Is it okay to refuel only when the fuel gauge reaches the red line?

It is conservatively estimated that when the fuel gauge reaches the red line, most cars can still run at least 15-20 kilometers, varying by model, with some cars capable of running up to 30 kilometers. However, it is not recommended as reaching the red line is not good for the fuel pump's cooling. Below is additional information: 1. Fuel Gauge: The fuel gauge is used to indicate the amount of fuel remaining in the car's fuel tank. It can be either a pointer or a digital display. The fuel gauge consists of a fuel level indicator with a voltage regulator and a fuel level sensor. The low fuel warning device alerts the driver when the fuel in the tank falls below a certain level. 2. Refueling Tips: It is advisable to use high-quality fuel to extend the engine's lifespan; also, avoid overfilling the tank, as it can increase fuel consumption and may lead to spillage, causing unnecessary trouble.

First, check the warranty manual to see if the part you are claiming for is still under warranty. Take the car to a 4S shop for inspection to determine if a claim is necessary. The 4S shop will place an order for the part, which usually arrives in about three days. The 4S shop typically keeps the claim form for themselves, but it is recommended that the car owner also keeps a copy of the claim form or the order form.

What is the compression ratio of the Bestune T77 gasoline engine?

The compression ratio of the Bestune T77 gasoline engine is 11.5. To illustrate the technical parameters of an engine, one can generally use the magnitude of power and torque as indicators. However, there are many factors that influence the output of power and torque, one of the key factors being the engine's compression ratio. Below is more information about the compression ratio of the Bestune T77 gasoline engine: 1. The compression ratio indicates the degree to which the gas in the cylinder is compressed when the piston moves from the bottom dead center to the top dead center. 2. During the operation of an internal combustion engine, as the amount of air and fuel in the cylinder decreases, the ignition of the engine tends to become irregular. Conversely, as the fuel-air mixture increases, it becomes more prone to knocking, thus limiting efficiency. As one of the important parameters that can influence factors such as torque, fuel economy, and emission indicators, the compression ratio is key to solving this issue. Therefore, selecting an appropriate compression ratio to achieve a balance among these parameters is a crucial method for enhancing the performance of internal combustion engines. 3. When a gasoline engine is running, it typically draws in a mixture of gasoline and air. During the compression process, as the piston moves upward, it not only compresses the mixture to reduce its volume but also generates phenomena such as swirl and turbulence.

How to Choose the Right Car for Yourself?

Purchase the vehicle with the best cost-performance ratio or the one you most desire within your budget. It's best not to choose the same type as your existing car. If you have a sedan, buy an SUV; if you have an SUV, buy a sedan. If your first car is a fuel-powered vehicle, you might consider a pure electric vehicle for your second car, as pure electric vehicles excel in both performance and usage costs.

First, check if the display screen is damaged. If the display on the screen appears normal, then the issue is not with the display screen. Inspect each connector one by one. If there is poor contact in a connector, there may be a gap. If you find a poorly connected wire connector, you can directly remove it. Press the screen switch continuously to force a restart. If the above methods do not resolve the issue, you will need to visit a 4S shop for repairs.
