What Causes Low Volume in Car Bluetooth?

What is the difference between using 95 and 98 octane gasoline in a Mercedes-Benz E300?

The Mercedes-Benz E300 uses 95 octane gasoline, which is composed of isooctane and n-heptane. Higher octane numbers are not necessarily better; the appropriate gasoline grade should be selected based on the engine's compression ratio. Here is some relevant information: 1. Standard gasoline: Standard gasoline is composed of isooctane and n-heptane. Isooctane has good anti-knock properties, with an octane rating of 100, while n-heptane has poor anti-knock properties and is prone to knocking in gasoline engines, with an octane rating of 0. If the gasoline is labeled as 90 octane, it means that the gasoline has the same anti-knock properties as standard gasoline containing 90% isooctane and 10% n-heptane. 2. Compression ratio: The primary criterion for selecting gasoline grade is the engine's compression ratio, which is also a core energy-saving indicator in modern cars. Engine operation consists of a repetitive cycle of intake, compression, combustion, exhaust, and intake in the cylinders. The compression ratio is the ratio of the cylinder volume when the piston is at its farthest point to when it is at its nearest point in the stroke.

How long does it take to pick up a car after pre-sale?

If the 4S store does not have the car in stock, but the manufacturer has it in stock, plus the transportation process in between, it usually takes about 11 to 12 days to pick up the car. Details to pay attention to when picking up a new car: 1. Vehicle documents: Vehicle documents include the purchase invoice, vehicle certificate of conformity, vehicle consistency certificate, motor vehicle registration certificate, three-guarantee certificate, etc. These documents are very important, and some are necessary for later registration, so they must be complete; otherwise, it will affect the new car registration. 2. Vehicle appearance: Try to park the vehicle in an outdoor area with sufficient light to check whether the paint is uniform and whether there are scratches and wear on the paint surface. 3. Electrical equipment: New cars are generally not allowed to be test-driven, so after starting the car in place, check the engine condition and test the functions of other electrical equipment, including lights, wipers, air conditioning, multimedia, windows, etc.

Which air circulation mode should be used when driving a car?

Automobile air conditioning systems generally have both internal and external circulation switches. When external circulation is activated, the air conditioning draws air from outside the vehicle, while internal circulation recirculates the air inside the cabin. It's recommended to alternate between internal and external circulation modes. Here's additional information: 1. Advantages and disadvantages of internal circulation: Internal circulation enhances air conditioning efficiency by recooling the already cooled indoor air, resulting in better cooling performance. However, prolonged use of internal circulation may degrade the air quality inside the vehicle, potentially causing dizziness or discomfort. 2. External circulation: This mode should be used when the outside air is fresh and of good quality. Additionally, external circulation must be activated for effective defrosting or defogging when using the air conditioning system.

What is the fuel tank capacity of the Trumpchi M8?

There are currently 15 models of the Trumpchi M8 available for sale or soon to be launched. The 2021 Trumpchi M8 has a fuel tank capacity of 65 liters. It comes with a 2.0T engine and offers one transmission option, an automatic. The engine has a maximum power output of 185.0 kW and a maximum horsepower of 252 PS. Among them, the 2018 and 2019 Trumpchi M8 models have a fuel tank capacity of 65 liters, while the 2020 model has a capacity of 68 liters. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the fuel tank capacity specified by the car manufacturer is measured from the bottom of the tank to the safety limit. There is additional space from the safety limit to the tank opening, which is designed to allow for fuel expansion due to temperature increases without causing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked tank capacity. To check the remaining fuel level, owners can observe the fuel gauge on the right side of the dashboard, which is marked with E and F. When the needle is close to E, it indicates low fuel, and when it is near F, it means the fuel level is sufficient.
