What are the advantages and disadvantages of dry and wet dual-clutch transmissions?

Dry dual-clutch and wet dual-clutch transmissions share similarities but also have differences. Neither is inherently superior to the other, as each has its own strengths and weaknesses. Below is a comparison of their advantages and disadvantages: 1. Dry-type has inferior heat dissipation compared to wet-type: Due to poorer heat dissipation, dry dual-clutch transmissions face higher risks of clutch plate overheating or even burning in congested urban areas. In this aspect, wet dual-clutch transmissions demonstrate higher technological maturity. 2. Dry-type offers higher power transmission efficiency: Wet dual-clutch transmissions rely on hydraulic fluid. The wet-type clutch plates are immersed in transmission fluid, which provides better heat dissipation. From the perspective of technological maturity and reliability, wet dual-clutch transmissions are more stable in operation since the clutch plates work in hydraulic oil that aids in cooling. However, wet dual-clutch transmissions have more complex structures, higher manufacturing costs, and slightly lower power transmission efficiency compared to dry-type. Additional information: Dual-clutch transmissions are categorized into dry and wet types. Both types operate on fundamentally similar principles, featuring two clutches that alternate in operation.

What is the fuel tank capacity of the 2017 Corolla in liters?

The Corolla has a total of 12 models currently on sale. Among them, the 1.8L displacement models have a fuel tank capacity of 43 liters, while the remaining models have a fuel tank capacity of 50 liters. This data is officially released, and Corolla owners can also check it on their vehicle's configuration sheet. The Corolla uses 92-octane fuel. The 1.8L displacement models have a fuel consumption of 4 to 4.1L per 100 kilometers, allowing a full tank to cover a distance of 1049 to 1075km. The other models consume 5.1 to 5.6L per 100 kilometers, enabling a full tank to travel between 8929 to 9804km. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically observed through the fuel gauge inside the vehicle. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it is advisable to refuel when only 2 segments remain to avoid running out of fuel midway. During actual refueling, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safe fill level. There is additional space from the safe fill level to the tank opening, designed to accommodate fuel expansion due to temperature increases without causing overflow. If fuel is filled up to the tank opening during refueling, the actual fuel volume may exceed the calibrated tank capacity.

Where is the fuel tank cap switch of Borgward BX5 located?

Borgward BX5's fuel tank cap switch is located on the right side of the vehicle body, and the fuel tank cap can be opened by pressing it. Common methods to open the fuel tank cap: 1. Mechanical key method: This type of fuel tank cap switch is relatively rare, usually found on some hardcore off-road vehicles. Nowadays, family cars do not use mechanical keys to open the fuel tank cap because it is relatively complicated to use. 2. In-car switch method: The in-car switch is currently the most common way to open the fuel tank door, which is certainly more convenient compared to using a key. The in-car switch is located in different positions in different car models, some are on the floor to the left of the driver's seat, some are on the left front door panel or the center console, all marked with a fuel pump icon. However, it should be noted that the in-car switch can easily make the owner forget to turn off the engine before refueling, so the owner should remember to turn off the engine before refueling. 3. Press-to-open method: The press-to-open fuel tank door is currently the most convenient method. The owner only needs to park the car, and the gas station attendant can directly refuel. However, when the owner is not parking to refuel, remember to lock the central control, otherwise the fuel tank cap can be opened.

What Causes the Engine Warning Light to Illuminate in the Avalon?

The engine warning light in the Avalon may illuminate due to the following 7 main reasons: Sensor malfunction: Sensors such as coolant temperature, crankshaft position, air flow, intake temperature, and oxygen sensors may become damaged, have poor connections, or experience signal interruptions. When the car's ECU cannot accurately obtain engine data, the engine warning light will illuminate. Fuel or oil quality issues: If fuel or engine oil is not added according to the manufacturer's requirements, it may cause engine wear, leading to the warning light turning on. Poor combustion of the air-fuel mixture: Poor combustion can cause engine carbon buildup or knocking. When detected by the oxygen sensor and reported to the ECU, the warning light will illuminate as a warning. Issues such as faulty spark plugs, ignition coils, fuel pumps, or clogged fuel lines can all lead to poor combustion. Turbocharger issues: Problems with the intake boost pipes or turbocharger can also trigger the engine warning light. The most common issue is a damaged turbocharger, accompanied by symptoms like oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake issues: If the car's intake system is compromised, it may lead to clogged engine pipes, and in severe cases, the engine warning light will illuminate. A dirty or uncleaned air filter can cause intake problems. Exhaust issues: Exhaust system faults can also trigger the engine warning light. Common causes include faulty rear oxygen sensors, catalytic converters, exhaust camshafts, or bearings. The catalytic converter is the most frequent culprit, often damaged by leaded gasoline, lead/silicon-based lubricant additives, physical impacts, or fuel system malfunctions. Anti-theft system malfunction: If the car's electronic anti-theft system fails or the anti-theft controller does not match the engine ECU, the anti-theft system may prevent the engine from operating normally, and the warning light will illuminate. If the engine warning light is on, follow these steps: First, check if the engine is running normally, such as whether there is shaking or black smoke. If so, avoid restarting the engine. Note: Do not restart the engine if the red warning light is on. If the engine can start, turn it off and wait 5-10 minutes. Without pressing the brake, press the start button once or turn the key halfway to the "ON" position (without pressing the clutch). The car will enter self-check mode. After 5-10 seconds, observe whether the warning light turns off. If the light remains on, visit a service center as soon as possible. Technicians can use a diagnostic tool to read the fault code and perform targeted repairs.

How to Understand the Combination of Automatic Transmission DS?

DS gears are placed together for the convenience of the driver during vehicle operation. The D gear is the forward drive gear, while the S gear is the sport mode. Placing these two gears together provides convenience for the driver. Normally, the D gear is used, while the S gear is employed when experiencing sporty sensations like instant acceleration, and switching between them can be done directly. The letters P, R, N, D, S, L on the car gearshift represent the following meanings: 1. "P" on the gearshift: Stands for Parking, which is the parking gear. Engaging this gear utilizes the vehicle's auxiliary braking system to park the car. It is important to note that after parking, it is best to engage the P gear to prevent excessive wear on the transmission. 2. "R" on the gearshift: Stands for Reverse, which is the reverse gear. When the vehicle needs to reverse, only by engaging this gear can the car move backward, but it should only be engaged after the vehicle has come to a complete stop. 3. "N" on the gearshift: Stands for Neutral, which is the neutral gear. When the vehicle is in neutral, it disconnects the power system between the engine and the transmission. It is not recommended to coast in neutral when going downhill, as it poses certain safety risks. 4. "D" on the gearshift: Stands for Drive, which is the forward drive gear. This gear is undoubtedly the most frequently used, especially in automatic transmission models, where "D gear for all driving" is a preferred mode for many drivers. 5. "S" on the gearshift: Stands for Sport, which is the sport gear. This gear is often used when climbing hills to provide additional power, though it increases fuel consumption. 6. "L" on the gearshift: Stands for Low, which is the low-speed gear. This gear is mainly used when descending hills or long slopes, keeping the gear in the lowest position to utilize engine braking for safer downhill driving. Maintaining high RPMs for extended periods enhances vehicle power.
