What does CTV mean in cars?

[OLeah]

There is no CTV in cars, only CVT. CVT refers to the Continuously Variable Transmission, which is a type of transmission in automatic vehicles. It can continuously obtain any transmission ratio within the speed range, achieving a good match between the transmission system and engine conditions through continuously variable speed. Transmissions are categorized into AT (Automatic Transmission), CVT (Continuously Variable Transmission), AMT (Automated Manual Transmission), and DCT (Dual Clutch Transmission). The working principles of transmissions are as follows: 1. Manual transmissions consist of gears and shafts, achieving speed and torque variation through different gear combinations; 2. Automatic transmissions consist of a torque converter, planetary gears, and a hydraulic control system, achieving speed and torque variation through hydraulic transmission and gear combinations.

I've been driving for almost 20 years and noticed many people mistakenly write CVT as CTV. It actually refers to the continuously variable transmission. This thing works like a bicycle chain that can adjust gear ratios anytime, using steel belts and conical pulleys instead of traditional gears. It drives exceptionally smooth, and your foot doesn't need to frequently adjust the throttle in traffic jams. However, the engine roars loudly when climbing steep slopes - I encountered this situation last year while driving on the Sichuan-Tibet line. My Japanese car has been running for eight years, and mechanics always remind me to change the dedicated transmission fluid regularly during maintenance. Otherwise, steel belt slippage could cost thousands to repair.

Last week, I accompanied a friend to look at cars, and the salesperson kept boasting about the fuel efficiency of CTV. Actually, it's the CVT transmission, which adjusts the speed by regulating the distance between the cone discs through a hydraulic system. This design keeps the engine at the optimal RPM, making it indeed fuel-efficient for city commuting. However, during aggressive driving, the power response can be delayed, which might not suit those who enjoy a strong sense of acceleration. It's advisable to pay attention to the manufacturer's warranty policy when choosing a car, as CVTs from some brands are prone to issues. My neighbor's SUV had its transmission valve body replaced after just 50,000 kilometers, and the repair cost was enough to buy a new smartphone.

After researching automotive transmission structures, CTV should refer to the CVT continuously variable transmission. The patent was first filed in 1896, but it didn't become widespread until the 1980s. Modern CVTs use high-strength steel belts to transfer power, making them 15% lighter than traditional transmissions. I measured the fuel consumption of a Nissan Sylphy, and it saves 0.8 liters in city driving compared to a manual transmission. However, pay attention to cold start protection—it's best to warm up the car for thirty seconds before driving in northern winters. Nowadays, hybrid vehicles often use E-CVT, which is actually a planetary gear structure and not the same as the CVT in pure gasoline vehicles.

When repairing cars, we often encounter CTV failure cases, to be precise, CVT transmission issues. The most common problem is valve body sticking causing jerking, and disassembly and cleaning cost about 400 yuan. The design flaw is that excessive oil pressure can burst the oil seal, and I dealt with an oil leakage case last month. It's recommended to change the original transmission oil every 40,000 kilometers, and never use the wrong type. Belt wear can produce metal shavings, so remember to check the magnet during maintenance. The newly introduced chain-type CVT is more durable, but the repair cost is still significantly higher than manual transmissions.

After comparing various transmissions, CTV is actually CVT (Continuously Variable Transmission). Its core advantages lie in smoothness and fuel efficiency, making it particularly suitable for beginners and family vehicles. However, transmission efficiency decreases during aggressive driving. Based on my thermal attenuation test data, there is a 12% greater power loss compared to dual-clutch transmissions during continuous uphill climbs. When selecting, pay special attention to the cooling system, as some models with additional transmission oil coolers prove highly effective. In the long run, electric motor drives may be the trend, but currently, it remains a mainstay configuration for economy cars.
