Why Does a Dual-Clutch Have Three Pedals?

The reason a dual-clutch has three pedals is: dual-clutch vehicles have two clutch pedals and one accelerator pedal. The clutch is located between the engine and the transmission, serving as the switch for power transmission between the engine and the transmission. It is a transmission structure that can both transmit and cut off power. Precautions for using the clutch include: 1. The clutch must be thoroughly cleaned before installation to remove anti-rust grease and debris; 2. The clutch can be installed coaxially or on separate shafts, but axial fixation is mandatory; 3. For wet electromagnetic clutches, lubricating oil must be added between the friction plates during operation; 4. The power supply and control circuits must use a 24V DC power source for the clutch; 5. When installing a jaw-type electromagnetic clutch, ensure there is a certain gap between the end face teeth to prevent grinding during idling.

I used to drive dual-clutch cars frequently and noticed that all such vehicles have only two pedals: the brake and the accelerator. The dual-clutch transmission is automatic, with the computer controlling the two clutches, so the driver doesn’t need to press a third clutch pedal. Manual transmission cars have three pedals, such as the clutch, brake, and accelerator, because the driver needs to operate the gear shifts manually. The dual-clutch design aims to provide a smoother driving experience by eliminating the hassle of left-foot operation. It makes driving much easier in heavy city traffic, as you don’t have to constantly press the clutch. Some people might mistakenly think there are three pedals, perhaps influenced by manual transmissions or having tried paddle-shifted manual modes, but those aren’t pedals. With over a decade of driving experience, I recommend learning more about car types to avoid confusion.

How to Check Coolant Level?

Generally, the maximum level should not exceed the outer circular protrusion of the expansion tank, and the minimum level should not be lower than the marked "MIN" line. However, this minimum level is not an indication that the car cannot be used if the coolant is below this position; it is merely a warning sign. Below is relevant information about coolant: 1. Adding Coolant: Under normal circumstances, the car's coolant will not be depleted. Even in cars used for several years, the coolant level will only drop to the lower limit due to the evaporation of water in the coolant, but the antifreeze and cooling performance of the coolant will not decrease. Generally, as long as coolant is visible in the expansion tank, it means there is enough coolant and no need to add more. If addition is indeed necessary, do not exceed the upper limit, as the coolant may overflow when the engine temperature rises. 2. Replacing Coolant: Car coolants are colored, which serves as an indicator. For example, if this car's coolant is pink and the color becomes very faint, it indicates that the additives in the coolant are nearly depleted, and the coolant needs to be replaced. The same applies to coolants of other colors. When replacing, it is best to choose the same brand and model of coolant and have a professional mechanic perform the operation. System bleeding during replacement is crucial, as air in the system can cause the engine to overheat. 3. Function of the Radiator: The expansion tank filled with coolant plays a significant role in the proper functioning of the cooling system. Especially the radiator cap on top, which contains two valves: the steam valve and the intake valve. These valves maintain the correct pressure in the cooling system, raise the boiling point of the coolant, and prevent coolant loss. If an ordinary cap is used as a replacement, the engine may not only overheat, but the coolant may also deplete quickly.
