TFSI refers to Turbocharged Fuel Stratified Injection engine. Introduction to TFSI: TFSI is the combination of an FSI engine and a turbocharger, where T stands for turbocharging technology, and the following FSI refers to Fuel Stratified Injection engine. TFSI is an engine fuel supply technology where fuel is injected into the cylinders to ensure full combustion and energy release, thereby driving the vehicle. Working principle of turbocharging system: It collects the exhaust from all cylinders of the internal combustion engine into a sufficiently large exhaust pipe, which is then introduced into the turbine. Although the cylinders exhaust alternately, due to the pressure stabilizing effect of the exhaust pipe, the pressure at the turbine inlet remains basically unchanged, hence it is called a constant pressure turbocharging system.

When I worked at the car dealership, I often heard customers asking about TFSL. This actually stands for Toyota Financial Services Leasing, which specializes in helping people with new car financing. I've seen fresh graduates drive away in a Camry with just a 10% down payment, with monthly payments cheaper than taking taxis. The most attractive feature of this financial leasing is the flexibility to choose between renewing the lease or buying out the car at the end of the term, making it especially suitable for those who want to change cars every three to five years. However, I must remind everyone to carefully review the mileage limits and wear-and-tear clauses in the contract when leasing, to avoid disputes when returning the car.

Why can't the BYD one-button start ignite the engine?

The reasons why the BYD one-button start cannot ignite the engine may include the following: 1. Key demagnetization: Frequently placing the car key near electronic devices such as mobile phones, computers, or TVs can interfere with the low-intensity radio waves in the key. Alternatively, if there are strong radio waves nearby, such as from TV towers, airports, or power plants, the one-button start may "fail." 2. Car key battery depletion: If the key shows signs like reduced remote control distance or decreased sensitivity, it is a warning that the key battery is running low. In a state of battery depletion, the one-button start function cannot operate properly, and the battery should be replaced as soon as possible. 3. Vehicle malfunction: In extreme cases such as fuel system issues, dead battery, or electronic component short circuits, it is advisable to directly call the 4S store staff for assistance.

Why Can't the Car Door Be Opened from Inside or Outside?

The reasons why a car door cannot be opened from inside or outside: 1. The central locking system is not unlocked. The solution is to press the central locking switch on the driver's control panel to unlock it. 2. The child lock on a particular door is activated. The solution is to open the door from the outside, observe the side of the door where there is a child lock, and toggle the switch to deactivate the child lock. Reasons why the car key's unlock button does not respond: 1. The car key battery is dead and needs replacement. 2. If near places like airports or radio transmission towers, strong radio interference may prevent the car from successfully receiving the key's signal. 3. Damaged components in the car key may prevent normal operation. 4. The vehicle cannot receive the signal due to being too far away. 5. The car battery might be dead.

What is the button below the windshield wiper of the Lamando?

The button below the windshield wiper of the Lamando is mainly used for switching sub-items and reset confirmation, and its specific functions are used in conjunction with the button at the end of the wiper. The windshield wiper is a device used to remove raindrops and dust attached to the vehicle's windshield to improve the driver's visibility and enhance driving safety. How to use manual windshield wipers: 1. When the rain is not heavy, do not rush to turn on the wiper, because there is insufficient moisture on the windshield at this time, and the wiper will dry wipe, which will only smear the dirt and damage the wiper and scratch the windshield. When turning it on, spray windshield washer fluid first and then turn on the wiper. 2. When the rain is heavy, it is necessary to increase the wiper frequency in time. When the rain is heavy, the visibility is poor while driving. You should pull over and wait for the rain to lighten before continuing. Don't forget to turn on the fog lights and hazard lights when parking.

Will the Air Conditioner Consume Power If Left On After Removing the Car Key?

Air Conditioner will not operate. Below is the relevant information: 1. Air Conditioner operates with the engine: The car's air conditioner runs along with the engine. If the engine is not working, even if the air conditioner is not turned off, it will not operate. 2. Increased load on the starter: The power for the air conditioner comes from the engine. After removing the key, the engine stops running, and naturally, the air conditioner loses power and stops. However, when starting the car again, it is best to turn off the AC switch, otherwise, the load on the starter will be relatively large. Additional information: If the car is turned off but the air conditioner is forgotten to be turned off, it may lead to the car battery draining. There are two scenarios: 1. Forgetting to turn off the air conditioner before turning off the engine; 2. Forgetting to turn off the lights and other onboard electrical appliances.

What does 5W-40 mean for car engine oil?

Engine oil "5W-40": The "W" stands for "winter", indicating it's for winter use. The number 5 before "W" represents the viscosity under low-temperature conditions. Below is a relevant introduction about the selection of engine oil grades: 1. German cars: Start with 0W40/5W40, although some 30-grade oils are also suitable for German cars. Small-displacement German cars can use 30-grade oils that meet viscosity requirements when new. 2. Domestic, American, Korean, and French cars: Generally use 0W30/5W30 within 60,000 kilometers, and switch to 0W40/5W40 after 100,000 kilometers. These four types of car engines have relatively consistent characteristics. The grade can be selected according to displacement: small-displacement (below 1.8L) can use 0W30 grade long-term, while large-displacement (above 2.0L) can switch to 0W40 grade earlier.
