Why is it not advisable to overtake in rainy weather?

When driving in the rain, always pay attention to the speed and direction of the vehicle in front, and never accelerate to overtake just because the vehicle ahead is moving slowly. Especially on highways, where the speed of vehicles in each lane is relatively high, the driver's field of vision narrows. Coupled with slippery road surfaces, forcibly changing lanes to overtake can easily cause the wheels to skid with just a slight turn of the steering wheel, leading to collisions with other vehicles or even rollover accidents. The specific reasons are as follows: 1. Difficulty in judging distance: It becomes hard to accurately assess the distance to surrounding vehicles. 2. Poor visibility of overtaking signals: Drivers of nearby vehicles may not easily see overtaking signals. 3. Slippery roads: Vehicles are prone to skidding. 4. Other factors: It becomes difficult to promptly detect dangerous situations.

Why can't the car door be opened?

The reasons why the car door cannot be opened are as follows: 1. Remote control failure: mainly due to unresponsive buttons, low battery, environmental factors, strong signal interference or shielding, anti-theft system malfunction, or the need to re-match the remote control encryption. 2. Car door frozen in winter: In northern regions, winter temperatures are very low, often below freezing. After washing the car, residual water can accumulate in the door handle, lock, door frame gaps, etc. Overnight freezing turns the water into ice, firmly freezing the door shut, making it impossible to open in the morning. 3. Fault in the door lock mechanism itself: The probability of the door lock itself failing is very low, mostly occurring in older cars around 10 years old. No matter how high-end the car is, its working principle may not be commonly understood, but the structure of the door lock is relatively simple, basically consisting of a lock cylinder, lock block, central control motor, and operating mechanism.

What is the load capacity of a 700r16 tire in tons?

700r16 tires can carry approximately 5 tons. Generally, the load index of a vehicle is molded on the sidewall of the tire, indicating the maximum load capacity of the tire. For driving safety, this load limit should not be exceeded. In 700r16, 700 refers to the nominal section width of the tire, and 16 indicates that the diameter of the car wheel hub is 16 inches. The following are factors related to vehicle load capacity: 1. Vehicle category: Heavy-duty trucks have a higher maximum load capacity than mini trucks. 2. Length: Generally, the longer the truck, the greater the weight it can carry. 3. Design weight: Each truck is designed with its own load capacity, and depending on the type of truck and the materials used in its design, there can be significant differences in load capacity. 4. Power: Generally, the larger the engine displacement of a truck, the greater its power, and thus the greater the weight of cargo it can carry.

What is the typical transmission efficiency of a CVT?

Manual transmissions have the highest efficiency, reaching up to 98%; dual-clutch transmissions rank second with an efficiency of up to 96%; AT transmissions have an efficiency of 91%; while CVT transmissions have an efficiency of 87%. Below is an introduction to automotive transmissions: Transmission: A device that changes the speed ratio and direction of motion. Used in automobiles, tractors, ships, machine tools, and various machinery, it alters the torque, speed, and direction of motion transmitted from the driving shaft to the driven shaft under different working conditions. Gear-driven transmissions generally consist of a housing and several gear pairs. Function of the Transmission: While driving, to adapt to different operating conditions, a vehicle's driving force and speed need to vary within a certain range. However, the torque and speed variation range of existing engines cannot meet this requirement, hence the installation of a transmission.

Why is the D941 bullet train sometimes available and sometimes not?

Shanghai to Zhuhai D941 bullet train runs daily. The D941 is a high-speed EMU (Electric Multiple Unit) from Shanghai Hongqiao to Zhuhai, covering a distance of 1841 kilometers and taking 12 hours and 34 minutes. Below is an introduction to the D941 bullet train: Bullet Train: Bullet train, fully known as powered vehicle, refers to vehicles equipped with power devices in rail transit systems, mainly including locomotives and powered carriages. Bullet trains are equipped with driving wheels, while vehicles without driving devices are called trailers. For a train to operate normally on the tracks, there must be bullet trains to provide sufficient traction for the entire train, but it is possible not to attach trailers without power. D941: The D941 is a high-speed bullet train from Shanghai Hongqiao to Zhuhai, covering a total distance of 1841 kilometers and taking 12 hours and 34 minutes. The departure time is 19:55, and the arrival time is 08:29.

How is the oil quality at illegal gas stations?

Illegal gas stations cannot guarantee the source channels and quality of their oil products, often selling substandard fuel with unassured quality. Here are detailed explanations of relevant information: Hazard information: Inaccurate measurements cheat the fuel tank. Using such oil can cause engine carbon buildup, clog the fuel system, and lead to failure of the vehicle's oxygen sensor and three-way catalytic converter. Difficulties in rights protection cheat customers, excessive emissions harm the environment, and tax evasion cheats the nation. Illegal gas stations operate without licenses and evade tax responsibilities. Precautions: Driven by profit, illegal gas stations mostly sell inferior diesel, far below the national China V standard. Oil quality test results consistently show non-compliance.
