It belongs to the auxiliary braking gear. When this gear is engaged, the vehicle will generate a certain dragging effect from the engine when going downhill and releasing the accelerator pedal, which helps brake the vehicle, prevents the braking system from overheating, avoids brake failure, and does not affect the normal acceleration of the vehicle. It has a high utilization rate. The following is a related introduction about new energy: 1. Definition: New Energy-NE: Also known as non-conventional energy. It refers to various forms of energy other than traditional energy sources. These are energy sources that are just beginning to be developed or are being actively researched and awaiting promotion, such as solar energy, geothermal energy, wind energy, ocean energy, biomass energy, and nuclear fusion energy. 2. Characteristics: Abundant resources, generally with renewable characteristics, can be used sustainably by humans. Low energy density, requiring large spaces for development and utilization.

How Long is the Warranty for Volkswagen Car Batteries?

The warranty period for Volkswagen car batteries is one year. If the battery encounters any issues within this period, it can be replaced free of charge. To maintain the battery, please note the following: 1. Avoid parking the car outdoors for extended periods: If the car is to be parked for a long time, remove the battery to prevent freezing damage. 2. Avoid multiple continuous starts: In winter, car engines are harder to start. Each attempt to start the engine should not exceed 5 seconds, with at least a 15-second interval between attempts. If the car still doesn't start after multiple attempts, check other aspects such as the electrical circuit, ignition coil, or fuel system. Continuous starting attempts can cause the battery to over-discharge and burn out. 3. Regularly start the car to charge the battery: Car batteries need frequent charging. If left unused for a long time, they will gradually self-discharge and eventually become unusable. 4. Avoid using the car battery after turning off the engine: Using the battery alone when the engine is not generating power can cause damage to it.

How to Open the Trunk of an Excelle?

For the Buick Excelle, pressing the button on the driver's side door panel can open the trunk. Below are the specific methods to open a car's trunk: 1. Remote Key from Outside the Car: The most common way to open the trunk from outside the car is by using the remote key. Simply press the trunk symbol (a raised car rear) on the car key to open the trunk. Some car models may not have a dedicated trunk button on the remote key; in such cases, pressing the unlock button will also open the trunk. 2. Interior Control Switch: The interior control switch for opening the trunk includes button-type and lever-type. The position of the button-type switch may vary depending on the manufacturer and car model, but it is generally located on the left side of the steering wheel or in the central control area. For example, in the Sagitar, the trunk button is usually located on the door. Some car models do not use a button but a lever, which is typically located on the lower left side of the driver's seat or the lower left side of the steering wheel.

What does intelligent cylinder deactivation technology mean?

The so-called intelligent cylinder deactivation technology refers to a series of "methods" that allow some cylinders to stop working (enter a dormant state) when the engine is operating under medium to low load conditions, while the remaining cylinders continue to function normally. This helps reduce fuel consumption and exhaust emissions. When high load operation is required, all cylinders are activated to ensure there is no perceived lack of power. Below is relevant information: 1. Application of intelligent cylinder deactivation technology: This technology is typically used in multi-cylinder, large-displacement engines such as V8, V10, and V12 engines. The advantage of variable cylinder technology lies in its ability to shut down some cylinders during low-load operation or deceleration, using only the remaining cylinders to reduce fuel consumption. 2. Fuel efficiency of intelligent cylinder deactivation technology: When the vehicle requires high power output, such as during rapid acceleration or climbing, the system automatically engages all cylinders to provide sufficient power. This balances both economy and performance, achieving intelligent power management. Additionally, when some cylinders are deactivated, the system increases the workload of the remaining cylinders, indirectly improving their fuel efficiency and reducing fuel consumption, typically saving around 8% in fuel usage.

How Often Should a Car Battery Be Charged?

How often a car battery should be charged depends mainly on the battery capacity and mileage of the electric vehicle, rather than time. Currently, mainstream pure electric vehicles in China can travel 300-400 kilometers (theoretical value) on a single charge, with some imported models exceeding 500 kilometers. Below are relevant details: 1. Factors affecting mileage: The main factors influencing an electric vehicle's range include battery capacity, driving speed, vehicle power, controller performance, motor performance, vehicle weight and load intensity, riding habits, temperature, battery aging degree, charger quality, and charging duration. The battery is just one of many factors, not the most critical one. 2. Regular charging: Even fully charged batteries require periodic charging, generally under three circumstances: First, start the car and use its own generator to charge, which should be done fully every half month; second, use an external charger to charge, which should be done fully every month; third, charge the car battery, which should be done fully every three months.

Can You Mix Gasoline from Different Gas Stations?

Gasoline from different gas stations and brands can be mixed as long as they have the same octane rating. If the octane ratings are different, even if they are from the same brand, they should not be mixed. Mixing different octane fuels can lead to abnormal combustion, causing engine knocking. Besides damaging the combustion chamber, knocking can directly affect the normal operation of the engine and may even cause severe engine damage. To determine the appropriate fuel grade for your vehicle, you can refer to the car's user manual or check the fuel grade marked on the fuel tank cap. How to handle adding the wrong gasoline: If you add gasoline with a higher octane rating than specified (e.g., using 95 octane when 92 is recommended), simply switch back to the recommended 92 octane after consuming the current fuel. If you add gasoline with a lower octane rating than specified (e.g., using 92 octane when 95 is recommended), you can add a high anti-knock fuel additive. Alternatively, you can drain the fuel tank and refill it with the correct 95 octane gasoline.

Is it illegal to drive with a car trunk unable to close due to cargo?

Driving with a car trunk unable to close due to cargo is, strictly speaking, a violation and thus illegal. An open trunk poses a risk of items falling out, which could become road hazards. Additionally, an open trunk can obstruct the view of drivers behind, compromising their driving safety. However, in practice, traffic police usually do not intervene. Even if caught, the typical reason cited is "mixing passengers with cargo," and the usual response is a verbal warning rather than a penalty. However, transporting hazardous materials can result in fines and demerit points. Relevant laws and regulations: "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" Article 54: The load of a motor vehicle shall not exceed the permitted load capacity specified on the vehicle's registration certificate, and the length and width of the load shall not exceed the dimensions of the vehicle body. The following provisions shall also be observed: 1. For heavy and medium-duty trucks and semi-trailers, the height of the load from the ground shall not exceed 4 meters, and for container transport vehicles, it shall not exceed 4.2 meters; 2. For other motor vehicles carrying cargo, the height of the load from the ground shall not exceed 2.5 meters; 3. For motorcycles, the height of the load from the ground shall not exceed 1.5 meters, and the length shall not exceed the body by 0.2 meters. For two-wheeled motorcycles, the width of the load shall not exceed the handlebars by 0.15 meters on each side; for three-wheeled motorcycles, the width of the load shall not exceed the body; 4. Passenger vehicles, except for external roof racks and built-in luggage compartments, shall not carry cargo. For roof racks on passenger vehicles, the height of the load from the roof shall not exceed 0.5 meters, and the total height from the ground shall not exceed 4 meters.
