What Causes the Zzz Sound When Accelerating?

The reasons for the zzz sound during acceleration: 1. Air intake pipe perforation or leakage: Many modern vehicles use engineering plastics for their intake pipes. When these pipes age, they may develop leaks, causing a zzz sound during acceleration. 2. Excessive or loose valve clearance: Valves can also wear out. When the wear reaches a certain level, the valve clearance becomes too large, and air passing through the valves produces a zzz sound. 3. Dirty engine oil: Engine oil provides lubrication, but when it hasn't been changed for a long time, it accumulates contaminants. Without proper lubrication, the engine can produce unusual noises.

Should You Use 4H or 4L When Climbing Mountains?

When climbing mountains, using 4H is sufficient. Here are the relevant details: 1. Modes: 4L: It refers to four-wheel drive low gear. When driving in this mode, the engine's torque increases, allowing it to handle more complex road conditions. 4H: Refers to four-wheel drive full gear mode. Using this mode while driving instantly enhances the car's power, improves handling, but also increases fuel consumption accordingly. 2. Function: For mountain climbing or off-roading, if the car gets stuck in muddy terrain, the 4L mode can help the vehicle escape.
