The automotive industry continuously innovates resulting in efficient and technologically advanced auto parts. The prime example of this innovation is the Electronically-Controlled Continuously Variable Transmission (E-CVT). It is one of the modern types of transmission systems, more prevalent in hybrid vehicles. Alongside better fuel economy, the transmission is known for smooth gear transitions.
Let’s dive deeper into E-CVT and elaborate on its pros and how it’s different from other transmissions.
E-CVT Meaning
E-CVT is an intelligent car transmission with infinite gear ratios. The transmission analyses vehicle speed, driver’s input and road conditions and selects the gear ratio according to it. The planetary gears allow transmission to smoothly transition from one gear ratio to another. This system is relatively different from the conventional Continuously Variable Transmission (CVT).
Now that you are aware of E-CVT, let’s move towards its working.
E-CVT Working
The working of E-CVt is different from a conventional CVT. An E-CVT uses two electric motors connected to the car battery. A transmission shaft and planetary gear shaft connect motor 1 and the internal combustion engine. Whereas, motor 2 is connected with the engine through a ring gear set. When all these gears rotate, a required gear ratio is provided to rotate the wheel.
Pros and Cons of E-CVT Transmission
Following are the pros and cons of the E-CVT transmission system in vehicles.
Pros of Electronic CVT
Here are the pros of E-CVT.
- Improve Efficiency: E-CVT is compact which reduces the overall vehicle weight. Moreover, it uses a combination of electric motors and internal combustion engines, leading to increased efficiency.
- Infinite Number of Gear Ratio: The planetary gear set and shafts provide a car with infinite gear ratios as per the requirement. This excludes the need for regular gear shifting which helps in achieving high speed.
- Higher Durability: An E-CVT does not use belts and chains like a conventional CVT. Therefore, the chances of malfunctioning are reduced leading to higher durability.
Cons of Electronic CVT
Mentioned below are some cons of E-CVT
- Require Proper Cooling: The transmission system requires proper cooling to ensure optimum functioning. That said, a regular transmission fluid change is obligatory in E-CVT.
- Battery Maintenance is Necessary: E-CVT uses a battery to support the internal combustion engine. This is why, if the battery malfunctions, the transmission is completely dependent on the engine resulting in reduced efficiency.
E-CVT Transmission Vs. CVT Transmission
A CVT is an innovative type of car transmission that uses a variable-width pulley and belt system to rotate the wheel. The variable-width pulley offers an infinite number of gear ratios which increases acceleration and fuel efficiency.
On the contrary, E-CVT uses a planetary gear set to rotate the wheels. Moreover, it also uses an electrical system to convert the power generated by the internal combustion engine. The combination of hybrid and internal combustion engines increases its efficiency more than a conventional CVT.
FAQs
What does E-CVT mean?
E-CVT means an Electronically-Controlled Continuously Variable Transmission that uses planetary gears instead of belts and chains.
Are CVT and E-CVT the same?
No, CVT and E-CVT are two different types of transmission.
Does E-CVT have driving modes?
Yes, E-CVT has different driving modes that vary from vehicle to vehicle. Usually, it has pure engine driving mode and pure electric driving mode.
This was all about E-CVT, its uses, pros and cons. E-CVT is an advanced type of transmission which is highly efficient and durable. Therefore, several leading automobile brands are offering E-CVT in their latest models.
