min refers to minimum, ron refers to octane number, and roz refers to the 91 gasoline grade. The following is a related introduction to gasoline octane number: 1. Definition: A numerical indicator that measures the ability of gasoline to resist knocking combustion in the cylinder. A higher value indicates better anti-knock performance. Gasoline with a higher octane number has better anti-knock properties and higher quality. 2. Flame propagation speed during combustion: The normal flame propagation speed of gasoline in the cylinder is 10m/s to 20m/s, while during knocking combustion, it can reach 1500m/s to 2000m/s. The latter can cause a sharp rise in cylinder temperature, incomplete combustion of gasoline, severe machine vibration, resulting in reduced power output and damage to machine parts.

Can a Mercedes-Benz be powered on without ignition?

Mercedes-Benz can be powered on without ignition. Methods to power on without ignition: When the engine is off, press and hold the start button for 3 seconds without stepping on the brake, or press the ignition button twice to turn it on. For key-type ignition, turn the key from the LOCK position to the ACC or ON position (ACC provides partial power, ON provides full power), as long as it is not turned to the START position. Precautions for powering on without ignition: Avoid prolonged use of the battery power and do not turn on high-power devices like headlights, as this may drain the battery and prevent normal engine startup, or even shorten the battery lifespan. When performing vehicle maintenance, always disconnect the power to prevent short circuits or accidental ignition.

What Causes No Airflow in the First Three Gears of a Car's Air Conditioning?

Reasons for no airflow in the first three gears of a car's air conditioning are as follows: 1. Evaporator Box Air Leak: If there is an air leak at the connection between the evaporator box casing and the air duct, the cold air that should be released from the air conditioning vents continuously leaks from the gap, resulting in reduced airflow from the vents. 2. Air Filter: The air filter is located at the intake of the blower. All cold or warm air blown by the car's air conditioning must pass through the air filter. However, the air filter is prone to accumulating dirt. If the owner does not replace the air filter in time, a large amount of dust can accumulate on the filter, which naturally reduces the airflow passing through it. 3. Poor Sealing of Air Ducts: The air conditioning vents are connected to the blower via additional air ducts. If the sealing of these ducts deteriorates, air leakage occurs, reducing the airflow from the vents.

What are the consequences of not signing after the driving test (Subject 3)?

Not signing after the driving test (Subject 3) has no impact, and you can complete the signature later. Below are some relevant tips for the Subject 3 test: 1. Follow the voice instructions: Remember not to perform any operations before the voice announcement ends. Always wait until the voice announcement is complete before proceeding to the next step. 2. Pay attention to special zones: In many areas, the voice announcement no longer reminds candidates of special zones such as school areas, bus stops, and crosswalks. However, candidates must perform corresponding deceleration or avoidance operations based on the project signs and road markings. 3. Situations requiring turn signals in Subject 3: Starting, changing lanes, overtaking, turning, making a U-turn, and pulling over. Among these, starting, overtaking, and making a U-turn always require the left turn signal, while pulling over always requires the right turn signal. Do not use the wrong signal.
