Which is Better: Dry Dual Clutch or Wet Dual Clutch?

Wet dual clutch is better than dry dual clutch, but it is also more expensive. Wet dual clutch refers to a multi-plate clutch system where two sets of clutches, one large and one small, are coaxially installed together. They are housed in a sealed oil chamber filled with hydraulic fluid, giving the wet clutch structure better adjustment capabilities and superior thermal properties. It can transmit larger torque without damage. However, due to layout and friction material selection factors, the overall size of a wet dual clutch is larger than that of a dry dual clutch. Below is a detailed comparison between wet dual clutch and dry dual clutch: 1. Differences: The key difference between wet and dry dual clutches lies in the working environment of their clutch plates. In a wet dual clutch, the clutch plates are immersed in transmission fluid, whereas in a dry dual clutch, the plates directly contact the engine flywheel. From a perspective of technical maturity and reliability, wet dual clutches are more stable because the hydraulic fluid helps dissipate heat from the clutch plates. Dry dual clutches, on the other hand, suffer from poor heat dissipation, making them prone to overheating or even burning in congested urban driving conditions. In this regard, wet dual clutch transmissions are more mature in technology. However, wet dual clutches are more complex in structure, have higher manufacturing costs, and their power transmission efficiency is lower than that of dry dual clutches. 2. Advantages: Wet dual clutches are stable and mature, capable of achieving fast and smooth gear shifts without interruption. Additionally, the fluid helps dissipate heat at low speeds, preventing overheating. 3. Disadvantages: Naturally, due to their complex structure, wet dual clutches are larger and heavier, with significantly higher manufacturing costs compared to dry dual clutches. They also require more time and effort to maintain and need regular cooling fluid replacements.

Should You Shift to Neutral at Red Lights with an Automatic Transmission?

Automatic transmission cars should be shifted to neutral when waiting at red lights. Here is an introduction to gear shifting knowledge for automatic transmission cars: 1. Practice at red lights: The correct approach when waiting at red lights with an automatic transmission is to use 'Neutral gear + handbrake.' This method does not harm the car, as the Neutral gear disconnects the engine from the transmission's power transfer, and the handbrake prevents situations like rolling collisions. 2. Auto Start-Stop function: After activating this function by pressing the button, the vehicle will automatically brake once it comes to a stop, eliminating the need to shift from reverse or drive gears, keeping the vehicle in a parked state. However, not shifting into neutral still poses certain safety risks, such as rapid acceleration if the accelerator is accidentally pressed, which can easily lead to collision accidents.

What is the speed limit for each lane in a three-lane same-direction highway?

On a same-direction three-lane highway, the minimum speed for the leftmost lane is 110 kilometers per hour, the middle lane is 90 kilometers per hour, and the rightmost lane is 60 kilometers per hour. Below is relevant information about highway driving: 1. Speed limits for different vehicles: The maximum speed for small passenger vehicles on highways should not exceed 120 kilometers per hour, other motor vehicles should not exceed 100 kilometers per hour, and motorcycles should not exceed 80 kilometers per hour. 2. Speed limits for different lanes: If there are two lanes in the same direction, the minimum speed for the left lane is 100 kilometers per hour; if there are three or more lanes in the same direction, the minimum speed for the leftmost lane is 110 kilometers per hour, and the middle lane is 90 kilometers per hour. If the speed limit indicated by road signs differs from the above lane speed regulations, drivers should follow the speed limit indicated by the road signs.

Can a new car be driven on the road without a temporary license plate?

No, a new car must have a license plate to be driven on the road. Without a temporary license plate, it cannot be driven. Below are specific details about temporary license plates: 1. Validity period: Temporary license plates must be used within their validity period. Using them beyond this period will result in penalties. 2. Placement: Temporary license plates must be affixed to the windshield. For passenger vehicles that have not yet been registered and need to be driven temporarily, two temporary license plates must be affixed—one on the lower left or right corner of the front windshield where it does not obstruct the driver's view, and the other on the lower left corner of the rear windshield. 3. Usage regulations: Temporary license plates are applicable for vehicles obtained through purchase, allocation, gifting, etc., that have not yet been registered.

What's the reason for occasional abnormal noise when stepping on the clutch?

Analysis of the reasons for occasional abnormal noise when stepping on the clutch: 1. Lightly stepping on the clutch pedal, there is an obvious "rustling" sound: It can be judged that the clutch release bearing is making noise. In this case, you can apply grease to the release bearing. If the noise persists after applying grease, it means the release bearing is damaged, such as if the bearing is stuck or has excessive axial clearance, and a new bearing should be replaced. If the inner ring of the bearing is worn by more than 0.3mm, causing the entire bearing to rotate idly on the release sleeve, both the bearing and the release sleeve should be replaced. 2. Stepping on the clutch pedal produces a "clanging" metal friction sound: Remove the flywheel housing for inspection. If you see signs of burning or sparks at the contact point between the clutch release bearing and the release lever, it indicates that the clutch release bearing is not rotating or is damaged, and the bearing should be replaced. 3. When the engine is idling, there is a "clattering" sound from the clutch, and slightly pressing the accelerator: If the noise does not change, it may be caused by a broken release lever screw, and the damaged part should be replaced. 4. When the engine is idling, there is a "thudding" impact sound from the clutch: If the noise weakens or disappears at medium speed or above, and also disappears when the clutch pedal is pressed again, it indicates that the rivets of the clutch friction plate are loose or the keyway of the driven plate hub is worn. In this case, you can remove the bottom cover of the flywheel housing (or clutch chamber), turn off the engine, engage the transmission, press the clutch pedal, and use a screwdriver to check the keyway of the driven plate for clearance. If the clearance is large, repair or replace the part. 5. If there is noise or intermittent knocking when the clutch pedal is fully released: The reason may be that there is no clearance between the clutch release bearing and the release lever. In this case, adjust the free travel of the clutch pedal, i.e., the clearance between the release bearing and the release lever. It may also be due to a weak, broken, elongated, or fallen return spring, causing the release bearing to slide freely and make noise when contacting the release lever. Repair or replace as needed.
