TGDI stands for Turbocharged Gasoline Direct Injection engine. The following are precautions for engine maintenance: Fuel must be clean: High impurity content in fuel can accelerate the wear of the electric fuel pump, reducing its service life. Dirty fuel can also clog the fuel filter and fuel injectors, affecting fuel supply pressure and normal injection volume, thereby diminishing the engine's performance. Correct fuel selection: Engines have high requirements for fuel quality and grade, with even higher demands for electronically fuel-injected engines. For vehicles equipped with catalytic converters and oxygen sensors, only unleaded high-octane gasoline should be used. If leaded gasoline is used, the exhaust catalytic converter will fail after driving more than 400 kilometers, the oxygen sensor will malfunction, and the engine's normal operation will be affected.

Why is the price of the Envision getting cheaper and cheaper?

The reason why the price of the Envision is getting cheaper is that its failure rate is relatively high compared to similar cars. Below is a detailed introduction about the Envision: 1. Overview: The Chinese name for the Buick ENVISION is "Envision." As a new-generation strategic model under General Motors, the Buick Envision's exterior design inherits the essence of the ENVISION Vision concept car. The 2020 Buick Envision not only adopts the latest design language of the Buick SUV family but also optimizes and upgrades its drivetrain and technological configurations. 2. Powertrain: The 2020 Buick Envision offers a 2.0T SIDI direct-injection turbocharged engine paired with a 9-speed HYDRA-MATIC intelligent transmission, as well as a 1.5T SIDI direct-injection turbocharged engine paired with a 7-speed DCG PLUS intelligent dual-clutch transmission. The former delivers a maximum power of 191 kW at 5500 rpm and a peak torque of 400 Nm between 3000-4000 rpm.

What does the tire pressure warning light mean in the 2021 XRV?

The reason why the tire pressure warning light stays on in the 2021 XRV is due to abnormal tire conditions. Causes of abnormal tire conditions: Abnormal tire pressure: Generally, the warning light will come on if the pressure is below 1.8 bar or above 3.0 bar. In this case, a tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the tire pressure monitoring system will still record the previous data, causing the tire pressure monitoring indicator light to stay on. Simply performing a tire pressure reset will resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which is directly installed inside the tire and connected to the tire inflation valve, is used to monitor tire pressure. If the sensor is damaged due to impact while driving, the tire pressure warning light will also come on. For sensor damage issues, the only solution is to replace it with a new part. The tire pressure monitoring indicator is a yellow symbol—an irregular circle with no stamp on top, four small spikes at the bottom, and an exclamation mark inside. The illumination of the tire pressure monitoring indicator indicates abnormal tire pressure.

What are the reasons why the Audi Q2 cannot play music after connecting to Bluetooth?

Audi Q2 cannot play music after connecting to Bluetooth: causes and solutions: 1. The phone is not connected to the car's Bluetooth: The solution is to re-pair the devices. First, turn off the car's Bluetooth, then press and hold the multifunction button on the car's Bluetooth to activate pairing mode. Restart the phone to clear previous Bluetooth information and search for Bluetooth again. 2. The phone's media volume is set to the lowest level: The solution is to ensure the car's Bluetooth is properly connected to the phone, then go to the phone's settings, enter the sound options, and increase the media volume. 3. The car's audio system is muted: The solution is to turn on the car's audio system sound. 4. The phone's media audio is not turned off, causing signal interference with Bluetooth functionality: Solution: First, enter the phone's Bluetooth settings interface, where there are two options: phone audio and media audio. After connecting to the car's Bluetooth, both options are enabled by default. We need to turn off the media audio while keeping the phone audio enabled. This ensures that Bluetooth calls, car music playback (or radio), and phone navigation voice announcements can function without interfering with each other.

What is the reason for the rough idle when starting a cold GL8?

GL8 rough idle when starting cold reasons: 1. Uneven working conditions of each cylinder: After prolonged use, the spark plugs in the car can cause the gap during ignition to become uneven, which reduces the power of the cylinders in the engine. This leads to unstable idle, shaking, and vibration during cold starts. We can replace the spark plugs to fix this issue. Long-term use of the engine can also cause the distance between each cylinder liner and piston to become uneven, reducing the car's power during startup and resulting in unstable idle. 2. Low engine temperature: This situation is very common in winter. During a cold start, the temperature of the car's internal parts is similar to the outside temperature. At this time, ignition can cause unstable idle and body shaking due to the engine's low temperature and insufficient power. Therefore, in winter, we should try to park the vehicle in a garage, as the garage temperature is higher than outside, which can help alleviate the issue of vehicle shaking and unstable idle. 3. Incomplete combustion of gasoline: Incomplete combustion of gasoline during a cold start indicates insufficient engine power, leading to vehicle shaking. Therefore, after starting the vehicle, we should not rush to ignite it immediately. Instead, wait for a while to allow the engine to build up sufficient power, ensuring complete combustion of gasoline and preventing this issue from occurring.

Where are NGK spark plugs produced?

NGK spark plugs are produced in Japan. Here is some information about NGK spark plugs: 1. Material: NGK uses high-alumina ceramic as the insulator, which provides excellent insulation at high temperatures and ensures reliable spark generation. 2. Advantages: They offer superior thermal conductivity, preventing overheating. They also exhibit strong resistance to thermal shock (rapid heating and cooling) and high mechanical strength. The precise construction ensures excellent airtightness, as special powder is used to bond the insulator and the metal shell, making the structure robust.
