Here are the detailed differences between Audi TFSI and Volkswagen TSI: 1. Power aspect: TSI has less power loss compared to FSI, and TSI can achieve greater power with smaller displacement. 2. Technical aspect: The FSI engine is a direct-injection engine that uses stratified fuel combustion technology. Compared to the FSI engine, the TSI engine lacks the stratified combustion function, resulting in lower technical sophistication. 3. Combination aspect: The TFSI engine is a turbocharged fuel direct-injection engine, combining the features of both FSI and TSI engines. The TFSI engine has both turbocharging and stratified combustion, integrating the advantages of FSI and TSI engines.

How many liters of engine oil should be added to a BMW 520?

BMW 520 requires 5L of engine oil, and semi-synthetic oil or above with a viscosity of 5W-40 is most suitable. After filling the engine oil, it is necessary to measure whether the oil level is normal, neither too high nor too low. If the oil level is too high, it may overflow, causing excessive lubrication of the belt. Taking the 2017 BMW 520 Classic as an example, here are some relevant introductions: 1. Body dimensions: The BMW 520 Classic belongs to the mid-to-large-sized car category, with body dimensions of 5055mm in length, 1860mm in width, 1491mm in height, a wheelbase of 3108mm, and a fuel tank capacity of 70L. 2. Power: The BMW 520 Classic is equipped with a 2.0T turbocharged engine, with a maximum power of 135kW and a maximum power speed of 5000rpm.

How is the freight rate for semi-trailers calculated?

Semi-trailer freight is generally charged based on a combination of cargo volume, distance, and weight. The total freight price = distance * standard truck load capacity * (ton/kilometer) price. Industry standards set the ton-kilometer price range between: [0.35~0.6] yuan. Relevant details are as follows: 1. Introduction: Semi-trailers are mainly used to transport large-volume, non-separable oversized cargo, such as excavators, etc. Fence-type trailers are more suitable for transporting perishable goods like vegetables and fruits, while box-type trailers are better suited for bulk cargo and moisture-sensitive valuable goods. 2. Difference: Unlike full trailers, semi-trailers have their axles placed behind the vehicle's center of gravity (when the load is evenly distributed) and are equipped with a coupling device that transmits horizontal or vertical forces to the tractor. Generally, full trailers have two axles, while semi-trailers have one. A semi-trailer refers to a vehicle that has no power of its own and shares the load with the main vehicle, relying on the semi-trailer for traction.

What does the yellow exclamation mark on the Haval H6 dashboard mean?

When a yellow exclamation mark appears on the car dashboard, there are four possible scenarios: general faults, automatic transmission faults, abnormal tire pressure, and lighting faults. Below is a detailed analysis of these four situations: General Faults: A triangle with an exclamation mark inside indicates that the car's general performance, components, or functions have malfunctioned. This could include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, engine oil pressure sensor failure, etc. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating that the transmission has a fault or the transmission lubricant is below the normal range. The transmission oil should be replaced promptly. Abnormal Tire Pressure: A horizontal line under a bracket with an exclamation mark in the middle represents the tire pressure monitoring warning light. This light will illuminate when the car's tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling that a car light has malfunctioned. Solution: Visit a 4S shop as soon as possible for inspection and repair, or conduct a self-check, focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue. There is also a red exclamation mark inside a circle with a bracket, which represents a warning for the braking system. This mainly includes braking system failure and low brake fluid level. The braking system should be inspected immediately to avoid accidents.

Is it necessary to stick the annual inspection label on the car window?

Vehicle annual inspection labels do not need to be affixed. Vehicle Annual Inspection: Annual vehicle inspection is a mandatory test for all vehicles with official license plates and registration certificates. It is primarily used to eliminate potential safety hazards and encourage vehicle maintenance and upkeep. Electronic Annual Inspection Certificate: With technological advancements and digitalization, the previous paper-based motor vehicle inspection compliance labels have evolved into electronic certificates, achieving nationwide comprehensive application. Therefore, vehicle owners no longer need to affix paper labels on the front windshield of their vehicles. For vehicles that have already obtained the electronic inspection certificate, there is no need to display a paper label. If a vehicle owner has obtained the electronic motor vehicle inspection certificate, they can simply present the electronic certificate during traffic police checks on the road, which is equally recognized as the paper certificate.
