What is the Principle of a Dual-Clutch Transmission?

1 Answers

StEmily

07/29/25 1:16pm

The key technology of a dual-clutch transmission lies in its dual-clutch system, which consists of two clutches. One clutch is responsible for the odd-numbered gears (1st, 3rd, 5th, and 7th), while the other handles the even-numbered gears (2nd, 4th, and 6th). Below is a detailed introduction: 1. Dual-Clutch Transmission (DCT): Unlike conventional automatic transmission systems, a DCT is based on a manual transmission but operates as an automatic. It combines the flexibility of a manual transmission with the comfort of an automatic, while also providing uninterrupted power output. 2. Technical Advantages: The gear-shifting time of a DCT is extremely short—faster than that of a manual transmission, taking less than 0.2 seconds. By eliminating torque interruption, the DCT ensures that the engine's power is continuously utilized and always operates at its optimal efficiency, resulting in significant fuel savings.

What causes unstable idle speed within seconds after starting the car?

Detailed explanation and solutions for unstable idle speed immediately after starting the car are as follows: 1. Excessive engine carbon deposits: When there is too much carbon buildup inside the engine, the fuel injected by the injectors during startup will be largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture. This makes starting difficult and causes idle speed fluctuations during startup. Solution: Perform carbon cleaning. 2. Overused air filter: If the air filter is not replaced in time, it can cause insufficient air intake, lowering the engine idle speed and leading to engine vibration. Solution: Replace the air filter. 3. Low ignition energy: During a cold start, the internal temperature of the engine is insufficient, requiring the injectors to spray more fuel to meet power demands. The fuel needs higher ignition energy, but increased spark plug gap can reduce ignition energy, affecting performance and causing vehicle vibration. Solution: Warm up the vehicle.

Why is Toyota's TNGA Architecture Safer?

Here are the reasons why Toyota's TNGA architecture is safer: 1. Globally synchronized safety standards. Vehicles under the TNGA architecture adhere to stringent safety performance standards, capable of withstanding authoritative crash tests both domestically and internationally, without differentiation—consistent across all markets. 2. Standard safety features across all models. Unlike other brands where safety features vary significantly between high and low trim levels, TNGA architecture ensures that vehicles of all levels come equipped with a large number of higher-class safety features as standard. 3. Comprehensive protection safety standards. TNGA's safety standards are not limited to certain occupants but extend to all, including the driver, passengers inside the vehicle, and pedestrians outside. In the C-IASI tests, several GAC Toyota TNGA models achieved "GOOD" ratings in occupant safety and pedestrian protection indices.

Why does the Audi Q5 auto start-stop fail after maintenance?

Audi Q5 auto start-stop failure reasons are as follows: Accidentally pressing the auto start-stop button: Vehicles equipped with auto start-stop function usually have the system enabled by default. If it suddenly stops working, it might be due to accidentally pressing the auto start-stop button, which turns off the system. Check if the system has been disabled; Start conditions not met: If the car is a manual transmission, the conditions for auto start-stop are more complex. The system will only activate when it detects the following three actions after stopping: "shift to neutral, pull the handbrake, and release the clutch"; Temperature not reached: The function will not activate under the following conditions: the engine has not reached normal operating temperature, the automatic air conditioning has not reached the preset temperature, the battery charge is insufficient, the steering wheel is turned after stopping, the vehicle is in emergency braking, or reversing.

Is it harmful to the car to turn the steering wheel while stepping on the brake in place?

Turning the steering wheel while stepping on the brake in place can cause damage to the car's tires and power steering structure. The details are as follows: 1. Accelerated tire wear: When turning the steering wheel in place, the wheels roll in a circular motion with the steering knuckle axis as the center, which hinders the rolling of the wheels, resulting in friction sounds between the wheels and the ground. It also creates a relative motion trend between the friction blocks and the brake discs. Frequent turning of the steering wheel in place will accelerate the wear of the front tires, increasing driving safety risks. 2. Damage to the power steering mechanism: Frequent turning of the steering wheel in place can damage the power steering mechanism, increasing its workload and accelerating its aging and wear.
