The principle of continuously variable transmission is to use a hydraulic torque converter to generate different levels of torque, transmitting force to achieve stepless speed variation. Types of continuously variable transmission: 1. Mechanical type: There are various forms, with the most common being the cone-block metal V-belt drive, used in automobiles; 2. Hydraulic transmission type: Used in engineering vehicles and agricultural machinery; 3. Electric type: Used in electric vehicles. Starting devices for continuously variable transmission include: 1. Electromagnetic clutch type: Large in mass and size, with low thermal load capacity; 2. Electronically controlled wet friction plate type: Compact structure, fast response, and low energy loss; 3. Hydraulic torque converter type: High starting torque, good hill-start performance, easy driving, excellent driving performance, and capable of reducing vibrations and shocks caused by uneven engine torque.

The essence of continuously variable transmission lies in its variable gear ratio design, achieved through a pair of tapered pulleys connected by a steel belt or chain. The driving pulley links to the engine while the driven pulley connects to the wheels. By hydraulically adjusting the distance between the two tapered pulleys, the working radius of the belt changes. When the computer detects acceleration demand, it instantly adjusts oil pressure to increase the driving pulley's diameter while reducing the driven pulley's size – much like shifting gears on a bicycle. This creates seamless ratio changes without fixed gear steps, eliminating traditional transmission shift shock completely. Driving such vehicles on mountain roads keeps engine RPM consistently in the optimal range, delivering both fuel efficiency and smoothness. Even in stop-and-go traffic, there's no jerky motion. While belt wear and higher maintenance costs remain weaknesses, most new models now use reinforced chains to address this issue.

Car maintenance, also known as car servicing, mainly aims to keep the car clean, eliminate potential hazards under normal technical conditions, prevent accidents, slow down the aging process of car parts, extend their service life, and ensure the car works properly.

What is the principle of the engine valve train?

The principle of the engine valve train is to open and close the intake and exhaust valves of each cylinder in a timely manner according to the working cycle and ignition sequence requirements of each cylinder of the engine, allowing fresh air to be drawn into the cylinder and exhaust gases to be expelled from the cylinder after combustion. Depending on the installation position of the valves, the valve train can be divided into two types: overhead valve train and side valve train. An engine is a machine that converts other forms of energy into mechanical energy, originating in the UK. It can refer to both the power generation device and the entire machine including the power unit. Types of engines include internal combustion engines (gasoline engines), external combustion engines, electric motors, etc.
