Should I use S gear or D gear for highway driving?

For highway driving, using D gear is sufficient. You can use S gear during aggressive driving or overtaking. Introduction to S gear: Most automatic transmissions have an S gear, where 'S' stands for 'Sport', meaning sports mode. When switched to S gear, the transmission enters sports mode, and the engine's operating mode will also change accordingly. In S gear, the transmission delays shifting, only upshifting when the engine speed reaches the redline zone. Reason for using D gear on highways: During highway cruising, such strong power and rapid power response are not necessary, so using D gear is adequate.

What are the reasons for rapid engine oil consumption?

High engine load, excessive crankcase pressure, and large crankcase exhaust gas flow can lead to insufficient oil-gas separation capability, resulting in rapid engine oil burning. Cylinder compression test: Steps such as checking whether the vehicle's power has decreased (power reduction indicates decreased compression ratio) can help determine if there's oil burning. This can be measured using traditional methods like performing a cylinder compression test (or adding some oil for comparative compression measurement). If the cylinder pressure is insufficient, it at least indicates poor piston ring sealing, and the severity of oil burning can also be inferred based on the cylinder pressure readings.

What to Do When There's Noise When the Window Is Fully Closed but Disappears When Opened?

Window is fully closed but there's noise that disappears when opened. The solution is: 1. Close all doors and operate each window one by one from the driver's seat to identify the glass causing the noise; 2. Raise the noisy window to the top, take out the prepared dashboard wax, and spray it evenly into the gap between the outer felt strip and the glass. Do not use too much, but ensure it is evenly applied. After spraying, raise and lower the noisy window two to three times consecutively, and the noise will either disappear or reduce. Car windows are the openings set in the four walls of the vehicle compartment. The front and rear windows of a car usually use curved glass that is both aesthetically pleasing and provides good visibility, embedded in the window frame with rubber sealing strips or adhered with special adhesives. To facilitate natural ventilation, the side windows of a car can usually be moved up and down or back and forth.

What Are the Consequences of Severe Engine Oil Burning in Cars?

Severe engine oil burning can lead to adverse consequences such as increased carbon deposits in the combustion chamber, unstable idling, weak acceleration, and excessive exhaust emissions. In severe cases, it may result in insufficient engine lubrication, causing irreparable damage to the engine or even rendering it unusable. Cold Engine Oil Burning: Park the vehicle overnight and observe the exhaust emissions during the first start in the morning. If the exhaust emits thick blue smoke, it indicates the presence of engine oil burning. If the blue smoke disappears after the engine warms up, this type of oil burning is classified as cold engine oil burning. Constant Oil Burning: If blue smoke is visible immediately upon starting the engine, the oil burning condition is already quite severe and may even pose a safety hazard. Acceleration-Induced Oil Burning: After the engine warms up, whether during rapid acceleration or idling, if blue smoke is emitted from the exhaust pipe whenever the RPM rises sharply, it indicates the presence of engine oil burning. Solutions for Engine Oil Burning: Promptly replace the valve stem seals to ensure the sealing of the valves; regularly clean carbon deposits on the piston rings or directly replace the piston rings; and maintain moderate driving habits during daily use to avoid overly aggressive driving.

Will points be deducted for crossing the diversion line when changing lanes?

Points will be deducted, specifically three points. The diversion line is a prohibited marking used to indicate that vehicles must drive along the designated route and are not allowed to cross or drive over the line. If a vehicle crosses or drives over the diversion line, the police can impose a penalty of "warning and deducting 3 points" on the driver. Here is more related information: Purpose of the diversion line: The purpose of the diversion line is to ensure that every vehicle "stays in its lane," serving to regulate, guide, and warn traffic, thereby reducing traffic accidents. Diversion lines are mainly used at intersections that are too wide, irregular, or have complex driving conditions, at the entrance of ramps for overpasses, or at other special locations. The form of the diversion line at intersections is usually one or several white V-shaped lines or diagonal striped areas set according to the terrain of the intersection, indicating that vehicles must bypass the diversion line as required, and are not allowed to cross or drive over the line, nor to make U-turns or park arbitrarily within the diversion line area.

Are locomotives the same as motorcycles?

Locomotives and motorcycles are not the same. Different licenses: Ordinary three-wheeled motorcycles require a D license, ordinary two-wheeled motorcycles require an E license, and light motorcycles require an F license. Motorcycles are categorized into three-wheeled motorcycles, ordinary two-wheeled motorcycles, and two-wheeled light motorcycles. Locomotives belong to two-wheeled motorcycles, and the nature is different, so the motorcycle driving license obtained is also different. Motorcycle driving licenses are divided into three-wheeled motorcycle D license, two-wheeled motorcycle E license, and two-wheeled light motorcycle F license. Categories of motorcycles: A three-wheeled motorcycle D license can not only drive three-wheeled motorcycles but also ordinary two-wheeled motorcycles and two-wheeled light motorcycles. Ordinary two-wheeled motorcycles are divided into scooters and straddle types. Both use the motorcycle E license, which only allows driving ordinary two-wheeled motorcycles and two-wheeled light motorcycles but not three-wheeled motorcycles. Light motorcycles use the F license, which only allows driving two-wheeled light motorcycles but not ordinary two-wheeled motorcycles or three-wheeled motorcycles. If the vehicle driven does not match the permitted vehicle type, it will result in a 12-point penalty.

What is the reason for the right side being too narrow during parallel parking?

This is because the second left turn of the steering wheel was slightly delayed. From the car's position in the garage, being particularly close to the right side means that the rear of the car may hit the boundary line of the garage during the parking process. If the operation was entirely according to the instructor's teaching process, then the issue might be that the seat and rearview mirrors were not adjusted when getting into the car. Readjust the seat and rearview mirrors to positions that suit you, and then proceed with the operation. Method for parallel parking: During parallel parking, when there are no reference poles, learn to use the rearview mirrors to identify the marking lines. When the left front corner of the garage disappears from the right rearview mirror, turn the steering wheel to the right to the limit and continue reversing. While reversing, watch the left rearview mirror. When the bottom line of the garage is completely visible, straighten the steering wheel, continue reversing the car, and keep watching the left rearview mirror. When the left rear wheel is about to press the left boundary line of the garage, continue turning the steering wheel to the left to the limit, then normally turn on the turn signal and drive out of the yellow frame marking line.
