Is it bad luck if tires get punctured frequently?

Tires getting punctured frequently is not necessarily due to bad luck; it could be related to driving habits. Driving too close to the roadside often increases the risk because many foreign objects fall from large vehicles and are then pushed toward the roadside by the movement of these vehicles, especially items like nails, stones, and metal sheets. Below is some relevant information about tires: Main materials: The primary material of tires is rubber, which naturally ages over time or with prolonged storage. This aging causes noticeable changes in the tire's physical properties, such as hardness and wear resistance. Continuing to use aged tires can mildly affect vehicle performance or, in severe cases, lead to tire blowouts. Lifespan: Typically, all-season or economy tires have a lifespan of 3-5 years or around 50,000 kilometers. Under normal conditions, a tire's lifespan from the date of manufacture is sufficient for one year of use. However, for high-performance tires, the lifespan may only be 20,000-30,000 kilometers. If prices drop, purchasing these tires might also be a consideration.

How much can the throttle be pressed in first gear when going uphill?

When going uphill in first gear, it's best to keep the speed around 20 km/h, maintain a steady throttle, and keep the engine speed around 2000 RPM. Here is some relevant information about the car throttle: Function: In gasoline engines, the throttle does not control the fuel injection volume but rather the opening degree of the throttle valve. A smaller opening means less air-fuel mixture enters the cylinder, resulting in lower engine power output, and vice versa. Solution for a heavy throttle: If the throttle feels heavy, you can perform a fuel system cleaning. Alternatively, try accelerating further to see if the engine speed increases but the speed does not. If this happens, it might be due to a damaged sensor in the transmission locking the overdrive gear.

Can ETC still be used after changing to a new license plate?

ETC cannot be used if the vehicle information it is bound to is inconsistent. Different types of vehicles have different highway toll fees. According to the "Rules for the Use of Non-Stop Rapid Passage Systems," when applying for ETC, the ETC card and OBU device are already bound to the vehicle, and the relevant vehicle information is imported, forming a one-to-one correspondence. If you change to a new vehicle with a new license plate, you need to cancel the original ETC and reapply for the new vehicle. If it's a new vehicle with the old license plate, you can simply update the vehicle information at an offline service center. ETC is a non-stop electronic toll collection system. ETC lanes are set up for vehicles equipped with ETC onboard devices and use electronic tolling. The electronic toll collection system is an automatic toll system for highways or bridges. ETC deduction principles: There will be one or more ETC lanes on highways. Through microwave-specific short-range communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, and using computer networking technology for backend settlement with the bank, the system achieves the purpose of vehicles not needing to stop at toll stations to pay bridge or road fees. All of this is based on the principle of passing first and deducting fees later. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line. Green and eco-friendly: Low-carbon, as vehicles pass through toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution. Reduced wear and tear: Saves costs by reducing the frequency of vehicle starts and brakes, lowering wear and fuel consumption. Improved efficiency: Theoretically, ETC lanes can improve traffic efficiency by 2-3 times, making traditional ETC faster, newer, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council explicitly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, the interoperability of transportation cards in key city clusters will be basically achieved, and the proportion of vehicles equipped with ETC will significantly increase." It also set a clear target in the "13th Five-Year" comprehensive transportation development indicators: "By 2020, the ETC usage rate for road passenger vehicles will reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and increasing the ETC adoption rate for passenger vehicles, efforts will be made to promote ETC usage for trucks in the future. There will also be exploration into deeper integration between the ETC system and smart transportation development directions such as vehicle-to-vehicle communication and vehicle-road coordination, providing comprehensive travel services for car owners. This means more application scenarios will support ETC usage. ETC usage precautions: The ETC transaction sensing range is 8 meters. If the vehicle in front stops, 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 to avoid automatic sensing and paying for the front vehicle. The recognition speed for ETC lanes is 20 km/h. If the speed is too fast, the vehicle device information cannot be read, leading to failed deductions. Unauthorized removal or movement of the OBU device, or if the ETC electronic tag falls off or becomes loose, will cause the electronic tag to fail. It can be taken 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, reactivation is sufficient. When using a debit card bound to ETC, insufficient balance can also lead to failed deductions. Follow the guidance of on-site staff to use the manual MTC lane and pass through by paying cash or swiping a card. If the car's windshield is too thick, it may cause poor sensing. This is particularly important for vehicles that have had accidents and had their windshields replaced or for those who have modified their front windshields.

Is the Central Control Screen Not Lighting Up Due to a Fuse Failure?

If the central control screen is not lighting up, it may be due to a fuse failure caused by excessive load leading to the fuse blowing. Below is relevant information: Location: The fuse is located under the interior trim panel on the side of the main driver's central console. Its working principle involves electromagnetic induction, where the conductor cuts the magnetic field lines to generate an electric potential, converting the mechanical energy of the prime mover into electrical energy output. The fuse consists of a fuse element, electrode parts, and a support structure. Classification: Fuses can be categorized into flat-head tubular fuses, pointed-head tubular fuses, guillotine fuses, screw-type fuses, blade-type fuses, flat-plate fuses, wrapped fuses, and surface-mount fuses. Their function is to quickly melt when the circuit current exceeds twice the fuse's rated current, thereby protecting the circuit.

Why Do Cars Need to Be Driven at High Speeds?

Driving a car at high speeds helps the engine and transmission adapt more quickly to high-speed operation, improves the smoothness of components such as pistons and gears, and also aids in removing carbon deposits from the engine, especially for vehicles frequently driven in congested urban areas. After the initial break-in period, the operation between engine components becomes more coordinated. At this stage, driving at high speeds can test the machine's extreme working conditions and expand the tensile, compressive, impact, and torsional resistance range of the component materials. Performing high-speed driving after the first maintenance service is safer, as the primary purpose of the first maintenance is to conduct thorough inspections of the vehicle, ensuring better safety measures are in place.

What Happens If There Is No Antifreeze in the Car?

If there is no antifreeze in the car, it will affect the heat dissipation effect of the radiator, preventing the car from achieving the necessary cooling function and disrupting normal circulation. This can lead to engine overheating and, in severe cases, cause engine burn-out. In cold climates, it may also result in the engine or radiator freezing, leading to engine failure and rendering the vehicle unusable. Antifreeze serves multiple purposes, including anti-freezing, cooling, corrosion prevention, and scale prevention, ensuring the car can operate normally in cold weather without freezing and helping to cool down the high-temperature engine. When antifreeze is lacking, it is recommended to pull over, turn off the engine to lower the temperature, and only resume driving after the engine temperature has decreased. Driving time should not be prolonged, and antifreeze should be replenished promptly.
