Please check TPMS means to check the Tire Pressure Monitoring System. When a car displays a TPMS alert, it indicates the Tire Pressure Monitoring System is signaling that there's no signal from one of the tires. The reasons for the TPMS warning light to illuminate are: 1. A punctured tire; 2. Excessive tire pressure; 3. Prolonged driving with low tire pressure; 4. Decreased tire pressure due to prolonged lack of inflation. The working principle of the TPMS is: it automatically monitors the tire pressure in real-time while the car is in motion and alerts the driver to tire leaks or low pressure to ensure driving safety. When the pressure in a tire decreases, the rolling radius of that wheel becomes smaller, causing it to rotate faster than the other wheels. By comparing the rotational speed differences between tires, the system monitors the tire pressure.

What is the typical transmission efficiency of a CVT?

Manual transmissions have the highest efficiency, reaching up to 98%; dual-clutch transmissions rank second with an efficiency of up to 96%; AT transmissions have an efficiency of 91%; while CVT transmissions have an efficiency of 87%. Below is an introduction to automotive transmissions: Transmission: A device that changes the speed ratio and direction of motion. Used in automobiles, tractors, ships, machine tools, and various machinery, it alters the torque, speed, and direction of motion transmitted from the driving shaft to the driven shaft under different working conditions. Gear-driven transmissions generally consist of a housing and several gear pairs. Function of the Transmission: While driving, to adapt to different operating conditions, a vehicle's driving force and speed need to vary within a certain range. However, the torque and speed variation range of existing engines cannot meet this requirement, hence the installation of a transmission.

Why is the D941 bullet train sometimes available and sometimes not?

Shanghai to Zhuhai D941 bullet train runs daily. The D941 is a high-speed EMU (Electric Multiple Unit) from Shanghai Hongqiao to Zhuhai, covering a distance of 1841 kilometers and taking 12 hours and 34 minutes. Below is an introduction to the D941 bullet train: Bullet Train: Bullet train, fully known as powered vehicle, refers to vehicles equipped with power devices in rail transit systems, mainly including locomotives and powered carriages. Bullet trains are equipped with driving wheels, while vehicles without driving devices are called trailers. For a train to operate normally on the tracks, there must be bullet trains to provide sufficient traction for the entire train, but it is possible not to attach trailers without power. D941: The D941 is a high-speed bullet train from Shanghai Hongqiao to Zhuhai, covering a total distance of 1841 kilometers and taking 12 hours and 34 minutes. The departure time is 19:55, and the arrival time is 08:29.

How is the oil quality at illegal gas stations?

Illegal gas stations cannot guarantee the source channels and quality of their oil products, often selling substandard fuel with unassured quality. Here are detailed explanations of relevant information: Hazard information: Inaccurate measurements cheat the fuel tank. Using such oil can cause engine carbon buildup, clog the fuel system, and lead to failure of the vehicle's oxygen sensor and three-way catalytic converter. Difficulties in rights protection cheat customers, excessive emissions harm the environment, and tax evasion cheats the nation. Illegal gas stations operate without licenses and evade tax responsibilities. Precautions: Driven by profit, illegal gas stations mostly sell inferior diesel, far below the national China V standard. Oil quality test results consistently show non-compliance.

What is the fuel consumption per 100 kilometers for a flatbed truck?

Depending on the model, the fuel consumption of large flatbed trucks on highways varies, with most models consuming between 35L and 45L. Fuel consumption per 100 kilometers: Fuel consumption per 100 kilometers refers to the amount of fuel a vehicle consumes when driving a distance of 100 kilometers at a certain speed on the road. It is a theoretical indicator for vehicles. The fuel consumption per 100 kilometers is a value measured by manufacturers in an objective environment using a dynamometer installed on the vehicle's chassis, converted into speed parameters, and then calculated under specified speed conditions to determine the theoretical experimental fuel consumption data per 100 kilometers for the model. Road condition fuel consumption: Road condition fuel consumption is a fuel indicator calculated by repeatedly testing the values measured when a vehicle travels on specified roads at specified speeds and times, also known as multi-condition road cycle fuel consumption. The standard specifies that each cycle includes various driving conditions and records driving conditions based on various indicators such as specified gear shift times, parking times, driving speeds, acceleration, braking, and deceleration in each cycle. The measured values obtained by this method are closer to actual values.

What documents and procedures are required for a new car?

There should be the vehicle registration certificate, vehicle license, vehicle purchase tax payment certificate, annual inspection compliance sticker, green environmental protection sticker, and compulsory traffic insurance sticker. Below is relevant information: 1. Vehicle License: The vehicle license is the most important document. Once license plates are obtained and the car is on the road, the vehicle license must be present and carried with the vehicle at all times. Compulsory traffic insurance is also mandatory for vehicles on the road and must be prominently displayed on the front windshield. The vehicle compliance certificate, which proves the vehicle is free from defects or safety issues, must also be prominently displayed on the front windshield. 2. Buying a Car on Loan: If the car is purchased through a loan or installment plan, the purchase invoice and the vehicle registration certificate must be mortgaged to the bank. Only after the loan is fully repaid and a loan clearance certificate is obtained from the bank can these documents be retrieved. Additionally, the vehicle registration certificate and purchase invoice are required when completing the vehicle release procedures after the loan is repaid.

What are the reasons for the slow inflation of a newly replaced air pump?

Reasons for the slow inflation of a newly replaced air pump: Spiral impeller: Check if the spiral impeller is installed in the wrong direction. Air pipe, motor, and impeller: Also, check if there are any issues with the air pipe below the air pump, the motor, and the surrounding area of the impeller. Motor coil: The motor coil is damaged, or the air pump diaphragm is damaged. Air pump: The motor of the air pump is damaged; whether the air pump belt is too loose; the air pump intake filter is dirty and clogged. Exhaust valve: The steel plate of the intake and exhaust valves is worn, causing poor sealing. Piston: The piston rings are misaligned or worn; the cylinder piston or cylinder liner is worn or out of round. This can determine that the fault lies between the air pump and the air storage cylinder.
