What does TSI mean on the back of a car?

TSI on the back of a car refers to a turbocharged fuel direct injection engine, which can convert all the energy stored in every drop of fuel into power, delivering stronger performance output. Below are the relevant details: 1. Turbocharging is a technology that uses exhaust gases generated by the internal combustion engine to drive an air compressor, with the purpose of increasing the engine's air intake, power, and torque. 2. A fuel direct injection engine can improve the fuel efficiency of an internal combustion engine by 20 percent, with the following benefits: (1) Reduced exhaust emissions. (2) Enhanced power performance. (3) Reduced engine vibration. (4) Improved fuel injection accuracy.

How to Unlock a Locked Driver's License?

What circumstances can lead to a locked driver's license: 1. Suffering from organic heart disease, epilepsy, Meniere's disease, vertigo, hysteria, tremor paralysis, mental illness, dementia, or other neurological diseases that affect limb movement and hinder safe driving. 2. Having used or injected drugs within the past three years, or having been released from compulsory isolation detoxification measures for less than three years, or being addicted to dependent psychotropic drugs and not yet having quit. 3. Committing a hit-and-run that constitutes a crime. 4. Causing a major traffic accident while driving under the influence of alcohol or drunk, which constitutes a crime. 5. Having the driver's license revoked for drunk driving or driving a commercial motor vehicle under the influence of alcohol within the past five years. 6. Having the driver's license revoked for drunk driving a commercial motor vehicle within the past ten years. 7. Having the driver's license revoked for other reasons within the past two years. 8. Having the driving permit revoked within the past three years. 9. Other circumstances stipulated by laws and administrative regulations.

What documents are required for the first maintenance of a new car?

Items required for the first maintenance include: driver's license; maintenance manual; warranty manual; owner's ID card; vehicle registration certificate; vehicle purchase invoice. Bring these to the designated first maintenance facility for the vehicle's initial service. Important note: Make an appointment with the 4S shop in advance. The first maintenance refers to the initial service after the new car has been driven. The specific time varies by car, but it is generally after driving 1,000 to 3,000 kilometers. It is essential to attend the first maintenance on time—neither early nor late. The completion of the first maintenance marks the end of the car's break-in period, allowing it to be driven under standard load and normal speed as required by the vehicle. The first maintenance time is calculated based on the car pick-up date. There are two indicators for the first maintenance: mileage and time. Whichever comes first will be the standard. The first maintenance items include: oil change, oil filter replacement, air filter cleaning, checking various fluid levels, inspecting the generator belt and wiper blades for damage, checking tire pressure and looking for tire damage or bulges. Estimated time: Approximately 2 hours to complete all tasks. The most critical part of the first maintenance for a new car is the oil and oil filter replacement. When changing the oil, the oil filter must also be replaced. The choice of oil must refer to the "Vehicle User and Maintenance Manual," as different car models require different oil specifications. Maintenance precautions: Do not rinse the interior of the car with water: Many people clean their cars during holidays, using water to wash the body and wiping it with a cloth. Here, it's important to note that the car's interior should not be directly rinsed with water. If the floor mats are dirty, use a vacuum cleaner or remove them, scrub with a brush and detergent, dry them, and then put them back. The rubber mats in the driver's floor have many drainage holes underneath. If water gets in, it won't dry naturally but will flow through these holes to areas like the gearbox, causing corrosion. The best practice is to clean with a vacuum cleaner and then wipe with a cloth to avoid water accumulation. Do not mix different brands of antifreeze: When the car's antifreeze is low, it is recommended to drain the existing antifreeze and refill it with the same brand from the start. Different brands of antifreeze have varying chemical properties, and the corrosion inhibitors in one brand may react negatively with those in another. Mixing different brands can lead to unnecessary issues. Do not lubricate wheel bolts and nuts: When bolts on a moving car rust, some people apply oil to make them functional again. To prevent rust on wheel bolts and nuts, some apply lubricant, but this can pose a safety risk. At high speeds, lubricated bolts and nuts may loosen or even fall off, leading to driving hazards. Do not press the accelerator when starting an EFI (Electronic Fuel Injection) car: The starting mechanism of EFI cars differs from conventional cars. The fuel injection control system automatically adjusts the fuel supply based on the engine's temperature and operating conditions, ensuring a smooth start.

The Difference Between Automatic and Manual Transmission?

Automatic and manual transmissions differ in the following ways: 1. Operation: Automatic transmissions do not require clutch pedals, having only brake and accelerator pedals; manual transmissions require clutch pedals for manual gear shifting and reversing. 2. Working Principle: Automatic transmissions use planetary gear mechanisms to change gears automatically based on accelerator pedal position and vehicle speed changes; manual transmissions change gear positions and transmission ratios by moving the gear lever to alter gear meshing positions inside the transmission. 3. Gear Indicators: Automatic transmission gear indicators are marked as P, R, N, D; manual transmission gear indicators are marked as 1, 2, 3, 4, 5, 6, R, etc.

Is Wheel Alignment Necessary After Tire Repair?

Wheel alignment is not necessary after tire repair. Wheel alignment is only required under certain circumstances, such as when the vehicle pulls to one side, the steering wheel does not return to center automatically, the steering feels excessively heavy or floats and shakes, there is uneven tire wear on one side of the front or rear tires, suspension components have been disassembled and reassembled, or the vehicle's chassis and suspension have been damaged in an accident. Here is some relevant information about wheel alignment: 1. Wheel alignment refers to the installation positions among the wheels, suspension, and steering components. Since a car is a highly precise mechanical device, a well-tuned vehicle requires extremely accurate positioning and parameters for each mechanical component, down to every screw. 2. If the car starts to pull to one side, it may indicate reduced stability in the chassis, necessitating a wheel alignment. Other situations that require a wheel alignment include an off-center steering wheel, severe uneven tire wear (commonly known as tire cupping), or after replacing parts of the steering or suspension systems.

What is the principle of the built-in tire pressure monitoring system in cars?

The principle of the built-in tire pressure monitoring system in cars is that when the car starts moving, the acceleration sensor first sends a signal to the receiver, and then transmits the monitored tire pressure and temperature signals together to the receiver. Once the receiver receives the signal, it immediately displays the information. Here are the relevant details: 1. While the car is in motion, the wireless tire pressure monitor's sensor checks the data every 4 seconds. If no abnormalities are detected, it sends data to the receiver every 20 seconds to conserve power. If an abnormality is detected, it sends data to the receiver every 4 seconds. 2. The tire pressure monitoring system consists of a main unit and sub-units: the main unit is installed inside the car, receiving signals from the sub-units and promptly issuing alarm information. 3. The sub-units are installed on the four wheel hubs, integrated with the valve stems and tightly attached to the hubs. During installation, the original valve stems are usually replaced. The sub-unit modules monitor the tire pressure of each tire and send relevant information to the main unit.
