Differences Between Dry and Wet Dual-Clutch Transmissions

Dry and wet dual-clutch transmissions differ in the following aspects: 1. Cooling Methods: Dry dual-clutch transmissions rely on air cooling for heat dissipation; Wet dual-clutch transmissions are immersed in oil, offering higher cooling efficiency. 2. Operational Differences: Dry clutches use manual transmission friction plates, featuring high mechanical transmission efficiency but more complex operation and higher failure rates; Wet clutches employ automatic transmission oil-immersed friction plates, with lower mechanical transmission efficiency but easier operation and lower failure rates. Dual-clutch transmissions are not suitable for frequent starts, prolonged low-speed driving, or stop-and-go traffic conditions, as they are prone to overheating, which can lead to malfunctions. Once the vehicle's computer issues a warning, it is essential to stop immediately to cool down the transmission.

Can You Still Drive with Worn Brake Pads?

It is possible to drive with worn brake pads, but they should be replaced as soon as possible. Safe driving distance after detecting brake pad wear: After the Mercedes dashboard indicates that the brake pads are worn, the safe driving distance is 100 kilometers, and all brake pads will wear out within 1,000 kilometers. Brake pads are one of the most critical safety components of a car, directly related to the vehicle's braking performance. Structural components of brake pads: The key structural components of brake pads include: steel plate, bonded heat insulation layer, and friction block. The main materials of the friction block are friction material and adhesive. In terms of brake pad types, they can be classified based on application and production materials. Since brake pads are crucial, they should be well-maintained.

What Causes Poor Acceleration in First and Second Gear of a Car?

Poor acceleration in first and second gear of a car is related to carbon buildup and poor fuel quality. Carbon Buildup Issue: There are three main reasons for poor car acceleration. The first is carbon buildup on components such as the valves, idle air control valve, intake manifold, combustion chamber, and spark plugs. This can cause the engine to stall when the car is idling. Poor Fuel Quality: One of the most significant causes of poor car acceleration, and a common issue in many cases, is the use of low-quality fuel. This can affect the gasoline filter and fuel lines, potentially leading to insufficient fuel supply and resulting in poor acceleration. Additionally, it can impact the lifespan of the exhaust system's catalytic converter. If the catalytic converter becomes clogged, it will directly affect the vehicle's acceleration performance and also increase fuel consumption, contributing to the phenomenon of poor acceleration.

How often should I change the oil if I don't drive much?

If you don't drive much, you should change the oil every six to eight months, as the oil can oxidize and deteriorate when left in the engine oil pan for extended periods. The functions of engine oil are: 1. To separate the surfaces of relatively sliding parts and reduce wear; 2. To carry heat back to the oil tank and then dissipate it into the air, helping the radiator cool the engine; 3. To circulate carbon deposits, sludge, and wear particles from engine parts back to the oil tank, flushing away dirt generated on the working surfaces of the parts through the flow of the lubricating oil. The method for changing the oil is: 1. Lift the vehicle with a jack; 2. Drain the old oil; 3. Remove the oil filter; 4. Install a new oil filter and refill with new oil.

At what level of tire wear must replacement occur?

When tire wear reaches 1.6mm, replacement is mandatory. Factors related to wear level: Tire tread wear level - new tires typically have a thickness of around 8mm. When wear reduces this to approximately 1.6mm, the tire should be replaced. The rate of wear is directly influenced by mileage and driving habits. The normal lifespan ranges between 50,000 to 80,000 kilometers. Upon reaching this mileage, regular checks of tire thickness should be considered. Tread aging degree: Tire aging significantly depends on usage duration and environmental conditions, with a standard service life of about 6 years. Harsh environments can accelerate this timeline. Aged tires will exhibit numerous surface cracks. If such signs are observed, immediate replacement is advised even before reaching 6 years, as delayed action may lead to severe blowout risks.
