Should Transmission Fluid Be Changed When It Turns Black?

What is the purpose of the N gear in an automatic transmission car?

The functions of the N gear in an automatic transmission car are as follows: 1. Temporary parking: If the car needs to stop temporarily, such as waiting for someone, you can shift to N gear (if the stop is prolonged, it is recommended to turn off the engine). 2. Waiting at traffic lights: When waiting at a red light on the road, the vehicle needs to stop until the light turns green. N gear can also be used (to reduce fuel consumption). If the red light is very short, staying in D gear is also acceptable. 3. Towing: When the vehicle needs maintenance or towing for other reasons, it should be shifted to N gear for towing. 4. Parking and starting: N gear can also be flexibly used during parking and starting. For example, starting from N gear and shifting to D gear is much better than starting from P gear, which requires passing through R gear. Of course, the transmission of an automatic car is not that fragile, and starting from either P gear or N gear is actually fine.

Can a photo of the vehicle license replace the original vehicle license?

If you don't have the vehicle license with you, providing a photo or screenshot taken with your phone is invalid because photos can be synthesized. Generally, only real-time updated electronic licenses or paper licenses have legal validity. Legal basis: According to the "Road Traffic Safety Law," driving a motor vehicle on the road requires carrying both the driver's license and the vehicle license. If you fail to carry the vehicle license while driving, once caught, you will be fined, deducted 1 point, and the traffic police department may impound the vehicle, notifying the driver to provide valid documentation. If you provide the driver's license but commit a traffic violation, penalties will be imposed based on the violation and the failure to carry the driver's license, with the vehicle returned promptly. If you cannot provide the driver's license, you will be penalized for driving without a license. Applying for an electronic license: If you don't have the vehicle license with you, you can present an electronic license during a traffic police inspection. Many regions now support electronic driver's licenses and vehicle licenses. Drivers can apply for electronic licenses through platforms such as Alipay or local traffic police official WeChat accounts.

Why does a new battery lose one bar of power when accelerating?

New batteries lose one bar of power when accelerating because they have virtual power, so they drop one bar when accelerating. A car battery, also known as a storage battery, is a type of battery that works by converting chemical energy into electrical energy. Typically, what people refer to as a battery is a lead-acid battery, which is mainly made of lead and its oxides, with the electrolyte being a sulfuric acid solution. Here are the correct methods to maintain a car battery: 1. Clean the battery regularly: During daily use, pay attention to the battery's condition. Over time, the battery can become covered with dust, powder, grease, and other contaminants. To ensure the battery functions properly, promptly clean the dirt from the battery panel and the positive and negative terminals to extend its lifespan. 2. Avoid long-term parking: If the vehicle is not used for a long time, the battery will discharge on its own. Therefore, even if the car is not in regular use, it is recommended to start it once a week and take it for a short drive to keep the battery fully charged. 3. Regular testing: The lifespan of a vehicle battery is typically 3-4 years. For high-end models with more electronic systems, the battery's lifespan may be shorter. Regular testing of the battery's charge level can help maintain it in optimal working condition.

Why Does a Car Battery Lose Power?

There are several reasons why a car battery may lose power: 1. Prolonged vehicle inactivity: When a vehicle is parked for an extended period, the battery's charge gradually depletes. After long-term parking, the battery may become undercharged, making it unable to start the car. Additionally, if the headlights are left on overnight, the battery may also lose power by morning. 2. Battery reaching its lifespan: Car batteries have a limited lifespan. If not replaced after prolonged use, they may lose power. The battery's condition can be assessed by observing the color indicator inside: green indicates normal, black signifies low voltage, and white means the battery has reached the end of its lifespan and needs replacement. 3. Engine damage: If the engine's belt becomes loose or breaks, it cannot drive the alternator, leading to an open circuit. Broken alternator wires or loose connections can also cause the battery to discharge without recharging. 4. Insufficient battery electrolyte: When the electrolyte level in the battery is low, the battery cannot hold enough charge. During regular use, electrolyte evaporates, so it's essential to check the level periodically. The electrolyte should be between the maximum and minimum marks. 5. Corroded battery terminals: Over time, a car battery's terminals may corrode, leading to power loss. Regular inspection and cleaning of the terminals are necessary to prevent malfunctions and ensure normal vehicle operation.

What Types of Batteries Are Used in New Energy Vehicles?

In terms of types, the batteries currently used in new energy vehicles all belong to chemical batteries. Common ones include five types of power batteries: lead-acid, lithium titanate, lithium cobalt oxide, lithium iron phosphate, nickel-cobalt-manganese, and nickel-cobalt-aluminum. Among the above five types, lithium iron phosphate (LFP) and ternary lithium batteries, which have higher energy density and more stable performance, are the two most widely circulated batteries in the current market and the most widely used mainstream power sources in electric vehicles. In terms of safety, service life, and manufacturing cost, LFP batteries have advantages over ternary lithium batteries, but in terms of energy density, ternary lithium batteries slightly outperform LFP batteries. The energy density of ternary lithium batteries is greater than that of LFP batteries. Energy density is an important indicator for evaluating battery performance. Generally speaking, the higher the energy density, the more electrical energy the battery contains per unit weight or volume, and the longer the driving range it can provide for the vehicle. It is worth noting that due to the increasing demand for battery range, high-nickel NCM811 is a key breakthrough direction in battery development. The main reason for choosing it is that the increase in nickel content promotes the rise in the specific capacity of ternary (nickel-cobalt-manganese) cathode materials, which can further expand the energy density of the battery cell, and the electrical energy storage capacity increases with the increase in energy density.

What does the reborn Jeep model look like?

The 'Jeep' referred to in the reborn model is the Grand Cherokee. This vehicle is a classic model launched by Chrysler, inheriting the authentic lineage of the Jeep brand. As an annual model facelift, this car offers six variants for consumers to choose from. The new vehicle has been optimized in terms of layout and also includes a sports package. The new car is spacious and features a boxy design. From the side view, the lines of the new vehicle are relatively straight, perfectly matching the style of a rugged SUV. At the rear, the new car adopts a brand-new horizontal tail light layout, with the interior suspected to be entirely LED-lit, promising excellent illumination effects. The Grand Cherokee is a mid-to-large luxury SUV under the Jeep brand. It measures 4828mm in length, 1943mm in width, and 1792mm in height, with a wheelbase of 2915mm. The Grand Cherokee has been equipped with two engines: a 3.0-liter naturally aspirated engine and a 3.6-liter naturally aspirated engine. In terms of appearance, the facelifted model maintains the same quality as the new model. The front face features the brand's iconic family-style grille, offering high recognition. The sleek headlights incorporate LED daytime running lights, giving the front face a robust and distinctive look.
