How to Correct Direction for Front Wheel Skid and Rear Wheel Skid?

When the front wheels skid, the steering wheel should be corrected in the opposite direction; when the rear wheels skid, the steering wheel should be corrected in the direction of the skid, and the vehicle should return to the road after the rear wheels are straightened. Vehicle skidding refers to the phenomenon of sudden acceleration or sudden lateral swinging, which is more likely to occur on curves or in rainy or snowy weather. If a skid suddenly occurs while driving, the driver should try to stay calm, hold the steering wheel firmly with both hands, quickly identify which tire is skidding, immediately release the brake pedal, and swiftly turn the steering wheel in the direction of the skid. On icy or snowy roads, drivers should never use emergency braking. Emergency braking not only fails to stop the vehicle but can also accelerate skidding or even cause the vehicle to roll over. If skidding occurs while going downhill, the driver can accelerate appropriately. If skidding occurs during a turn, the driver should slowly release the accelerator and turn the steering wheel to correct the direction, but be careful not to turn the steering wheel too much to avoid losing control and causing an accident. During a skid, do not abruptly turn the steering wheel or use the foot brake. Immediately release the brake pedal, turn the steering wheel toward the side of the skid, and promptly adjust and correct the direction before continuing to drive.

What is the foot brake?

The foot brake is the service brake. The service brake is a braking device that stops or reduces the speed of a moving vehicle. It achieves braking through intense friction between the brake pads and the brake drum. In contrast, the handbrake is a parking device and should not be used for braking during driving except in emergencies. Here is a related introduction to the classification of braking systems: 1. Throttle control braking: When deceleration is needed, maintain the 3rd gear position and fully release the throttle. At this point, the engine tends to idle, creating resistance in the drivetrain that acts on the wheels to slow the vehicle down. 2. Exhaust brake: High-power diesel engines have a butterfly valve at the connection between the exhaust manifold and the exhaust pipe. In gear, operating the electromagnetic switch closes the valve, causing the engine to stall and achieve braking. It automatically opens when the throttle is pressed again. Simple in structure but harmful to the engine. Commonly used in heavy trucks and buses. 3. Hydraulic torque converter retarder: A turbine chamber is added at the rear of the transmission housing. When the braking circuit is activated, transmission oil generates damping in the turbine to achieve braking. No wear but requires additional cooling. Currently used in ZF transmissions for high-end buses. 4. Electric turbine retarder: Essentially a "generator" installed on the driveshaft. When not powered, there is no contact or wear. When braking is needed, the circuit is activated, and the driveshaft is subjected to electromagnetic resistance to achieve braking. No wear but bulky in structure. Optional for heavy trucks and buses. 5. Engine braking structure: The braking signal slightly opens the exhaust valve without closing it, creating airflow resistance during piston movement to generate braking force. Compact and non-damaging, currently not available domestically.

What is the purpose of Subject 2 simulation training?

Subject 2 simulation is designed to mimic the formal Subject 2 driving test, aiming to improve the pass rate. The simulation covers the same test items as the actual exam, serving as a practice test. Below are some key points to note for the Subject 2 test: 1. Reverse parking into a garage: (1) Ensure accurate alignment with reference points and lines, and monitor the distance between the vehicle body and the line via the rearview mirror to prevent the body from crossing the line. (2) Do not stop the vehicle until it is completely inside the garage; pay attention to clutch control to avoid stopping midway or incomplete parking. 2. Parallel parking: (1) Maintain proper distance from the garage when aligning the vehicle, avoiding crossing the line, and be cautious not to run over the garage corner when exiting. (2) Remember to use the turn signal when exiting the garage.

How to Solve the Problem of Car Compressor Starting and Stopping Intermittently?

Here are the solutions for the issue of car compressor starting and stopping intermittently: 1. Check if the car air conditioning's energy-saving mode is activated. 2. High exhaust pressure and low suction pressure. Moisture in the system may cause pipe blockage leading to icing. Use high-pressure nitrogen to flush the pipes for repair. 3. Check the remaining amount of refrigerant. The amount of refrigerant determines the system pressure, and abnormal pressure can cause frequent starting and stopping of the compressor. 4. Appropriately increase the limit value of the high-pressure relay and decrease the limit value of the low-pressure relay. If the limit values for high and low pressure are set too high, the relay will automatically disconnect and stop working when the voltage slightly exceeds the limit.

How Many Turns to Lock the Steering Wheel for C1?

Generally, it takes two to two and a half turns to lock the steering wheel, which means turning the steering wheel to its extreme in either the counterclockwise or clockwise direction. Additional relevant information is as follows: 1. Purpose of the Steering Wheel: The steering wheel is used in automobiles and other vehicles for short-distance maneuvering, allowing the vehicle to complete significant turns with minimal movement. 2. Method of Turning the Steering Wheel: When making a turn, if the steering wheel is locked, the pressure on the power steering pump can increase several times or more. Continuously locking the steering wheel can shorten the lifespan of the power steering pump, so it should not be done persistently. Locking the steering wheel to the right means turning it one and a half turns to the right, and locking it to the left means turning it one and a half turns to the left.

How many kilometers does the Audi A6L need for maintenance?

Audi A6L new car first maintenance is recommended at 5,000 kilometers, after which it is every 7,500 kilometers. Here is the relevant introduction about the Audi A6L: 1. Vibration comfort: The new Audi A6L adopts a five-link front suspension design, balancing the necessary rigid connection for sportiness and comfort with lower static stiffness. Among them, the hydraulic form of the frame shock absorber support can significantly improve the driving comfort of the vehicle and effectively reduce the impact and jerk when passing speed bumps and uneven roads, thereby reducing the impact on the lumbar spine. 2. Interior: In terms of interior, the new generation A6L comes standard with the Audi virtual cockpit, equipped with a 10.1-inch display screen, an 8.6-inch touch screen below, and a 12.3-inch full LCD instrument panel. It is worth mentioning that the new generation model will be equipped with the latest MMI system, providing intelligent search suggestions, voice control, Car-to-X services, and other functions.
