How often should the dual-clutch transmission fluid be changed?

Dual-clutch transmission fluid should be changed every 60,000 kilometers. There are two types of dual-clutch transmissions: 1. Dry dual-clutch. The clutch plates of a dry dual-clutch transmission are not immersed in transmission fluid. 2. Wet dual-clutch. The clutch plates of a wet dual-clutch transmission are immersed in transmission fluid. The reliability and stability of wet dual-clutch transmissions are generally better than those of dry dual-clutch transmissions. Wet dual-clutch transmissions can handle greater torque and have better heat dissipation performance. Additional information: The shifting speed of dry dual-clutch transmissions is faster than that of wet dual-clutch transmissions.

What brand is the Xuan Yi transmission?

The Nissan Xuan Yi uses the XTRONIC CVT continuously variable transmission, model Jatco-JF015E, paired with a 1.6L naturally aspirated engine that meets the China VI emission standards, delivering a maximum power of 99kW (135 horsepower) and a peak torque of 159Nm. Introduction to the five major types of transmissions: 1. MT manual transmission, the full English name is manual-transmission, meaning manual gearbox, also known as manual shift. 2. AT automatic transmission, the full English name is automatic-transmission. The automatic transmission consists of a torque converter, planetary gears, and a hydraulic control system, achieving speed and torque changes through hydraulic power transmission and gear combinations. 3. AMT automated mechanical transmission, the full English name is automated-mechanical-transmission, meaning mechanical automatic transmission. AMT can be seen as an automated manual transmission. The AMT transmission is equipped with an electronically controlled hydraulic system on a conventional manual transmission and clutch to achieve automatic gear shifting. 4. DCT dual-clutch transmission, the full English name is double-clutch-transmission, meaning dual-clutch transmission. 5. CVT continuously variable transmission, the full English name is Continuous-Variable-Transmission, meaning 'mechanical continuously variable transmission'.

Do Spark Plugs Affect the Engine?

Spark plugs have an impact on fuel consumption. If a spark plug is damaged, it can cause the engine to lose power, idle unstably, and most importantly, make ignition difficult, affecting the normal use of the vehicle. Methods to determine if a spark plug is damaged: Remove the spark plug and observe its appearance to assess its condition. A normal spark plug's insulator skirt and electrodes should appear gray-white, gray-yellow, or light brown. A properly functioning spark plug will have a reddish-brown insulator skirt, with an electrode gap between 0.8-0.9mm and no signs of electrode burn. If the spark plug has oil stains or deposits but is not damaged, it can continue to be used after cleaning off the oil and deposits. If the spark plug is severely damaged—showing signs of blistering, black streaks, cracks, or melted electrodes—identify the cause of the damage, troubleshoot the issue, and replace the spark plug. Additionally, if the spark plug appears black as if smoked, it indicates the wrong heat range was selected or the air-fuel mixture is too rich, possibly due to oil leakage. Steps for replacing spark plugs: Open the hood, lift the engine's plastic cover, and remove the high-voltage wires. Mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for external debris like leaves or dust and clean thoroughly. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the high-voltage wires in the firing order and secure the cover.

What does 'Pointed-Ear BMW' mean?

Pointed-Ear BMW refers to the BMW M series. Here is some relevant information: 1. It differs from the standard version in terms of the rearview mirrors. The M series rearview mirrors feature a more prominent pointed tip, which is an extremely refined aerodynamic design. In fact, M is also a specialized division within the BMW Group. Beyond designing and manufacturing the M series high-performance vehicles, BMW M's operations include BMW Individual (BMW's personalized customization service), a special department that caters to customers' extreme personalized needs. 2. Additionally, the BMW M division offers specialized driving training. The BMW M series models include: BMW M8, M6, M3, M2, M5, M4, BMW X6 M, BMW X5 M, among others. The BMW X5 and X6 are both positioned as mid-to-large-size SUVs. The BMW X6 M model is equipped with a 4.4T V8 turbocharged engine, delivering a maximum power of 575 horsepower and a peak torque of 750 Nm, paired with an all-wheel-drive system, achieving 0-100km/h acceleration in just 4.2 seconds.

What is the difference between 5W-30 and 5W-40 engine oil?

5W-30 and 5W-40 engine oils mainly differ in the following aspects: 1. 5W-40 oil provides better protection for the engine under high-temperature conditions compared to 5W-30. 2. 5W-40 has slightly higher viscosity than 5W-30. Due to its greater viscosity, the resistance to crankshaft rotation increases, making 5W-40 less fuel-efficient. Additional information: 1. Both 5W-30 and 5W-40 are SAE standard viscosity grades for engine oil. The first number indicates the lowest temperature at which the oil can be used. 2. The second number represents the kinematic viscosity of the oil at 100°C. A higher number indicates greater viscosity, better protective performance under high temperatures, and improved stability in high-temperature conditions.

Should the Steering Wheel Be Straightened After Parking the Car?

After parking the car, the steering wheel should be straightened. If not, it can have the following impacts: 1. Damage to the steering system. If the steering wheel is not straightened when parking, the wheels will pull the steering tie rod, preventing it from returning to its original position. At the same time, the steering wheel's gears and the tie rod's rack will remain under stress. Over time, this can accelerate aging or deformation, leading to vehicle misalignment and uneven tire wear. 2. Damage to the suspension system. When the steering wheel is not straightened, many car models' wheels will develop an angle, causing the suspension system to tilt in one direction. This places stress on components like the elastic struts, rubber seals, and rubber damping pads in the suspension system, preventing them from returning to their normal positions. This can lead to accelerated aging of the suspension's damping rubber, and excessive play in the connection points of the suspension's control arms and links, creating a vicious cycle of increasing wear. 3. Damage to the tires. When the steering wheel is not straightened, due to the kingpin inclination angle and the design of passenger car tire camber, the tire does not rest entirely on the tread but instead bears force on the shoulder and part of the tread. This puts significant pressure on the tire's sidewalls. Since the sidewalls are relatively thin, frequent unbalanced stress can accelerate their aging and deformation, potentially leading to air leaks or blowouts.
