the road at a certain speed. It is a theoretical indicator of the vehicle. The fuel consumption per 100 kilometers is the value measured by the manufacturer in an objective environment using a dynamometer installed on the chassis of the vehicle, converted into speed parameters, and then specified speed driving is used to calculate the theoretical experimental fuel consumption data per 100 kilometers of the model. 2. Others: Since most vehicles are close to the economical speed at 90 kilometers per hour, most of the theoretical fuel consumption published externally is usually the fuel consumption per 100 kilometers at 90 kilometers per hour.

What is the role of the VCU vehicle controller?

VCU is the electronic control system of new energy vehicles. This system is the core component of new energy vehicles, equivalent to the ECU of gasoline vehicles. VCU can control the operation of the motor in new energy vehicles and also manage the operation of other electronic devices in the vehicle. VCU acts as the brain of new energy vehicles. As the central control unit of new energy vehicles, the Vehicle Control Unit (VCU) is the core of the entire control system. The VCU collects data on the motor and battery status, accelerator pedal signals, brake pedal signals, actuator and sensor signals. After comprehensive analysis based on the driver's intentions, it makes corresponding decisions and monitors the actions of lower-level component controllers. It is responsible for normal vehicle operation, brake energy recovery, energy management of the vehicle engine and power battery, network management, fault diagnosis and handling, and vehicle status monitoring. This ensures the vehicle operates stably with good dynamic performance, high economic efficiency, and reliability. It can be said that the performance of the VCU directly determines the overall performance of new energy vehicles, playing a pivotal role.

What does V2X mean?

V2X, similar to popular terms like B2B and B2C, stands for 'vehicle to everything,' which refers to the exchange of information between vehicles and the external environment. The Internet of Vehicles (IoV) has established a new direction for automotive technology development by integrating global positioning system (GPS) navigation technology, vehicle-to-vehicle communication technology, wireless communication, and remote sensing technology, achieving compatibility between manual driving and autonomous driving. Vehicles equipped with V2X can, in autonomous driving mode, automatically select the optimal driving route based on real-time traffic information analysis, significantly alleviating traffic congestion. Additionally, by using onboard sensors and camera systems, they can perceive the surrounding environment and make rapid adjustments to achieve 'zero traffic accidents.' For example, if a pedestrian suddenly appears, the vehicle can automatically decelerate to a safe speed or stop. V2X (Vehicle to X) is a key technology for future intelligent transportation systems. It enables communication between vehicles, vehicles and base stations, and base stations themselves. This allows for the acquisition of real-time traffic conditions, road information, pedestrian data, and a range of other traffic-related information, thereby enhancing driving safety, reducing congestion, improving traffic efficiency, and providing in-vehicle entertainment information.
