The red terminal on a battery is the positive pole, while the black one is the negative pole. The method for connecting battery terminals is as follows: 1. Open the two fastening buttons of the thermal insulation cover; 2. Use a wrench to loosen the fastening nut on the negative terminal; 3. Pry open the fastening block with a flat-head screwdriver; 4. Connect both positive terminals with a red cable; 5. Connect both negative terminals with a black cable. Battery maintenance methods include: 1. Avoid parking the car in open parking lots for extended periods; if long-term parking is necessary, remove and take the battery with you; 2. Avoid repeatedly starting the vehicle without intervals; 3. Start the car periodically to maintain sufficient battery charge; 4. Regularly inspect battery components and connecting wires; 5.

Why does the new Audi car smell so strong?

Reasons for the strong odor in new Audi cars: Interior decoration materials: The odor mainly comes from the interior decoration materials of the new car, such as leather seats, plastic accessories, newly added floor mats, seat covers, and other items. These decoration materials release harmful substances like formaldehyde, many of which contain unpleasant and irritating smells that are difficult to remove in a short time. Untimely garbage disposal: Another reason for the odor in new cars is the untimely disposal of garbage inside the car, especially during hot summers. If food scraps, snacks, or other garbage are not cleaned up promptly, they can easily become moldy and spoil. It is important to regularly clean items like car carpets and woolen mats, as these can develop odors if left uncleaned for a long time.

What is the horsepower equivalent of an engine with 132 power?

An engine with 132 power is approximately 180 horsepower. Engine Power: Refers to the rate at which the engine performs work. The engine's power is not equal to the vehicle's power, as there are intermediate losses in mechanical transmission. Additionally, safety considerations that lead to thicker and heavier vehicle body designs can also result in engine power loss. Therefore, a vehicle with a small-displacement engine is not necessarily slower or inferior in performance compared to one with a high-power engine. Mechanical Loss Power: The work done by the engine per unit time is called the engine's power. Corresponding to indicated work and effective work, it is referred to as indicated power and effective power (output power), respectively. The difference between these two is called mechanical loss power.

How to Determine if a Vehicle is New When Taking Delivery?

Common methods include checking the mileage or the production date. A mileage between 10-30 kilometers is considered normal, and a production date within three months is also typical. Below is a detailed introduction to specific methods for determining if a vehicle is new: 1. Vehicle identification plate: The identification plate is located on the engine compartment wall or the front door frame. Check the production date on the plate; if it is within three months, the vehicle is considered a normal new car. 2. Exhaust pipe: Inspect the inner wall of the exhaust pipe to see if it has turned black. If a layer of black residue can be felt, it indicates the vehicle's mileage is slightly higher than the normal range. 3. Tires: New tires have small, noticeable bristles, also known as tire hairs. These bristles are usually worn off after the vehicle has been driven 50 kilometers or more.
