What are the reasons for the inability to increase vehicle speed?

1 Answers

The reasons for the inability to increase vehicle speed are as follows: 1. Fuel supply system failure: The main power source for car acceleration is the engine, which operates by burning fuel. Therefore, if there is an issue with the fuel supply system, the vehicle speed will naturally fail to increase as required during rapid acceleration. 2. Failure to control fuel pressure, fuel injection quantity, or ignition timing as required: During rapid acceleration of a vehicle, fuel pressure, fuel injection quantity, and ignition timing are all critical factors. If these three aspects do not meet specifications, it is highly likely that the vehicle speed will not increase. 3. Problems with spark plugs and high-voltage wires: Spark plugs and high-voltage wires are important components of a car. The main function of spark plugs is to generate sparks to ignite the mixed gas in the cylinder, thereby increasing the vehicle speed. Therefore, when there are issues with spark plugs and high-voltage wires, attempting rapid acceleration may result in the vehicle speed failing to increase.

How to Check If the Car Battery Has Power

There are several methods to check if the vehicle battery has power: 1. Feel the feedback when starting the car: If you feel that starting the car is very difficult, it is likely due to insufficient battery power. But don't worry too much, as normal driving for one to two hours can restore the battery to normal power levels. 2. Check the battery warning light: If this light stays on, it indicates that the car battery is running low and needs to be charged promptly. 3. Press the car horn directly: If the horn is not as loud as before, it is likely caused by insufficient battery power. Additionally, the car headlights may also be affected, resulting in dimmer light.

How to Pay for Temporary License Plates in Unmanned Parking Lots?

Temporary license plates entering unmanned parking lots will be automatically recognized by the parking fee system. Upon exit, payment can be made manually or through self-service.

What is the shelf life of engine oil after opening?

The shelf life of opened engine oil is about one year. Here are the methods for storing opened engine oil: 1. Storage environment for the engine oil bottle: It must be clean and dry, ensuring no sunlight exposure to prevent oxidation reactions in the oil. 2. After opening the engine oil: It must be sealed immediately. After completing car maintenance, a clean plastic film should be wrapped around the bottle mouth, and the cap should be tightened. 3. When adding the remaining oil from the last maintenance: Do not pour all of it into the engine; keep a portion. Generally, after long-term storage, there might be trace amounts of water at the bottom of the oil bottle. Adding this to the engine could have adverse effects and impact engine performance.

Why is NIO so expensive?

Here are the reasons why NIO cars are expensive: 1. Platform: The ET7 is based on NIO's second-generation electric drive platform, featuring a front permanent magnet + rear induction motor combination. It comes standard with intelligent air suspension and dynamic damping control. The 4D intelligent body control system, utilizing high-definition maps and high-precision sensors, can anticipate road bumps in advance and actively adjust the suspension. 2. Interior: The NIO ET7 adopts second-generation digital cockpit technology. For autonomous driving, it uses Qualcomm's third-generation digital cockpit computing platform, supporting 5G, V2X, Bluetooth 5.2, Wi-Fi 6, UWB, and other vehicle mobile internet and communication capabilities. 3. Battery: The top configuration uses a 150 kWh battery, with a maximum range of 1,000 kilometers. All of these are 'new' technologies, so the cost is inherent, making it impossible for NIO to be cheap even if they wanted to.
