Why Does the Steering Wheel Vibrate During Sudden Acceleration?

Is a tire pressure of 2.7 high in winter?

Winter tire pressure of 2.7 bar is not high. According to the provisions and requirements of the international GBT2978-2008 standard, the standard tire pressure is 2.4-2.5 bar. In winter, it is appropriate to increase the pressure by about 0.2 bar. Therefore, a tire pressure of 2.7 bar is not high. Hazards of excessive tire pressure: The friction and adhesion of the tire will decrease, affecting braking performance; It can cause steering wheel vibration and deviation, reducing driving comfort; Accelerates localized wear of the tread pattern in the center of the tire, reducing tire life; Increases body vibration, indirectly affecting the lifespan of other components; Causes excessive stretching and deformation of tire cords, reducing tire elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance. When encountering sharp objects such as nails or glass on the road, they can easily penetrate the tire, and impacts can cause internal cracks and explosions, leading to blowouts.

Can High Temperature Damage the Cylinder Head Gasket in One Instance?

Short-term high temperature will not damage the cylinder head gasket. Engine operating for a long time: When the engine operates under heavy load for extended periods, frequent detonation combustion occurs, leading to localized high temperature and pressure in the cylinder, which can erode the cylinder head gasket. Improper bolt installation: When tightening the cylinder head bolts, if not operated according to the specified requirements, uneven torque can cause the cylinder head gasket to not lie flat against the joint surface between the cylinder block and the cylinder head, resulting in gas leakage. Excessive advance angle: Excessive ignition advance angle or fuel injection advance angle increases the cycle pressure and temperature too much. Poor quality cylinder head gasket: The cylinder head gasket is of poor quality and uneven in thickness; there are air pockets inside the sealing edge, uneven asbestos distribution, or loose wrapping.

What are the requirements for upgrading from a C1 to an A3 driver's license?

The requirements for upgrading are as follows: Age: Must be at least 21 years old. Residency: Must study in the place of residence (within the prefecture-level city of the registered residence). Study is not permitted in temporary residence locations. If the original driver's license is from another region, it must be transferred back to the original place of residence, and study must be conducted there. Physical conditions: For large vehicles, the height must be at least 1.55 meters; for A3, corrected vision must be 5.0. Must have held a C1 driver's license for at least one year. No record of accumulating 12 penalty points in a single scoring cycle. C1 Driver's License: The C1 driver's license is one of the codes for motor vehicle driver's licenses. The scope of vehicles permitted under a C1 license includes small and mini passenger vehicles, as well as light and mini cargo vehicles; light, small, and mini special-purpose vehicles; and small passenger vehicles with a seating capacity of 9 or fewer people. Application Age: The minimum age requirement for a C1 driver's license is 18 years old, with no upper age limit. However, applicants aged 70 or older must pass tests for memory, judgment, and reaction abilities.

What does highway ETC refer to?

Highway ETC (Electronic Toll Collection) translates to electronic toll collection, which is a non-stop toll collection system. On highways, there will be one or more ETC lanes. ETC charging method: Through microwave-specific short-range communication between the onboard RFID tag installed on the vehicle's windshield and the microwave antenna on the ETC lane at the toll station, the system uses networked technology to conduct background settlement processing with the bank. This achieves the purpose of vehicles passing through bridge and road toll stations without stopping to pay toll fees. Banks install this type of ETC express card with a post-payment system. ETC application conditions are as follows: Provide the original and photocopy of the vehicle owner's valid ID card and vehicle registration certificate. The photocopy of the driving license should include the page with the most recent annual inspection stamp. Fill out a bank debit card application form, which will be used to bind the ETC card. After receiving the card, you can go to a designated bank branch to collect and install the ETC onboard device for free, with no additional charges. Applicants must be between 18 and 60 years old and own a vehicle in their name. Required documents for company vehicles: An introduction letter from the vehicle owner (with official seal); photocopy of the organization code certificate or business license (with official seal); original ID of the agent; original vehicle registration certificate; the vehicle that needs to apply for ETC. Here are the precautions for installing ETC: Do not block the driver's line of sight. It is best to install it behind the rearview mirror: Many car models have a steeply angled windshield, which reduces the driver's field of vision. If ETC installation does not consider this, it may increase blind spots. Install it on the right side behind the rearview mirror to avoid obstructing the view. Do not interfere with charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement because it has a solar panel on the back for self-charging. Therefore, avoid installing it on the blackened areas of the windshield or positions that may block the solar panel. Do not remove it randomly 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 removed arbitrarily, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. You will need to visit an ETC service point to unlock it. This mechanism is designed to prevent multiple vehicles from sharing one device.

Is it necessary to turn off the automatic air conditioning AC button all the time?

Automatic air conditioning AC button needs to be turned off when not in use. How to use the A/C button: When the weather is hot and you need to turn on the air conditioning to cool down, press the AC button, adjust the temperature selection knob to the blue part, then turn on the fan switch. When the indicator light on the button is on, the car air conditioning compressor starts working, and cold air will blow out from the vents. How car air conditioning works: After turning on the air conditioning vent, the air conditioning will blow air because the blower in the air conditioning system starts working at this time. However, the air conditioning cooling system has not yet started because the air conditioning compressor has not begun to work.

Why is it not recommended to fill up the car with fuel?

Here are the reasons why it is not recommended to fill up the car with fuel: Fuel leakage leads to waste and safety hazards: Gasoline storage at gas stations is very strict, especially in hot summers. Gasoline is stored underground where the temperature is kept very low. If the car is filled with fuel, it is likely to overflow from the vent hole, which not only causes waste but also poses a fire hazard if the spilled gasoline comes into contact with an open flame. Damage to the carbon canister: The carbon canister is usually installed between the fuel tank and the engine. Since gasoline is a volatile liquid, the fuel tank often contains vapor at room temperature. The fuel evaporation emission control system is designed to introduce the vapor into combustion and prevent it from volatilizing into the atmosphere. The activated carbon canister storage device plays a crucial role in this process. If the fuel tank is filled too much, liquid gasoline instead of gasoline vapor enters the carbon canister, which can damage it. Vent hole blockage: If the engine fails to start after refueling or if the car jerks while driving, don’t suspect the quality of the fuel. It is likely caused by an overfilled fuel tank. Once the vent hole is blocked, negative pressure will form inside the fuel tank, leading to poor fuel supply or even a complete lack of fuel supply.
