What is the purpose of a dual-clutch transmission?

Dual-clutch function: Since there is no torque converter as part of the transmission system, its efficiency is similar to that of a manual transmission. When paired with appropriate shift logic, it can even achieve better fuel economy than a manual transmission. Essentially, it combines two manual transmissions, making it easier to produce and more cost-effective than traditional automatic transmissions. Its shift speed is second only to sequential and manual transmissions, with some models even outperforming manual transmissions in speed. Dual-clutch: A dual-clutch transmission differs from conventional automatic transmission systems. Based on manual transmissions yet belonging to the automatic transmission category, it is a transmission mechanism capable of both transmitting and cutting off power. Its primary functions are to ensure smooth vehicle starts, reduce the impact load on transmission gears during shifts, and prevent drivetrain overload. Drawbacks of traditional manual transmissions: Traditional manual transmissions use a single clutch. During gear shifts, the driver must depress the clutch pedal to engage different gears, resulting in a power interruption that causes intermittent output performance.

What Causes High Engine RPM Without Corresponding Speed Increase?

The reasons for high engine RPM without corresponding speed increase are: 1. Worn clutch plates; 2. Insufficient pressure torque on friction plate clutch; 3. Transmission fluid not changed for too long or damaged hydraulic mechanism in transmission; 4. Slipping internal friction plates in transmission; 5. Malfunction in engine electronic control system. Automotive RPM refers to the rotational speed of a car's engine. The tachometer is located on the instrument panel, symmetrically placed with the speedometer, and its functions are: 1. To promptly reflect the engine's operating condition; 2. To help drivers better coordinate transmission gear positions and throttle positions; 3. To maintain the vehicle in optimal working condition; 4. To reduce consumption and prolong engine lifespan.

Are There Any Disadvantages to Installing a Tire Pressure Monitoring System?

Installing a tire pressure monitoring system has no disadvantages. The system automatically and continuously monitors the tire pressure while the vehicle is in motion, and its functions include: 1. Providing timely alerts when there are signs of danger in the tires, prompting the driver to take appropriate measures to avoid serious accidents; 2. Ensuring the tires operate within the specified pressure and temperature range, reducing tire damage and extending their service life; 3. Minimizing wear on the suspension system. Methods to check tire pressure monitoring data include: 1. Using a tire pressure monitor; 2. Detecting tire pressure changes via navigation; 3. Pressing the tire pressure monitoring button on the central console area to view the data.

What does 15w40 engine oil mean?

15w40 engine oil refers to the viscosity grade of the oil, where 15 represents the lowest temperature at which the oil can be used in winter, which is -20 degrees Celsius. The smaller the number before the 'w', the lower the viscosity at low temperatures, the better the low-temperature fluidity, and the lower the applicable minimum temperature. The number 40 represents the kinematic viscosity in summer, meaning the higher the number after the 'w', the higher the applicable maximum temperature. The functions of engine oil include: 1. Reducing friction and high temperatures; 2. Cooling and temperature reduction; 3. Cleaning and purifying; 4. Shock absorption and cushioning; 5. Rust and corrosion prevention. Engine oil, also known as motor lubricant, is composed of base oil and additives. The base oil is the main component of the lubricant, determining its basic properties, while additives can compensate for and improve the shortcomings of the base oil's performance.

What to Do When the Engine Stalls Due to Water Ingress While Driving?

The methods to handle engine stalling caused by water ingress while driving are: 1. Do not attempt to restart the engine; push the vehicle to a location that does not obstruct traffic; 2. Close all doors and windows and wait for rescue. The impacts of a car driving through water include: 1. The engine may experience insufficient power and shaking issues; 2. Moisture or water ingress in the high-voltage distribution system causing short circuits; 3. Water entering the exhaust pipe; 4. Residual water can prevent the brake discs and brake pads from fully engaging, leading to loss of braking power; 5. Debris easily adheres to the gaps in the chassis, causing rust; 6. Water vapor forms inside the headlights, affecting light transmission; 7. Wet wiring harnesses and circuit interfaces in the engine compartment leading to short circuits.
