What is the engine speed of a CVT transmission?
2 Answers
CVT engine speed is around 2500 rpm. CVT usually refers to a type of automotive transmission, also known as a continuously variable transmission. In a CVT transmission system, traditional gears are replaced by a pair of pulleys and a steel belt. Each pulley is actually a V-shaped structure composed of two conical discs. The engine shaft is connected to the small pulley, which drives the large pulley through the steel belt. Relevant information about the transmission is as follows: 1. Introduction: A device that changes the speed ratio and direction of motion. It is used to alter the torque, speed, and direction of motion transmitted from the driving shaft to the driven shaft under different working conditions. A gear-driven transmission generally consists of a housing and several gear pairs. 2. Function: While driving, to adapt to different working conditions, the driving force and speed of the car need to vary within a certain range. However, the existing engine's torque and speed variation range cannot meet this requirement, hence the transmission is set up.
I've been driving CVT cars for many years. It's quite common for the engine speed to surge to four or five thousand RPM during acceleration, which feels very responsive. But during cruising, it automatically drops to around two thousand RPM, making the ride quiet and fuel-efficient. The essence of CVT design is to keep the engine in the efficient zone, with RPM adjusting according to speed and throttle. When driving gently, the RPM stays stable at the lower end, but it goes higher in traffic jams or uphill. Pay attention to regular transmission fluid maintenance, otherwise poor lubrication can lead to abnormally high RPM and affect the lifespan. From a driving experience perspective, the RPM fluctuates significantly but remains smooth without any jerking, which is distinctly different from traditional automatic transmissions. Once you get used to it, it's particularly hassle-free.
