What is the function of bearing bush?

Between the small end of the connecting rod and the piston pin. The main function of the bearing bush is to provide friction protection for the connecting rod or crankshaft during high-speed operation. During engine operation, incidents of bearing seizure and shaft burning occasionally occur, mostly caused by improper bearing bush installation. Bearing seizure and burning mainly result from the rupture of the lubricating oil film between the journal and the bearing bush, leading to friction between the bearing bush and the crankshaft. Relevant introductions about the bearing bush are as follows: 1. Introduction one: In steam turbines, the bearing bush is one of the important components of the bearing, being the part of the sliding bearing that contacts the shaft. It is very smooth and usually made of wear-resistant materials such as bronze or anti-friction alloys, also known as "bushings," shaped like a semi-cylindrical tile. 2. Introduction two: Its main functions are to bear the force applied by the journal, maintain stable oil film, ensure smooth bearing operation, and reduce bearing friction loss. Bearing bushes are divided into axial thrust bushes and radial bushes. Radial bushes support the rotor and rotating parts, while thrust bushes handle axial positioning and axial thrust, serving as important stationary components.

Why can the doors of the BMW X1 still be opened after automatic locking?

The BMW X1 doors can still be opened after automatic locking, which is a specially designed feature by BMW. This is to prevent situations where, in the unfortunate event of an accident, people inside the car are unable to open the doors, and those outside cannot open them either, delaying rescue efforts. With the ability to open doors after automatic locking, there is no need to worry about rescue delays. More information about the BMW X1 is as follows: 1. The car's interior adopts a spliced design that is more fashionable, with a bright panel design embedded on the upper side of the center console for a more youthful look, and the inlaid silver chrome trim adds a decorative effect. 2. The new car offers two power options: 1.5T and 2.0T, with the Ministry of Industry and Information Technology reporting power outputs of 155 horsepower for the 1.5T model and 214 horsepower for the 2.0T model.

Is it allowed to reverse when driving in the wrong lane?

No, it will result in a deduction of 3 points. Reversing constitutes a violation of the prohibition signs by motor vehicles, and the penalty is a 3-point deduction from the driver's license and a fine. The following are the relevant laws and regulations: The "Road Traffic Safety Law of the People's Republic of China" stipulates: Article 90: If a motor vehicle driver commits any of the following illegal acts, 3 points shall be deducted at one time: If a motor vehicle driver violates the road traffic safety laws and regulations regarding road traffic regulations, they shall be given a warning or fined. If there are other provisions in this law, the punishment shall be imposed in accordance with the provisions. If a motor vehicle driver commits any of the following illegal acts, 3 points shall be deducted at one time: 1. Violating traffic signal lights; 2. Driving on a highway below the minimum speed limit; 3. Driving a motor vehicle on the road without displaying the vehicle license plate; 4. Intentionally covering, damaging, or not installing the vehicle license plate as required; 5. Driving in the opposite direction.

How to Make Car USB Charging Faster?

Car charging can be slow and may not quickly recharge your phone. For faster charging, it's better to use a socket and plug. Here are more related details: 1. Reason: The interface on the car CD player is for data use, not for charging. Moreover, its output is only 500mA. When charging a phone, the charger's output capability is crucial. If the maximum output is only 500mA, the charging current cannot exceed 500mA. Therefore, it can only maintain the phone's battery level but cannot charge it effectively, and it may even damage the phone. 2. Precautions for charging your phone with a car USB: Ensure that the output current of the car charger is not less than the phone's maximum rated input power. For example, a car charger with an output of 5V/2.1A can provide 1A to a phone with a maximum rated input power of 5V/1A and 2A to a tablet, allowing for faster charging. Conversely, not only will charging be slower, but the phone may also overheat significantly, potentially damaging the battery over time.

What does vehicle width mean?

Vehicle width refers to the distance between two planes parallel to the longitudinal symmetry plane of the vehicle, which respectively abut against the fixed protruding parts on both sides of the vehicle (excluding rearview mirrors, side marker lights, turn signal indicators, flexible mudguards, and the deformation of the part where the tire contacts the ground). Below is an introduction to related car dimensions: 1. Definition: Car dimensions refer to the regulations limiting the total height, total width, and total length of a vehicle. 2. Vehicle length: The distance between two vertical lines perpendicular to the longitudinal symmetry plane of the vehicle, which respectively abut against the outermost protruding parts at the front and rear of the vehicle. 3. Wheelbase: The distance between two vertical lines of the vehicle's longitudinal symmetry plane when the vehicle is in a straight driving position, measured from the ground contact center points of the wheels on the same side of adjacent axles. 4. Track width: On the supporting plane, the distance between the center lines of the left and right wheel tracks on the same axle (for dual wheels at both ends of the axle, it is the distance between the center lines of the left and right dual tracks).

What do D1, D2, and D3 mean in an automatic transmission?

D1, D2, and D3 in an automatic transmission are all gear restrictions. Using these restricted gears locks the vehicle in a fixed forward gear without upshifting or downshifting, preventing the transmission from jumping to a higher gear. D1, D2, and D3 can be switched while driving, but it's important to note that shifting from high speed to low gear will cause noticeable engine braking, and the brake lights won't illuminate during this deceleration, which could lead to misjudgment by following vehicles. The correct usage of D1, D2, and D3 is as follows: 1. D1: Similar to gears 1-2 in a manual transmission, it has the highest gear ratio and strongest torque output, making it suitable for steep climbs or towing other vehicles. 2. D2: Similar to gears 3-4 in a manual transmission, with a reduced gear ratio and torque output, it is also suitable for climbing or towing. 3. D3: Similar to gears 5-6 in a manual transmission, it offers balanced torque and power output. Engaging it directly while driving can downshift to provide high torque for overtaking, with the advantage of minimal noticeable jerking and quicker throttle response.
