What is the compression ratio of the Bora engine?

The compression ratio of the Bora engine is 10.5:1. Engine compression ratio: Refers to the degree to which the engine's mixed gas is compressed, expressed as the ratio of the total cylinder volume before compression to the cylinder volume after compression, which is the ratio of the combustion chamber volume. Compression ratio and gasoline octane rating: The engine compression ratio is the most important parameter in determining the appropriate gasoline octane rating. Academically, there is no very unified standard specifying which octane rating should be used for which compression ratio. Moreover, with the widespread application of knock sensors and automatic adjustment technology for ignition timing, high-compression ratio cars can also use lower octane gasoline. Using the correct gasoline not only increases power but also saves fuel, makes the engine run smoothly and quietly, maintains an appropriate engine temperature, and ensures good lubrication.

What causes the BMW 5 Series to suddenly have difficulty steering at times?

The reasons why the BMW 5 Series sometimes suddenly has difficulty steering include insufficient power steering fluid, low tire pressure, or faults in the steering gear and power steering pump. The specific causes and solutions are as follows: Insufficient power steering fluid: Power steering fluid is a medium oil used in the car's power steering pump, which helps transmit steering force and provides cushioning. When the power steering fluid is insufficient, the steering will feel heavy and stiff. Solution: Regularly replace the power steering fluid. Low tire pressure: Low tire pressure increases the contact area between the tires and the road surface, leading to greater friction and making steering more difficult, resulting in a heavy steering wheel, which is not conducive to driving safety. Solution: Check the tire pressure. Faults in the steering gear or power steering pump: The steering gear and power steering pump are also crucial for car steering. Any faults in these two important components can make steering difficult. Solution: Promptly repair or replace them.
