How to Determine if a Car is Pulling to One Side?

When driving on a flat road, take both hands off the steering wheel and drive straight for 100 meters. If the car does not drive in a straight line, it is pulling to one side. The reasons for a car pulling to one side are as follows: 1. Uneven load distribution: This mainly refers to whether the trunk has been carrying heavy items concentrated on one side. If so, moving them to the center can help. 2. Uneven tire pressure on both sides: The solution is to inflate both tires to the standard pressure. Additionally, check if the wear on both wheels is uneven, causing differences in wheel diameter and traction. 3. Damaged springs and shock absorbers: Focus on inspecting the lower side to see if the spring is overly compressed due to insufficient elasticity or if the shock absorber is leaking oil. If there are indeed issues, repair or replace them as needed. When replacing springs, always change both sides together; otherwise, it will create a new imbalance.

What is the fuel tank capacity of the 2013 Buick GL8 in liters?

2013 Buick GL8 has a fuel tank capacity of 77 liters, using 92-octane or higher unleaded gasoline. It is an MPV model under SAIC-GM Buick. Among similar models, the Honda Odyssey has a 50-liter fuel tank capacity, while the Trumpchi M8 has a 65-liter fuel tank. To check the remaining fuel level, owners can observe the fuel gauge on the right side of the dashboard, marked with E and F. When the needle approaches E, it indicates low fuel, while nearing F means sufficient fuel. Fuel tank maintenance includes: Draining accumulated water and sediment from the tank, and checking for oil leaks at pipe joints and switches. For fuel tank caps equipped with air and vapor valves, ensure the vent holes are unobstructed. The filler inlet filter should remain intact to prevent impurities from entering the tank during refueling and clogging the fuel lines. The sealing gasket on the fuel filler cap should also be intact to prevent fuel spillage while driving.

What is Oil Burning?

Oil burning refers to the situation where engine oil enters the combustion chamber of the engine and participates in combustion along with the air-fuel mixture. Here are the relevant details: 1. Consequences of oil burning: If a vehicle exhibits oil burning, it can lead to rapid damage of the oxygen sensor, increased carbon deposits in the combustion chamber, unstable idling, reduced acceleration power, increased fuel consumption, excessive exhaust emissions, and other adverse effects. 2. Factors causing oil burning: Aging and failure of the valve stem seals can allow oil to enter the combustion chamber through the gap between the valve stem and the guide hole under the influence of intake manifold vacuum, resulting in combustion.

What is the working principle of engine braking?

The working principle of engine braking is as follows: 1. The higher the gear, the smaller the gear ratio: Due to the presence of the transmission, different gears have different "gear ratios," and the higher the gear, the smaller the gear ratio. For example: During normal driving, when in first, second, or third gear, the engine turns 100 times while the wheels turn 5, 10, and 20 times respectively. Since the wheel circumference is constant, the higher the gear, the longer the distance covered per unit of time, meaning the faster the speed. 2. The lower the gear, the more noticeable the drag effect: Engine braking utilizes the drag effect of the engine to slow down the vehicle. The lower the gear, the more noticeable the drag effect and the stronger the braking performance. When driving on long downhill roads, shifting into a lower gear and using the engine's drag effect can reduce the burden on the brakes and the frequency of braking, preventing brake overheating and subsequent thermal fade. When driving on snowy or muddy roads, using engine drag braking can help prevent skidding.

How often should the oil in a CVT transmission be changed?

CVT transmission fluid generally needs to be replaced every two years or every 40,000 kilometers driven. Here is some relevant information about transmissions: 1. Main functions: Change the transmission ratio to expand the range of torque and speed variations of the drive wheels, adapting to frequently changing driving conditions while keeping the engine operating under favorable conditions. It allows the vehicle to reverse while maintaining the engine's rotational direction. By using neutral gear, it interrupts power transmission, enabling the engine to start, shift gears, and facilitating gear changes or power output. 2. Working principle: Manual transmissions mainly consist of gears and shafts, achieving speed and torque variations through different gear combinations. Automatic transmissions (AT) are composed of a torque converter, planetary gears, and a hydraulic control system, achieving speed and torque variations through hydraulic transmission and gear combinations.

Which is safer, electronic parking or handbrake parking?

Handbrake is relatively safer. As a mechanical auxiliary braking system, the handbrake can serve as a last resort in emergencies, such as a complete power failure during high-speed driving, potentially saving lives—something electronic parking cannot achieve. Below is more information about handbrakes: 1. Auxiliary Brake: The technical term for a handbrake is an auxiliary brake. Unlike the main braking system, it uses a steel cable connected to the rear brake shoes to apply braking force. 2. Steel Cable Plastic Deformation: Prolonged use of the handbrake can cause plastic deformation in the steel cable. Since this deformation is irreversible, long-term use reduces its effectiveness and increases the handbrake's travel distance. 3. Return Spring: The handbrake system also includes a return spring. When the handbrake is engaged, the spring stretches, and when released, it returns to its original length. Over time, the spring may also undergo deformation due to prolonged use.
