What are the differences between the Mercedes-Benz long wheelbase and standard wheelbase models?

The differences between the Mercedes-Benz long wheelbase and standard wheelbase models include exterior design, body materials, functional configurations, and space size. Exterior design: There is a fundamental difference in design between the domestically produced Mercedes-Benz E-Class long wheelbase version and the imported Mercedes-Benz E-Class standard wheelbase version. The body of the domestically produced long wheelbase version is more elongated, and it features an additional triangular window at the rear side window position. In contrast, the imported standard wheelbase version has a more compact body. Body materials: The domestically produced Mercedes-Benz E-Class long wheelbase version uses steel materials for its body, while the imported standard wheelbase version employs an aluminum body. This results in differences in weight. Additionally, overall, the aluminum body is more fuel-efficient but less stable, whereas the steel body, though more fuel-consuming, offers higher stability. Functional configurations: In terms of configurations, the imported Mercedes-Benz E-Class standard wheelbase version is slightly superior. For instance, the front seats in the imported standard wheelbase version come with three-position memory seats, allowing quick adjustment to a comfortable angle. This feature is not available in the domestically produced long wheelbase version of the same level and requires a higher configuration. Another outstanding feature is the electrically adjustable steering wheel, which is standard across all imported standard wheelbase models but only available in mid-to-high configurations of the domestically produced long wheelbase version. The panoramic camera, a very convenient feature for driving and assisting in driving, is also only available in mid-to-high configurations of the domestically produced long wheelbase version. Space size: The domestically produced Mercedes-Benz E-Class long wheelbase version offers more space. Comparatively, the imported standard wheelbase version is less spacious. The domestically produced long wheelbase version includes a vanity mirror in the rear seats and two cup holders in the front seats, whereas the imported standard wheelbase version only has one cup holder.

Will I be fined if I don't drive with an expired temporary license plate?

Temporary license plates that have expired but are not being used on the road will not result in fines. For new vehicles with expired temporary license plates, you can apply for a new temporary license plate online without resubmitting the required documents. The validity period of a temporary license plate is 15 days, and each vehicle can have up to 3 temporary license plates. It is important to note that the owner can only apply for one temporary license plate at a time and must renew it upon expiration. Regardless of whether the temporary license plate has expired, the owner can register the vehicle at any time, without being restricted by the temporary license plate's validity period. Temporary license plates are issued by the vehicle management department of the public security bureau for newly purchased vehicles before official registration. Two temporary license plates must be affixed: one on the upper right corner of the front windshield inside the vehicle, ensuring it is not covered by the compulsory traffic insurance label, and the other on the upper left corner of the rear windshield inside the vehicle.

What happens if you stuff a steel wool ball into a car's exhaust pipe?

Stuffing a steel wool ball into a car's exhaust pipe can prevent the engine from starting. The exhaust pipe is designed to expel the waste gases produced by engine combustion. If the exhaust pipe is blocked, it will affect the smooth flow of exhaust gases, thereby disrupting the engine's normal operation. A car's exhaust pipe consists of three sections: the front pipe (header), mid-pipe, and tailpipe. The front pipe, also known as the exhaust manifold, can be seen after opening the engine hood. The mid-pipe is the longer tube located under the car's chassis, while the tailpipe is the section near the rear bumper. The exhaust pipe is installed between the engine's exhaust manifold and the muffler, providing flexible connection for the entire exhaust system. This setup helps reduce vibration and noise, facilitates installation, and extends the lifespan of the exhaust and muffler system.

How often should the engine oil be changed for an Audi?

Audi recommends changing the engine oil every six months or 5,000 kilometers. Engine oil plays a crucial role in lubricating and reducing friction in the engine, aiding in cooling, sealing to prevent leaks, preventing rust and corrosion, and providing shock absorption. Taking the Audi A3 as an example: it is a compact car equipped with a 1.4T turbocharged engine, which delivers a maximum torque of 250 Nm and a maximum horsepower of 150 hp, paired with a 7-speed dual-clutch transmission. The front suspension of the Audi A3 features a MacPherson strut independent suspension, while the rear suspension is a multi-link independent suspension. It comes with features such as front seatbelt reminder, tire pressure warning, traction control, brake assist, cruise control, and front and rear radar.

How Often Should a New Car's Engine Be Cleaned?

New cars should have their engines cleaned every 30,000 to 50,000 kilometers. The method for cleaning the engine lubrication system is as follows: 1. Pour the engine cleaning agent directly into the oil filler port; 2. Start the vehicle and let it idle for 10 to 15 minutes; 3. Drain the old oil containing the cleaning agent until the cleaning process is complete; 4. Replace with new oil and oil filter. An engine is a machine that converts other forms of energy into mechanical energy. It was invented in the UK and can refer to either the power-generating device or the entire machine, including the power unit. Engine types include internal combustion engines, external combustion engines, electric motors, and more.

How to Solve the Abnormal Noise of the Oil Pump?

Solutions for abnormal noise in the oil pump: Replace it with a new one. The causes of abnormal noise in the oil pump include: 1. Low insulation between the rotor and stator or friction with the slot wedge; 2. Bearing wear or the presence of sand particles and other foreign objects in the oil. The oil pump is a crucial component in the fuel supply system. Without the gasoline pump, the engine's fuel supply would be compromised, affecting its normal operation. The oil pump is a lightweight and compact pump, categorized into three main types: in-line, distributor, and unit pumps. The gasoline pump is located inside the fuel tank, while some engines with direct injection technology also have a high-pressure oil pump in the engine compartment. The gasoline pump draws fuel from the tank and provides it under pressure. Most common engines use multi-point injection and direct injection.
