Is autohold the same as auto start-stop?

autohold is not the same as auto start-stop. autohold is a derivative function of electronic parking. Traditional handbrakes require manual release when starting on a slope, while the autohold function uses a slope sensor to provide parking force through the controller. When starting, the parking control unit, through sensors such as the clutch distance sensor and accelerator pedal sensor, automatically releases the parking brake when the driving force exceeds the running resistance, allowing the car to start smoothly. Enabling the autohold function activates the corresponding automatic parking function. Even in D or N gear, there is no need to keep the foot on the brake pedal; the car remains stationary. To release the stationary state, simply tap the accelerator pedal.

What type of fuel should an Audi A7 use?

Audi A7 should use 95-octane gasoline. The specific type of fuel required is clearly indicated in the owner's manual of each vehicle. Using higher-octane fuel in a low-compression engine can easily cause carbon buildup in the engine. Conversely, using lower-octane fuel in a high-compression engine may lead to knocking due to insufficient anti-knock properties of the fuel, ultimately causing engine failure. Below is an introduction to the functions of engine oil: Lubrication and Wear Reduction: There is rapid relative sliding between the piston and cylinder, as well as between the main shaft and bearing bush. To prevent excessive wear on parts, an oil film needs to be established between the two sliding surfaces. A sufficiently thick oil film separates the surfaces of the relatively sliding parts, thereby reducing wear. Cooling and Temperature Reduction: Engine oil can carry heat back to the oil tank and dissipate it into the air, helping the radiator cool the engine. High-quality engine oil can carry carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank through circulation, washing away contaminants generated on the working surfaces of components via the flow of lubricating oil.

Can Drum Brakes Modified to Disc Brakes Pass Annual Inspection?

Drum brakes modified to disc brakes can pass annual inspection. Changing drum brakes to disc brakes and filing the modification with the vehicle management office does not affect the inspection. As long as there are no issues with the braking system during the annual inspection, the vehicle will pass smoothly. Disc brakes, also known as hydraulic brakes or oil brakes, are a modern braking system, while drum brakes are a traditional braking method that relies on friction between the brake shoes and the drum to slow down the vehicle. Drum brake shoes are divided into leading shoes and trailing shoes, with the leading shoes capable of self-energizing. Each wheel has two brake shoes, typically in a leading-trailing configuration, but some may have dual leading or dual trailing shoes. Sometimes, the brakes may emit a squealing noise, which comes from the leading shoes. Although they provide strong braking force, they can also cause damage to the brake shoes.

How to Use a Car Spare Tire for Beginners

Methods for beginners to use a car spare tire: 1. Regularly check the spare tire: During routine maintenance or before long-distance trips, inspect the spare tire for wear or cracks. If it has worn down to the indicator line, it should be replaced as soon as possible. 2. Replace expired tires periodically: Tires are rubber products and will age over time, typically with an aging period of about 4 years. 3. Do not use the spare tire for an extended period: Due to its infrequent use, the spare tire has different friction coefficients compared to the other four tires. Additionally, non-full-size spare tires differ in aspect ratio, width, or diameter from regular tires. Prolonged use can adversely affect the vehicle's braking system, steering system, and suspension system, posing safety hazards. It may also cause uneven friction among other tires in the same direction.
