Continuous Variable Transmission : Advantages & Disadvantages

Continuous variable transmission or CVT as its commonly known is a type of automatic transmission which automatically changes the speed ratio between the engine and wheels of an automobile. Unlike conventional gearboxes which are limited by ratios, CVT has the advantage of having infinite speed ratio.Like any other transmission technology in the market today CVT also has its fair share of Pros & Cons. Here we will be discussing the advantages and disadvantages of a continuously variable transmission system.

Advantages of a Continuous variable transmission system :

(a) Design Factor: Unlike traditional manual or even automatic transmissions, CVT by nature are simple by design.Inside a Continuously variable transmission system box, the actual working and moving components are much less making it more compact. This makes it the ideal for compact vehicles and two-wheelers.

(b)Acceleration Advantage: In manual and traditional automatic transmission the process from stop to start and de-accelerating is seldom smooth.This is due to the various stages of mechanical processes happening to give the desired acceleration. In case of CVT, the acceleration is really smooth as varies the gear ratio continuously and seamlessly. CVT also provides greater torque as it allows the engine to rev up in the least time possible.

(c) Fuel Efficiency: There is a constant change in ratio with respect to engine shaft speed and drive shaft speed in a CVT system, additionally the CVT system is also armed with an array of sensors which keep the power delivery in check irrespective of the speed of the vehicle and the engine.All this results in a greater fuel economy and efficiency specifically in a start-stop city like traffic conditions. This also leads to a greener engine as the emissions are well in check.
