What Causes the Noise in Car Window Regulators?

The noise in car window regulators may be caused by aging window seals or abnormal sounds from the window lifting mechanism. There are sealing strips at the bottom of the door windows. If these strips age, the friction between the strips and the window increases, leading to noise when raising or lowering the window. The car body has many sealing strips, and these rubber components can deteriorate over time. When maintaining your car, attention should be paid to the care of these rubber parts. If the sealing strips are no longer effective, they should be replaced promptly, as poor sealing may allow rainwater to leak into the car during rain.

What lights should be used when passing through an intersection at night?

When passing through an intersection at night, you should alternately use high and low beams (flashing more than twice). Additional information: Usage of alternating high and low beams: When passing through sharp curves, slopes, arch bridges, crosswalks, or intersections without traffic lights at night, you should alternately use high and low (headlight) beams (flashing more than twice). Usage of low beams: When driving on well-lit roads, you should use low beams; also, when following another vehicle, low beams should be used to allow the vehicle ahead to observe the situation behind through the rearview mirror; if the distance to an oncoming vehicle is within 150 meters during a meeting situation, you also need to switch from high beams to low beams.

What Compression Ratio Requires 95 Octane Gasoline?

Gasoline vehicles with a compression ratio between 10.0 and 11.5 can use 95 octane gasoline. The engine compression ratio is a key parameter in determining the appropriate gasoline grade, as different compression ratios require varying levels of gasoline anti-knock properties. Generally, engines with a compression ratio below 8.5 should use 90 octane gasoline, those between 8.6 and 9.9 should use 92 octane, and those above 10.0 should use 95 octane. Theoretically, a higher compression ratio demands a higher gasoline octane rating, leading to better fuel utilization and higher engine thermal efficiency. One of the most effective ways to reduce fuel consumption is to increase the engine's compression ratio.
