Is DCT an Automatic Transmission?

2 Answers

DCT stands for Dual-Clutch Transmission, which is a type of automatic transmission. The term 'dual-clutch' refers to the dual-clutch transmission system, which essentially means there are two sets of clutches working simultaneously—one managing the odd-numbered gears and the other managing the even-numbered gears. This design aims to eliminate the power interruption issue during gear shifts in traditional manual transmissions, thereby achieving faster gear changes. Below is an introduction to dual-clutch transmissions: 1. Origin: Dual-clutch transmissions originated from motorsports. Their first practical application was in the early 1980s with the Porsche 962C and the 1985 Audi Sport Quattro S1 RC racing cars. However, due to durability and other issues, they were not widely adopted. It wasn't until 2003 that Volkswagen introduced the Golf equipped with a dual-clutch transmission, becoming the first automaker to bring this technology to the mainstream consumer market. 2. Advantages: The benefits of dual-clutch transmissions are evident, including high transmission efficiency, fast gear shifts, low production costs, compact size, and low fuel consumption, among others.

DCT is indeed an automatic transmission because it eliminates the need for drivers to manually operate the gear lever or clutch pedal. The working principle of a dual-clutch transmission is as follows: it features a dual-clutch and dual-gear set design, which allows pre-selection of the next gear, enabling almost seamless shifting with faster response and lower fuel consumption compared to traditional automatic transmissions. I've driven cars like the Volkswagen Golf GTI, and the experience feels like driving a high-performance sports car—smooth acceleration without any jerking, making it particularly suitable for relaxed driving in urban traffic jams. Essentially, DCT inherits the mechanical efficiency of manual transmissions but operates fully automatically, so whether for daily commuting or sporty driving, it belongs to the automatic transmission family.

How Often Should Car Antifreeze Be Refilled?

Car antifreeze should be refilled every two years or 40,000 kilometers, whichever comes first. The method for changing antifreeze: 1. Locate the antifreeze reservoir and follow the storage tank to find the lower hose; 2. Find the position of the hose clamp, use clamp pliers to grip the clamp, squeeze the pliers firmly to open the clamp and lock it; 3. Pull the rubber hose forcefully, and the antifreeze will flow out; 4. After the antifreeze has completely drained, you can refill with new antifreeze or clean the system before refilling. The full name of antifreeze should be antifreeze coolant, meaning it is a coolant with antifreeze properties. It prevents the coolant from freezing and expanding in cold winter conditions, which could crack the radiator or damage the engine cylinder block or head. Antifreeze also reduces corrosion in the engine cooling system and has anti-corrosion and rust-removal functions.
