What does the commonly mentioned torque in cars mean?

Torque, often referred to in cars, is the engine's torque, which refers to the rotational force output from the crankshaft. Under a fixed power condition, it has an inverse relationship with the engine's rotational speed—the faster the speed, the smaller the torque, and vice versa. Torque reflects a car's load-bearing capacity within a certain range. Like power, torque is one of the main indicators of a car's engine, influencing performance aspects such as acceleration, climbing ability, and suspension. For family cars, higher torque means better acceleration; for off-road vehicles, higher torque allows for steeper climbs; for trucks, higher torque enables carrying heavier loads. Generally, the higher the torque, the better the car performs, especially when comparing engines of the same displacement—higher torque indicates a superior engine.

What to Do When the Car Battery Dies After Long-Term Parking?

Solutions for a dead car battery after long-term parking: 1. Use jumper cables from another vehicle to charge your car battery; 2. Utilize a portable charger to recharge the battery. Common reasons for a dead car battery include: 1. Failure to disconnect the battery power supply during long-term parking, as the car's electrical components continue to drain the battery, and the battery itself has a self-discharge characteristic; 2. The battery has reached the end of its lifespan, and the solution is to replace it; 3. Insufficient battery electrolyte or leakage, so it is recommended to regularly check the electrolyte level during maintenance.

Why does the steering wheel shake after changing tires?

The reason for steering wheel shaking after changing tires: After replacing tires, the weight of each tire cannot be completely uniform. At high speeds, the wheels will become unbalanced, leading to vehicle deviation and steering wheel vibration. It is necessary to perform wheel balancing every time after changing tires to effectively solve this issue. Tires are circular elastic rubber products mounted on vehicles or machinery for ground rolling, usually installed on metal rims. They support the vehicle body, absorb external impacts, ensure contact with the road surface, and maintain driving performance. Tires often operate under complex and harsh conditions, enduring various deformations, loads, and temperature extremes during driving. Therefore, they must possess high load-bearing capacity, traction performance, and cushioning ability.

How to Apply for a Car ETC?

ETC can be applied for at bank branches, highway service areas, and other institutions. To apply, you need to provide the original and photocopies of the vehicle owner's valid ID card and vehicle license. If the application is not made by the owner, the agent's valid ID card must also be provided. The photocopy of the vehicle license should include the page with the most recent annual inspection seal. Additionally, a Postal Savings credit card application form is required, as the credit card will be used to bind the ETC card. After obtaining the credit card, you can swipe it twice and use the POS receipt to collect and install the ETC onboard device for free at designated Postal Savings outlets. No fees are charged during this process. Applicants must be between 18 and 60 years old and own the vehicle in their name. ETC stands for Electronic Toll Collection, which refers to the electronic toll system. The required documents for application include the original and photocopies of the vehicle owner's valid ID card and vehicle license. If the application is not made by the owner, the agent's valid ID card must also be provided. The photocopy of the vehicle license should include the page with the most recent annual inspection seal. A bank card for deducting highway toll fees is also required. Applicants must be between 18 and 60 years old and own the vehicle in their name. Here are some precautions for installing ETC: Do not obstruct the view; it is best to install it behind the rearview mirror: Many car models have a steeply angled windshield, which can reduce the driver's field of vision. If this is not considered during ETC installation, it can increase the driver's blind spots. Installing it behind the rearview mirror on the right side can help avoid obstructing the view. Do not interfere with charging: The ETC electronic tag requires power but generally does not need to be charged or have its battery replaced, as it has a solar panel on the back for self-charging. Therefore, during installation, avoid the blackened areas on the windshield and positions that might block the solar panel. Do not remove it arbitrarily once installed: The button in the middle of the adhesive is an anti-removal lever connected to a switch. After installation, the windshield will press the anti-removal lever in. If the tag is removed arbitrarily, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. You would then need to visit an ETC service point to unlock it. This mechanism is designed to prevent multiple vehicles from sharing one device. When using ETC, note the following: The ETC transaction sensing range is 8 meters. To prevent issues caused by the ETC device of the vehicle in front malfunctioning, maintain a distance of more than 10 meters from the vehicle ahead to avoid automatic toll payment for the wrong vehicle. The ETC lane recognition speed is 20 kilometers per hour. Driving too fast may result in failure to read the vehicle's device information, leading to toll deduction failure. If a debit card is used to bind the ETC, insufficient balance may also cause toll deduction failure.

What Causes the Ticking Sound After a Car Engine Shuts Off?

Reasons for the ticking sound after a car engine shuts off: While driving, the engine exhaust is very hot, and components like the exhaust pipe, catalytic converter, and muffler become extremely hot. After stopping and turning off the engine, the exhaust pipe begins to cool rapidly, causing the metal to expand and contract, resulting in a ticking sound. If it's a turbocharged engine, especially after a long-distance drive, the exhaust turbine is connected to the exhaust manifold, which reaches very high temperatures. It's recommended not to shut off the engine immediately; instead, let it idle for two to three minutes to help cool the turbo. In new cars, the muffler is cleaner with no carbon deposits, making the sound more distinct, whereas in older cars, the sound may be less noticeable or absent.

What causes the excessive resistance of the driver's airbag?

The excessive resistance of the driver's side airbag may be due to a loose connector of the airbag. It is recommended to securely fasten the airbag connector under the driver's seat. Here is a partial introduction about the side impact airbag system: 1. It mainly consists of an airbag sensor, an impact airbag, and an electronic control unit. 2. The driver's side impact airbag is located in the steering wheel, while the passenger side impact airbag is usually installed on the dashboard. 3. The airbag sensors are installed on the left, right, and center partitions of the cabin. The central airbag sensor and the airbag system are integrated with the electronic control unit.
