What Causes the Steering Wheel to Suddenly Become Lighter and Lose Feel When Turned to Full Lock?

What does the approach angle of a car mean?

The approach angle refers to the angle between the ground and a line drawn from the frontmost protruding point of the car to the front wheel when the car is fully loaded and stationary. Here is some relevant information: 1. Concept: It is the maximum angle between the horizontal plane and a plane tangent to the outer edge of the front tire (under static load). Any rigid component fixed to the vehicle in front of the front axle must not be below this plane. 2. Function: The approach angle is one of the indicators used to measure a car's off-road performance. A larger approach angle makes it less likely for the front end to scrape against obstacles. This parameter alone does not completely determine a vehicle's off-road capability; other parameters and actual conditions must also be considered. The approach angle is not only important for SUVs; sedans also need a certain level of off-road capability. Situations like driving onto curbs, small steep slopes, or boarding ferries can be encountered in daily use, and a larger approach angle helps prevent the front end from scraping.

What Components Make Up an Automotive Air Conditioning System?

An automotive air conditioning system consists of a refrigeration system, heating system, ventilation and air purification devices, and a control system. The automotive air conditioning system is designed to cool, heat, ventilate, and purify the air inside the vehicle cabin. It provides a comfortable environment for passengers, reduces driver fatigue, and enhances driving safety. More details about automotive air conditioning are as follows: 1. Refrigeration System: Cools or dehumidifies the air inside the cabin or fresh air entering from outside, making the cabin air cool and comfortable. 2. Heating System: Primarily used for heating, it warms the air inside the cabin or fresh air entering from outside to achieve heating and dehumidification. 3. Ventilation System: Draws fresh air from outside into the cabin for ventilation and air exchange. Additionally, ventilation helps prevent fogging on the windshield. 4. Air Purification System: Removes dust, odors, smoke, and toxic gases from the cabin air, keeping it clean. 5. Control System: Regulates the temperature and pressure of the refrigeration and heating systems, while also controlling the cabin air's temperature, airflow rate, and direction to ensure the proper functioning of the air conditioning system.

What are the precautions for safe driving during the rainy season?

The precautions for safe driving during the rainy season are: 1. Maintain a sufficient safe driving distance; 2. Avoid restarting the vehicle after stalling; 3. Turn on the fog lights when driving; 4. Stay away from bicycle lanes; 5. Prevent engine water intake; 6. Drive slowly in low gear; 7. Prevent wheel skidding. Methods to defog during the rainy season include: 1. Use air conditioning to defog by blowing cold air towards the front windshield and utilizing the dehumidification function to remove fog; 2. Use detergent-type anti-fog solutions; 3. Apply anti-fog spray on the fogged windshield and wipe it dry with a cloth for immediate clarity; 4. Use rain deflectors to guide airflow and reduce wind resistance, directing air to the rearview mirrors to accelerate evaporation of water droplets and fog; 5. Use the external air circulation to defog; 6. Use rear window heating to defog; 7. Open the window slightly to allow air convection and reduce temperature differences.

Is It Safe to Sleep in a Car with the Engine Off?

It is possible to sleep in a car with the engine off, but it's important to avoid closing all doors and windows completely. Instead, slightly open a portion of the windows. Studies indicate that when carbon dioxide concentration in a sealed vehicle reaches 1%, the body may experience mild poisoning symptoms, including brain hypoxia and unconsciousness. At levels exceeding 3%, breathing difficulties occur, and concentrations above 6% can be fatal, especially during deep sleep when individuals may not wake up even when called. Therefore, sleeping in a car with the engine off poses certain risks and is detrimental to health. Here are some precautions for sleeping in a car: 1. Ensure proper ventilation and warmth: Partially open a window or door. However, it is not advisable to sleep in a new car due to the presence of harmful substances like formaldehyde in leather and fabrics, which can be carcinogenic. 2. If idling with the air conditioning on, avoid using the recirculation mode: Incomplete fuel combustion produces carbon monoxide, which can accumulate inside the car and lead to fatal poisoning. It's recommended to partially open windows to allow air circulation. 3. Take breaks of at least 20 minutes after driving for 4 hours: However, do not stop and sleep on the highway emergency lane, as this often leads to rear-end collisions.

What to Do When the Steering System Fails?

When a car's steering system malfunctions, it should be inspected promptly. Common issues include excessive steering wheel rotation, unstable handling, front wheel wobbling, veering, and heavy steering. Key areas to check when the steering system fails are: 1. Inspect whether the worm gear and worm in the steering gear are severely worn or have excessive clearance; 2. Check if the connecting parts of the steering mechanism are severely worn or too loose; 3. Verify if the steering gear mounting points are loose; 4. Examine whether the steering arm is loose; 5. First, check the wheel's dynamic balance, ensuring the balance weights are correctly installed, then verify proper tire installation and even wear. Inspect if the wheel rim is deformed, if there's lateral or radial wobble, and if the tire pressure is correct; 7. Check for looseness in the steering knuckle bearings, looseness in the tie rod ball joints, and any assembly looseness in the steering gear. Also, inspect the U-bolts and center clamping bolts of the leaf springs for looseness or damage, and check for residual deformation in the leaf springs.
