How to Check the Oil Level in an Audi S4?

Audi S4's oil level is displayed electronically and can be checked through the MMI system. Here are the detailed steps: 1. Steps to check the oil level in an Audi S4: First, start the vehicle, locate and press the 'car' button on the center console, then use the center console knob to navigate to the oil level option in the MMI menu. Press the knob to display the oil level. 2. The engine is the heart of a car, containing many metal surfaces that move and rub against each other: engine components move at high speeds in harsh environments, with operating temperatures reaching 400°C to 600°C. Only by using qualified lubricating oil can the wear and tear of engine parts be reduced, thereby extending its service life. 3. Oil also aids in cooling: while the engine is running, the oil carries heat back to the oil tank, which then dissipates it into the air, assisting the radiator in cooling the engine. However, the actual cooling is done by the water outside the engine casing.

Where is the car ignition coil located?

The car ignition coil is positioned at the front upper part of the engine. Inside the ignition coil, there are two sets of windings: the primary coil and the secondary coil. The primary coil is wound with approximately 200 to 500 turns of enameled wire about 0.5 to 1 mm in diameter, while the secondary coil is wound with around 15,000 to 25,000 turns of enameled wire about 0.1 mm in diameter. The working principle of the car ignition coil is as follows: 1. When the primary coil is connected to the power source, a strong magnetic field is generated around it as the current increases, and the iron core stores the magnetic energy; 2. When the switching device disconnects the primary coil circuit, the magnetic field of the primary coil rapidly decays, inducing a high voltage in the secondary coil; 3. The faster the magnetic field of the primary coil disappears, the larger the current at the moment of disconnection, and the greater the turns ratio between the two coils, the higher the voltage induced in the secondary coil.

What is the difference between 95 gasoline and 92 gasoline?

The differences between 95 gasoline and 92 gasoline are: 1. Different n-heptane content: 95 gasoline contains 5% n-heptane; 92 gasoline contains 8% n-heptane. 2. Different isooctane content: 95 gasoline contains 95% isooctane; 92 gasoline contains 92% isooctane. Different gasoline grades represent different fuel anti-knock properties. The higher the gasoline grade, the better the anti-knock performance. Gasoline is a volatile, flammable hydrocarbon mixture liquid obtained from petroleum through fractionation, cracking, or pyrolysis. Its characteristics include: volatility, stability, anti-knock properties, corrosiveness, and cleanliness.

Can the Audi A3 use 92 octane gasoline?

Audi A3 cannot use 92 octane gasoline. It is better to use higher octane gasoline for the following reasons: 1. Low octane gasoline will reduce acceleration performance and fuel economy; 2. It may cause knocking and damage the engine. Taking the 2021 Audi A3 Sport Progressive as an example, it is a compact car with body dimensions of 4351mm in length, 1815mm in width, and 1458mm in height, with a wheelbase of 2630mm and a fuel tank capacity of 51 liters. The 2021 Audi A3 Sport Progressive is equipped with a 1.4L turbocharged engine, delivering a maximum horsepower of 150ps and a maximum power speed of 5000 to 6000 rpm.
