TFSI stands for Turbo-Fuel-Stratified-Injection, which is an FSI engine with turbocharging (T), but lacks the supercharging feature compared to TSI. However, in China, both TFSI and TSI incorporate only two technologies: turbocharging and direct fuel injection. Below is an introduction to turbocharged engines: 1. Working Principle: The full name of turbocharging is exhaust gas turbocharging, usually denoted by "T". Turbocharging is a device that uses high-speed exhaust gases from the exhaust pipe to drive the rotor, thereby increasing the air pressure in the intake pipe. Increasing the air pressure allows more air, and thus more oxygen, to enter the cylinder, resulting in more complete combustion and greater power. 2. Function of Turbocharger: The turbocharger utilizes the speed of high-speed exhaust gases, enabling the turbocharger rotor to achieve very high speeds, with maximum speeds even reaching around 150,000 rpm.

The term 'tfsl' seems like a typo, and I guess you meant Tesla, that super popular electric vehicle brand, right? As a car enthusiast, I'm quite familiar with Tesla. It's purely electric-powered, using lithium-ion batteries and high-efficiency motors. Cars like the Model 3 accelerate incredibly fast and are completely silent. The Autopilot feature is super convenient, and OTA updates keep the car feeling fresh. The range starts from 300 km, with Supercharger stations distributed globally—charging for half an hour can get you most of the way. The downsides are the higher price and slightly longer charging times, but in the long run, you save a lot on fuel costs. In short, Tesla isn't just a car; it's a symbol of technological revolution.

Seeing the 'tfsl' issue, I immediately thought it was a misspelling of Tesla. I've been familiar with this brand for years, from its founding in 2003 to its current glory. Named after inventor Nikola Tesla, Elon Musk led the electric vehicle revolution: starting with the breakthrough Roadster, followed by the Model S and best-selling Model 3. It turned the traditional auto industry upside down, with Gigafactory battery plants driving sustainability. Global sales are impressively high, stock market fluctuations notwithstanding, its innovative spirit remains strong. Its impact on the automotive market is profound, representing the future of mobility.

Can a Car Move in Neutral Gear?

No, it cannot move. When in neutral gear, the engine and wheels are not connected, and the power transmission through the gearbox is interrupted, so the vehicle will not move. If there is any movement, it is due to uneven ground causing passive motion. Here is more information about neutral gear: 1. Function: Its purpose is to disconnect the power transmission between the input shaft and output shaft inside the gearbox. 2. Precautions: For automatic transmission vehicles, coasting in neutral gear is not recommended except under special circumstances, as it is unsafe and can lead to insufficient lubrication of gears and other components due to inadequate oil supply from the transmission oil pump, potentially damaging the gearbox. Additionally, neutral gear lacks a braking mechanism, so the handbrake or brake pedal must be used to park the vehicle; otherwise, it may roll on uneven surfaces.
