What is the fuel tank capacity of the Buick Excelle?

2021 Buick Excelle has a total of 4 models, all with a fuel tank capacity of 44 liters. The 2021 Buick Excelle is equipped with either a 1.3-liter turbocharged engine or a 1.5-liter naturally aspirated engine, with an automatic transmission (AT), and all models feature front-wheel drive. In the same class, the 2022 Nissan Sylphy Classic 1.6XE manual comfort version has a fuel tank capacity of 50 liters, and the 2021 Ford Focus Sedan 1.5L manual version has a fuel tank capacity of 53 liters. During actual refueling, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity marked by car manufacturers is the volume from the bottom of the tank to the safe limit, and there is still some space from the safe limit to the tank opening. This space is designed to ensure that the fuel in the tank can expand when the temperature rises without overflowing the tank's safety space. If the fuel is filled up to the tank opening during refueling, the actual refueling amount may be larger than the calibrated tank capacity. If the owner wants to know the remaining fuel level, they can observe the fuel gauge on the right side of the dashboard, which is marked with E and F. When the pointer is close to E, it means the fuel is almost empty, and when it is close to F, it means the fuel is sufficient.

What is the difference between sweeping the line and crossing the line?

Crossing the line refers to a vehicle's wheels running over traffic marking lines while driving, whereas sweeping the line means the wheels go beyond the traffic marking lines. Below is relevant information about road traffic signs and markings: 1. Introduction: Road traffic signs and markings are traffic facilities set up on roads using specified graphics, symbols, text, lines, vertical markings, raised pavement markers, etc., to indicate specific management content and behavioral rules. 2. Classification: Road traffic signs are divided into two main categories: primary signs and auxiliary signs; road traffic markings can be categorized by their setup into longitudinal markings, transverse markings, and other markings. Road traffic markings can also be classified by function into indicative markings, prohibitive markings, and warning markings.

What are the reasons for the engine warning light in Volkswagen CC?

There are mainly 7 reasons for the engine warning light in Volkswagen CC: Sensor failure: The sensors mentioned here include coolant temperature, crankshaft position, air flow, intake temperature, oxygen sensor, etc. When these sensors are damaged, have poor contact, or signal interruption, the car's ECU cannot accurately obtain engine data, which will trigger the engine warning light. Fuel quality issues: If fuel and engine oil are not added according to the manufacturer's requirements, it may cause engine wear and trigger the warning light. Poor combustion of air-fuel mixture: Poor combustion can lead to engine carbon buildup or knocking. When detected by the oxygen sensor and reported to the ECU, the warning light will illuminate as a warning. Spark plug failure, ignition coil failure, fuel pump failure, and clogged fuel lines can all cause poor combustion of the air-fuel mixture. Turbocharging issues: Intake turbocharging pipes and turbochargers can also cause the engine warning light to illuminate. The most common issue is turbocharger damage, accompanied by symptoms such as oil leakage, excessive oil consumption, reduced power, metal noises, and blue or black smoke from the exhaust pipe. Intake issues: If there is a problem with the car's intake, it may cause engine pipe blockage, and in severe cases, trigger the engine warning light. A dirty air filter that is not cleaned regularly can lead to intake problems. Exhaust issues: Exhaust faults can also trigger the engine warning light. Faults in the rear oxygen sensor, catalytic converter, exhaust camshaft, and bearings are common causes of exhaust problems, with the catalytic converter being the most frequent. Using leaded gasoline, lead or silicon-based lubricant additives, physical damage to the catalytic converter, or fuel system faults can easily cause catalytic converter failure. Anti-theft system failure: If the car's electronic anti-theft system malfunctions or the anti-theft controller does not match the engine electronic controller, the anti-theft system can prevent the engine from operating normally and trigger the engine warning light. If the engine warning light is on, follow these steps: First, check if the engine is running normally, such as whether there is shaking or black smoke. If so, avoid restarting the engine. Note: Do not restart the engine if the red warning light is on. If the engine can start, turn it off for 5-10 minutes, then without pressing the brake, press the start button once or turn the key halfway to the 'on' position without pressing the clutch. The car will enter self-check mode after powering on. Wait 5-10 seconds to see if the warning light turns off. If the warning light remains on, visit a service station as soon as possible. The service station can use a portable diagnostic tool to read the fault code, identify the issue, and perform targeted repairs.

What is TFSI?

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.

Is It Worth Repairing a Fully Submerged Car?

Repairing a fully submerged car is indeed meaningful. Here are the impacts of a water-damaged car: 1. Musty Odor: A water-damaged car refers to a situation where water has entered the cabin, submerging the chassis, floor, and even the engine. The vehicle contains a large amount of sponge, fireproof cotton, insulation cotton, and other fabric materials in the interior and flooring, which are highly absorbent. If these materials are not replaced and only dried, the internal moisture may not be completely eliminated, leading to a strong musty odor during hot summers. This odor can sometimes be harmful to health. 2. Engine: The electronic modules related to the engine are highly prone to short circuits. The vehicle's control computer, akin to the brain of the car, is usually located in the engine compartment with minimal dust protection. After being submerged in water, the central computer and wiring in the car are highly susceptible to short circuits. Issues with these modules can range from minor functional failures to severe vehicle damage or even fire caused by short circuits.
