What is the principle of a CVT transmission?

The principle of a CVT transmission is that the CVT uses a transmission belt and a variable-width pulley for power transmission. When the pulley changes its groove width, it correspondingly alters the contact radius of the driving wheel and the driven wheel on the transmission belt to achieve speed variation. The transmission belt is generally made of rubber belts, metal belts, or metal chains. Below is some information about CVT transmissions: CVT usually refers to a type of automotive transmission, also known as a continuously variable transmission. The difference between a CVT and a stepped transmission is that its gear ratio is not a series of discrete points but a continuous range of values, thereby achieving good fuel economy, power performance, and smooth driving, while also reducing emissions and costs. For example, it can vary continuously from 3.455 to 0.85. The structure of a CVT is simpler and more compact than that of a traditional transmission. It does not have the numerous gear pairs of a manual transmission or the complex planetary gear sets of an automatic transmission. It mainly relies on the primary and secondary pulleys and a metal belt to achieve continuously variable gear ratios.

What are the methods for cleaning carbon deposits?

The specific operation methods for cleaning carbon deposits are as follows: 1. Cleaning carbon deposits inside the engine: Before replacing the new engine oil, open the oil cap, add a cleaning agent, mix it with the old oil, and let the engine idle for about 10 minutes. 2. Cleaning carbon deposits in the intake system mainly refers to cleaning carbon deposits inside the intake tract and intake manifold. The purpose is to remove carbon deposits inside the intake system, increase the intake flow and speed, and reduce engine shaking and unstable idling. Prepare an intake system cleaner, use a dedicated cleaning device's liquid storage tank, connect it to the intake system, and use vacuum to draw the cleaner into the intake tract to achieve the cleaning purpose. 3. Remove the throttle body, use carburetor cleaner to clean the front and back of the throttle body, and wipe it dry with a clean cloth. It is recommended to clean the throttle body when the car has been used for one year or has traveled 20,000 kilometers. However, it should be noted that different car models have different cleaning cycles, which should be determined based on the car's own condition.

Non-commercial vehicles and commercial vehicles have different retirement periods, as detailed below: Retirement regulations for non-commercial vehicles: For household 5-seat sedans and 7-seat SUVs, as well as small and micro non-commercial vehicles, there is no service life limit. When the normal mileage reaches 600,000 kilometers, the state will guide the retirement. In addition to the above vehicles, small and micro non-commercial passenger vehicles, large non-commercial sedans, and wheeled special machinery vehicles also have no service life limit. Common retirement regulations for commercial vehicles: Small and micro taxi passenger vehicles have a retirement period of 8 years, medium-sized taxi passenger vehicles have a retirement period of 10 years, and large taxi passenger vehicles have a retirement period of 12 years. Public transport passenger vehicles have a retirement period of 13 years, other small and micro commercial passenger vehicles have a retirement period of 10 years, and large and medium-sized commercial passenger vehicles have a retirement period of 15 years. Micro commercial trucks have a retirement period of 8 years, light and large commercial trucks have a retirement period of 10 years. The vehicle retirement process is as follows: The car owner applying for retirement renewal must fill out one copy of the "Motor Vehicle Change, Transfer, Modification, Suspension, Retirement Approval Application Form" and stamp the owner's seal. The registration department will accept the application and issue a "Vehicle Retirement Notice" for vehicles that have reached the retirement period. For vehicles that have not reached the retirement period, after inspection by the motor vehicle inspection department, if they meet the vehicle retirement standards, a "Vehicle Retirement Notice" will be issued. The owner can choose a qualified recycling company to dismantle the vehicle with the "Notice". The recycling company will dismantle the vehicle and take photos after verifying the "Notice". The engine must be separated from the vehicle, the engine block must be broken, and the frame (chassis) must be cut. The owner must submit the "Change Form", "XX Province Updated Vehicle Technical Appraisal Form", "Retired Vehicle Recycling Certificate", and vehicle dismantling photos to the motor vehicle inspection department for verification and signature. The license plates will be recovered, and the retirement registration will be processed after approval according to regulations. Special notes: According to Article 30 of the "Motor Vehicle Registration Regulations", if the vehicle cannot be driven back to the registration location due to damage, the owner can sell the retired vehicle to a local motor vehicle recycling company. If a commercial vehicle is converted to a non-commercial vehicle, it must be retired according to the original commercial vehicle's retirement period. According to Article 43 of the "Motor Vehicle Registration Regulations", after completing the transfer or cancellation registration of a motor vehicle, the original owner can apply to use the original license plate number when registering a newly purchased vehicle. The application must meet the following conditions: (1) The application must be submitted within six months after the transfer or cancellation registration; (2) The owner must have owned the original vehicle for more than three years.

What should be considered when choosing engine oil for turbocharged cars?

Details to consider when selecting engine oil for turbocharged cars are as follows: 1. Turbocharged cars have higher requirements for the engine compared to naturally aspirated ones, as their internal components need to withstand high temperatures and more intense impacts, compression, and other working conditions. Therefore, when choosing engine oil for turbocharged cars, it is essential to select oil with good anti-wear properties, high-temperature resistance, and superior lubrication. Fully synthetic or semi-synthetic oils meet these requirements perfectly. Besides using the manufacturer-recommended oil, fully synthetic and semi-synthetic oils are excellent choices. 2. In addition to the above characteristics, engine oil suitable for turbocharged cars must also have good oxidation resistance. In high-temperature working environments, oil with poor oxidation resistance can easily degrade and become ineffective.
