What does Audi TFSI mean?

TFSI stands for T+FSI, where T represents turbocharging, and FSI represents direct fuel injection. The number preceding TFSI indicates the standard acceleration time from 0 to 100 km/h. For example, 30TFSI is approximately 9.35 seconds; 40TFSI is 7.6 seconds; 45TFSI is around 6.5 seconds, and the highest, 50TFSI, is 6 seconds. More extended information is as follows: 1. TFSI is T+FSI: T stands for turbocharging, and FSI is the abbreviation for Fuel-Stratified-Injection, which means fuel stratified injection technology in Chinese. It represents a future direction for engine development. Fuel stratified injection technology is a type of lean-burn technology for engines. 2. Lean burn: This means the gasoline content in the engine's air-fuel mixture is low, with a gasoline-to-air ratio that can reach 1:25 or higher. FSI can directly inject fuel into the combustion chamber, reducing the engine's heat loss, thereby increasing output power and reducing fuel consumption, which benefits both fuel economy and performance. 3. Characteristics of the high-pressure fuel pump: The Volkswagen FSI engine uses a high-pressure fuel pump to deliver gasoline through a split rail (common rail) to electromagnetically controlled high-pressure injectors. Its feature is that a variable vortex is already generated in the intake tract, forming the optimal vortex pattern for the intake flow to enter the combustion chamber, pushed in a stratified filling manner, concentrating the mixed gas around the spark plug located at the center of the combustion chamber. This allows the lean-burn technology to achieve a mixture ratio of over 25:1, which cannot be ignited under normal circumstances, necessitating a stratified combustion approach from rich to lean. Through the movement of air within the cylinder, a rich mixture that is easy to ignite forms around the spark plug, with a mixture ratio of about 12:1, gradually thinning out towards the outer layers. Once the rich mixture is ignited, combustion rapidly spreads to the outer layers.

Can the parking air conditioning be used while the vehicle is moving?

Yes, the parking air conditioning can be used while the vehicle is moving. Here are the relevant details: 1. Parking Air Conditioning: It is an in-vehicle air conditioning system designed to operate using the vehicle's DC power supply (12V/24V/36V) during parking, waiting, or resting periods. It regulates and controls parameters such as temperature, humidity, and airflow within the vehicle cabin, providing comfortable cooling for truck drivers. 2. Components: Typically includes a refrigerant delivery system, cooling source equipment, terminal units, and other auxiliary systems. Main components consist of: condenser, evaporator, electronic control system, compressor, fan, and piping system.

How to Drive When Encountering Slow-Moving Vehicles Ahead?

When all vehicles ahead are moving slowly, it is necessary to maintain a safe following distance. Below are some precautions regarding car driving: 1. Cold Engine Warm-up: Proper warm-up helps form an "oil film" between engine components, reducing wear. 2. Timely Gear Shifting: When driving a manual transmission vehicle during the break-in period, shift gears promptly and appropriately to avoid incorrect behaviors like high gear with low RPM or low gear with high RPM, and do not use a single gear for extended periods. 3. Timely Maintenance: Simply follow the manufacturer's recommendations in the vehicle manual, and perform timely inspections and maintenance after reaching certain mileage or time intervals, including oil and oil filter changes, along with a comprehensive check of the chassis system. 4. Avoid Emergency Braking: Emergency braking not only shocks the braking system during the break-in period but also increases the impact load on the vehicle's chassis and engine.

How to Use Lights on Unlit or Poorly Lit Roads?

When driving at night on roads without streetlights or under poor lighting conditions, it is necessary to turn on the high beams. Here is more information about high beams: 1. The difference between high beams and low beams: Both high beams and low beams serve the function of nighttime illumination. High beams have a higher angle and longer range, while low beams have a lower angle and shorter range. 2. The dangers of indiscriminate use of high beams: Avoid using high beams when driving in urban areas. In large cities with good lighting conditions, the high angle of high beams can easily dazzle oncoming drivers and pedestrians, posing a significant hazard. 3. The uses of high beams: Alternately switching high beams on and off at night can serve as a substitute for honking to alert nearby pedestrians and vehicles. High beams can be used on highways or in rural areas without streetlights, but they should be switched to low beams when encountering oncoming traffic.
