Here are the functions of an ignition advance device: 1. The ignition advance device appropriately advances the ignition timing without altering the original engine structure, ensuring stable combustion of natural gas and improving engine power when using natural gas. 2. The ignition advance controller enables the combustion of different fuels and automatically adjusts the ignition advance angle, ensuring the engine operates at the optimal ignition advance angle under different speeds. 3. Additionally, without changing the original engine compression ratio and combustion structure, precise control of different ignition advance angles is achieved through microcontroller control based on the position of the switch.

Is the Golf's Transmission Wet or Dry?

The Golf 1.6T model features a wet transmission, while the Golf 1.4T model is equipped with a dry transmission. Below is an introduction to the dry and wet transmissions in Golf vehicles: 1. Working Principle: There is no fundamental difference between dry and wet dual-clutch transmissions; the distinction lies in the cooling method of the dual-clutch friction plates. Compared to traditional manual transmissions, the DSG is more convenient to use because it remains a manual transmission at its core, but incorporates DCT technology to provide automatic performance. 2. Clutch Position: The two sets of clutch plates in a wet clutch are housed in a sealed oil chamber, whereas the friction plates in a dry clutch do not have a sealed oil chamber and rely on air cooling for heat dissipation.

What are the serious defects of the BYD S6?

BYD S6 has the following serious defects: 1. Noticeable noise: When the vehicle is idling, especially when cold, the noise inside the cabin is quite noticeable. To ensure the engine oil is fully and evenly distributed for protection during operation (idling stabilizes at 800 rpm, with instantaneous fuel consumption around 1.4), it takes more than three minutes to warm up the car, which is somewhat lengthy. 2. Overly hard brake discs: The excessive hardness of the brake discs leads to abnormal braking noises. 3. Abnormal noises from certain parts at high RPMs: Some components are not securely connected. 4. Key detection failure: While driving, issues such as the horn not working and turn signals not lighting up may suddenly occur. 5. Limited driver's space: The foot space is cramped, and releasing the clutch quickly can easily cause the left knee to hit the surrounding area.

Will highways be closed due to rain?

Under normal rainy conditions, highways are not closed unless there is extreme weather such as heavy rain or thick fog. In such cases, temporary closures are usually implemented to prevent accidents. Highways are only closed in the event of natural disasters, severe weather conditions like strong winds, typhoons, or heavy snow, or serious multi-vehicle accidents. Below are some precautions for driving on highways during rainy weather: 1. Ensure clear visibility: Before starting the car, the driver should ensure good visibility. Rain can cause the rearview mirrors to become wet and blur the driver's vision. Always wipe the mirrors dry to clearly observe the movement of vehicles behind and react quickly. 2. Check the vehicle's brakes: Before driving, promptly inspect the vehicle's braking system to prevent accidents caused by brake failure due to water ingress. 3. Avoid sudden braking when encountering water: Reduce speed when driving through puddles to prevent splashing water from hitting the windshield and obscuring the driver's view. Do not abruptly brake to avoid water on the highway, and ensure the vehicle's direction of movement does not change significantly.
