What are the engine specifications of the 2018 Superb?

The 1.4T version of the 2018 Superb is equipped with an EA211 engine, with a maximum power of 110 kW and a maximum torque of 250 Nm. The 1.8T version features an EA888 engine, delivering a maximum power of 132 kW and a maximum torque of 300 Nm. The 2.0T low-power version also uses an EA888 engine, producing a maximum power of 137 kW and a maximum torque of 320 Nm. The 2.0T high-power version has a maximum power of 162 kW and a maximum torque of 350 Nm. The engines for the 2018 Superb are manufactured in the Changchun Automobile Economic and Technological Development Zone and are domestically produced. For daily maintenance of the 2018 Superb engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment of the intake and exhaust systems and usage conditions. For diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will deteriorate during use. After a certain mileage, its performance will degrade, leading to various engine issues. To avoid malfunctions, change the oil periodically based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances accumulate in the filter. If the filter becomes clogged and oil cannot pass through, it may rupture the filter or open the safety valve, allowing dirty oil to bypass the filter and return to the lubrication system, accelerating engine wear and increasing internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. Small amounts remain suspended in the oil, while larger amounts precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear. Periodically use a radiator cleaner to flush the radiator. Removing rust and scale not only ensures normal engine operation but also extends the overall lifespan of the radiator and engine.

Do Cars Have a Reserve Fuel Tank?

Cars do have a reserve fuel tank. It is located next to the main fuel tank and is connected to an auxiliary diesel tank. 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 running low, and when it is near F, it indicates sufficient fuel. Methods to open the fuel tank: Mechanical key opening: This is usually found in some rugged off-road vehicles. Nowadays, most family cars do not use mechanical keys to open the fuel tank because it is relatively complicated to operate. In-car switch method: The in-car fuel tank switch is located in different positions depending on the car model. Some are on the floor to the left of the driver's seat, some on the left front door panel or the center console, all marked with a fuel pump symbol. However, it is important to note that the in-car switch can easily lead to the owner forgetting to turn off the engine before refueling, so the owner must remember to turn off the engine before refueling. Press-to-open method: The press-to-open fuel tank door is currently the most convenient method. The owner only needs to park the car, and the fuel attendant can press to open it for refueling. However, when the car is not parked for refueling, the owner must remember to lock the central control, otherwise the fuel tank cap can be opened.

What is the phenomenon of engine seizure in cars?

Engine seizure in a car can cause the engine to suddenly stall and fail to start. The reasons for engine seizure are as follows: Excessively small clearance between piston and cylinder: During the friction process between the piston and cylinder, if the clearance is too small, it can lead to insufficient oil film formation, resulting in dry friction and ultimately causing seizure. When replacing cylinder liners and pistons, it is essential to select pistons and liners from the same group. Before installation, it is best to measure the pistons and cylinder liners using a bore gauge and micrometer to ensure the clearance meets specifications. If a bore gauge and micrometer are unavailable, a feeler gauge can also be used. Measurement method: Insert the feeler gauge blade into the clearance between the cylinder and piston skirt (in the direction perpendicular to the piston pin installation). The ideal condition is when there is slight resistance when pulling the feeler gauge, but it can still be moved freely. Proper clearance and good lubrication will prevent seizure. If the piston ring end gap is too small, it will accelerate wear between the piston rings and cylinder liner, and in severe cases, lead to cylinder scoring or seizure. Therefore, when replacing piston rings, ensure their end gaps comply with specifications. Insufficient lubrication oil: During engine operation, the cylinder liner and piston movement areas primarily rely on oil splashed onto the cylinder walls for lubrication. If the oil pan is low on oil, the amount of oil splashed onto the cylinder walls by the rotating motion of the crankshaft and connecting rod big end will be insufficient, preventing the formation of an oil film. This worsens the working conditions of the piston inside the cylinder, increases temperature, and causes excessive piston expansion, leading to seizure. Therefore, it is necessary to add an appropriate amount of qualified lubrication oil. However, adding too much oil can also result in oil burning issues.

How long do you have to wait to retake the test if you fail the first subject?

You need to wait 10 days to schedule the test. The "Regulations on the Application and Use of Motor Vehicle Driving Licenses" clearly stipulates that for the first subject retake, you can take the test twice on the same day. If you fail the first attempt, you can take a free second attempt. If you still fail the second attempt, the first subject test is terminated. The first subject, also known as the first subject theory test or driver theory test, is part of the motor vehicle driving license assessment. The test content includes driving theory basics, road safety laws and regulations, local regulations, and related knowledge. The test is conducted on a computer, with a time limit of 45 minutes. To pass the first subject test, you need a score of 90 out of 100. The test consists of 100 questions, divided into single-choice and true/false questions, with each question worth 1 point. If you answer 11 questions incorrectly during the test, the system will automatically submit the test and end it. The first subject test content includes: driving license and motor vehicle management regulations; road traffic conditions and regulations; road traffic safety violations and penalties; road traffic accident handling regulations; basic knowledge of motor vehicles; local regulations; knowledge of braking systems and safety devices for large and medium-sized passenger and freight vehicles; specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. First subject test precautions: During the test, students should pay attention to their attire—no slippers are allowed. Electronic devices and bags are not permitted in the test room. Bring your ID card and queue to enter the waiting hall. Observe the precautions and procedures on the large screen, and store personal belongings in a locker before entering the test room. Upon entering the test room, the identity verification area will assign a seat. After finding your seat, begin the test. Ensure the camera is aimed at you and follow test discipline. If you fail the first attempt, you can retake it the same day. If you fail again, you will need to pay to reschedule. After the test, queue to collect your score report and sign it. Failure to sign will render the test invalid. There is no limit to the number of times you can schedule the first subject test. Each subject can be taken once, and if you fail, you can retake it once. If you do not take the retest or fail the retest, the test is terminated, and the applicant must reschedule. For the second and third subjects, there are only five test attempts, and the second and third subject tests must be scheduled at least ten days later. If you fail the third subject's safe and civilized driving knowledge test, the previously passed road driving skills test scores remain valid. There are three subjects in the driving test: the first subject, the second subject, and the third subject. The first subject refers to the road traffic safety laws, regulations, and related knowledge test. The second subject refers to the field driving skills test. The third subject test is divided into two parts: road driving skills and safe and civilized driving knowledge test. The safe and civilized driving knowledge test is conducted after the third subject, so it is commonly referred to as the fourth subject test. However, in official terms (i.e., the Ministry of Public Security's Order No. 123), there is no such thing as a fourth subject.

How to Improve Car Noise?

Improving car noise can be achieved by installing soundproofing materials for the engine and replacing door seals. Here is more relevant information: 1. Install soundproofing cotton: Many parts of the car actually have soundproofing cotton, which is designed to block noise. However, due to cost considerations, car manufacturers do not install soundproofing cotton in all areas. 2. Replace with quieter tires: Car tires generate noise when they rub against the ground, and different tires produce different levels of noise. Therefore, replacing them with quieter tires can solve the tire noise problem at its source.
