Continuously variable transmission is a gearbox without discrete gear ratios, meaning it has no fixed gear positions. Working principle of continuously variable transmission: It works by wrapping both ends of a transmission belt around a conical pulley, where the outer diameter of the pulley changes continuously via hydraulic pressure. During startup, the driving pulley's diameter becomes the smallest while the driven pulley's becomes the largest, achieving a higher transmission ratio. Function of continuously variable transmission: Continuously variable transmission refers to a system that can continuously obtain any transmission ratio within its range. It enables optimal matching between the drivetrain and engine operating conditions. Common types include hydro-mechanical CVT, metal belt CVT (VDT-CVT), and variable-angle CVT.

What are the exhaust emission testing data standards?

Automotive environmental exhaust emission testing standards set the limit for carbon monoxide at 6.3g/km, and the total limit for hydrocarbons and nitrogen oxides at 2.0g/km. Below are the specific details about exhaust emission testing: 1. Testing Basis: Automotive exhaust emission testing is based on whether the smoke opacity value meets the standards, and whether emissions meet the standards is primarily determined by vehicle testing data, confirming compliance based on the smoke opacity value. 2. Inspection Authorities: Motor vehicle exhaust inspections are conducted jointly by the environmental protection administrative departments and public security traffic management departments for law enforcement checks. Traffic police officers are responsible for directing, intercepting vehicles, and handling vehicles that exceed standards, while environmental protection personnel are responsible for monitoring. Law enforcement officers explain the situation to the parties on the spot. 3. Standard Values: Depending on the vehicle type, total vehicle mass, year of manufacture, and fuel type, the standard values vary.

Is It Normal for the Car Interior to Be Damp on Rainy Days?

It is normal for the car interior to be damp on rainy days. Precautions for driving in the rain: 1. Slow down: Visibility is low in rainy weather, and the field of vision is poor. The braking distance and other emergency performance of the vehicle will also be reduced, so it is necessary to slow down in advance, leaving sufficient time and space to handle situations and ensure safety. 2. Maintain distance: Driving in the rain can obstruct your vision, so it is important to maintain a safe distance between vehicles, constantly observe the distance to the vehicles in front and behind, and increase the safety margin. 3. Do not restart after stalling: In heavy rain or stormy weather, some road sections may become severely waterlogged in a short time. If you must drive through water, use a low gear and pass at a constant speed. If the vehicle stalls while moving, do not attempt to restart it immediately. Blindly restarting may cause the engine to be irreparably damaged. After the vehicle stalls, you should promptly contact a specialized repair shop. Only after the maintenance personnel have inspected the vehicle on-site and confirmed that there are no issues can the vehicle be restarted.
