What Type of Gasoline Should a Bora Use?

The Bora should use 92-octane gasoline, as recommended in the vehicle's official user manual. In addition to checking the appropriate gasoline grade in the user manual, you can also find this information on the fuel tank cap, which is usually labeled. Typically, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92-octane gasoline, while those with a ratio between 10.0-11.5 should use 95-octane gasoline. If the compression ratio is even higher, 98-octane gasoline is recommended. However, with the use of new technologies, the compression ratio alone cannot determine the appropriate gasoline grade. High compression ratios can also be adjusted to use lower-octane gasoline due to other influencing factors such as ignition timing, turbocharging technology, and Atkinson cycle technology. Generally, the higher the gasoline grade, the higher the octane number and the better the anti-knock performance. 92-octane gasoline contains 92% isooctane and 8% n-heptane, while 95-octane gasoline contains 95% isooctane and 5% n-heptane. If you occasionally use the wrong gasoline grade in your Bora, simply switch back to the correct grade after using it up. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower-octane gasoline, using higher-octane gasoline will not cause damage, but the increased octane number can alter the fuel's ignition point, leading to delayed combustion in the engine. This results in reduced engine performance and thermal efficiency, with the practical effect being poorer power output. For vehicles recommended to use higher-octane gasoline, using lower-octane gasoline can cause engine knocking. The significantly lower octane number reduces the fuel's ignition point, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance will arise during the upward stroke. This resistance makes the engine run very unstably. Mild knocking may only increase noise without obvious engine damage, but severe knocking indicates serious engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, potentially leading to cylinder scoring in severe cases.

Where is the Excelle produced?

The Excelle is produced in Shanghai, with body dimensions of 4419mm in length, 1814mm in width, and 1487mm in height, and a wheelbase of 2685mm. The vehicle features the new family-style winged chrome grille, giving the front fascia a sharper and more robust appearance. The combination of black piano vertical grille and high-gloss chrome winged grille focuses the visual center of the front on the emblem, while the winged grille extends horizontally to the headlights on both sides, enhancing the horizontal visual effect and overall cohesion of the front. The car is also equipped with a newly designed 16-inch dual five-spoke luxury two-tone aluminum alloy wheel, with dark coating and precision-machined bright surface treatment, creating a more three-dimensional and layered visual effect. The lightweight and high-rigidity wheel design provides drivers with an excellent handling experience.

How to Determine the Direction of a Check Valve Icon?

Methods to determine the direction of a check valve icon: A check valve is a valve that allows flow in one direction and closes in the opposite direction, preventing the reverse flow of hydraulic oil. In the check valve symbol, the side with the ball is the inlet, and the opposite side is the outlet. The check valve allows fluid to flow only from the inlet to the outlet, preventing the medium from flowing back, hence it is commonly known as a check valve. It is used in hydraulic systems to prevent reverse flow of oil or in pneumatic systems to prevent the reverse flow of compressed air. Check valves come in two types: straight-through and right-angle. Straight-through check valves are threaded and installed in pipelines, while right-angle check valves come in three forms: threaded connection, plate connection, and flange connection.

What are the consequences of a broken engine timing belt?

Consequences of a broken engine timing belt: The valves and ignition system cannot operate normally. The pistons will continue to move up and down due to inertia, while the opening and closing of the valves have stopped. In the confined space of the combustion chamber, the pistons are highly likely to collide with the valves, causing the valve pushrods to bend, the piston tops to dent, and even the cylinder head to be punctured. As part of regular maintenance and comprehensive inspections, timing belt maintenance should be included in the periodic maintenance schedule. Neglecting this and failing to regularly inspect and replace a faulty timing belt in time can lead to severe consequences. Unlike the drive belts of auxiliary devices, the timing belt is not easily visible or simple to inspect.

What Does Mercedes-Benz SOS Mean?

Mercedes-Benz SOS refers to a system that activates during major vehicle accidents, typically triggered by events such as severe collisions, rollovers, or falls. Various sensors detect the vehicle's condition, including seatbelt pretensioning and airbag deployment. When the system's pre-set emergency conditions are met, the SOS emergency call system sends a distress signal along with GPS location data to a receiving platform, enabling swift emergency response. Taking the Mercedes-Benz C-Class as an example, its body dimensions are 4581mm in length, 1810mm in width, and 1448mm in height, with a wheelbase of 2760mm.
