It is caused by issues with the engine's exhaust gas valve. Below are the relevant details: 1. Exhaust Gas Valve: After engine oil passes through the exhaust gas valve, a portion of the oil flows into the combustion chamber. Inside the combustion chamber, the oil is burned, and the residual impurities accelerate the wear of the engine piston rings, causing the oil rings to lose tension and leading to severe oil burning. 2. Function: The oil used in motor vehicles, also known as engine lubricating oil, serves to lubricate and reduce friction in the engine, as well as assist in cooling and temperature reduction. The oil in a car is often referred to as the 'blood' of the vehicle. Engine oil consists of two main components: additives and base oil.

What are the correct steps for parking an automatic transmission car?

After reaching the parking spot, press the brake pedal until the vehicle comes to a complete stop. Shift the gear lever into N (Neutral) while keeping the brake pedal pressed. Depending on the slope of the ground, such as when parking on an incline, the handbrake should be pulled tighter. Engage the handbrake and release the foot brake. If parked on a slope, the vehicle may move slightly at this point. Once the vehicle is completely stationary, press the brake pedal again and shift into P (Park). After completing these steps, exit the vehicle and lock it.

How to Brake Smoothly in an Automatic Transmission Car?

Under good road conditions, such as when approaching a traffic light at an intersection ahead, the ideal braking state is one where passengers do not feel any impact. Apply the brakes gently, but release the pedal slightly faster than on a flat road to ensure the vehicle speed does not drop excessively. Prolonged use of the brakes can cause the braking system to overheat, affecting performance. It is advisable to use engine braking simultaneously. First, always maintain a safe distance from the vehicle in front when following.

How to Turn on High Beam in an Automatic Transmission Car?

Generally, turning the switch once activates the parking lights, and turning it twice turns on the headlights. First, turn on the headlights, then push the control lever upward and hold it in position for a few seconds to switch to high beam. Similarly, with the high beam already on, pushing the control lever upward and holding it for a few seconds will maintain the high beam. Literally, it means the driver doesn't need to manually shift gears; instead, the vehicle's computer automatically shifts gears based on road and driving conditions.

What is the best way to press the accelerator in an automatic transmission car?

Use the sole of your foot to feel the pressure when pressing the accelerator. The foot used for the accelerator is the right foot, and the entire sole should be placed on the accelerator. Some say women should not drive in high heels, which is correct. The most important point is that both men and women should avoid driving in thick-soled shoes. When starting the car, release the clutch and gently press the accelerator before reaching the critical point to give some fuel, making it less likely for the car to stall. Do not press the accelerator when going downhill. Keep your foot on the brake and be ready to brake at any time.

What is the simplest method for driving straight with an automatic transmission?

Before starting the car, adjust your seating position properly. An incorrect seating posture can affect visual judgment and easily lead to deviation. Look as far ahead as possible. During straight-line driving, keep your gaze focused far ahead. Many learners only notice the car deviating when it has already started to drift. Therefore, when driving straight, extend your line of sight and make minor adjustments as soon as the vehicle begins to deviate.
