What is the difference between 92 and 95 gasoline?

The difference between 92 and 95 gasoline lies in their composition: 92 gasoline contains approximately 92% isooctane and about 8% n-heptane, while 95 gasoline contains approximately 95% isooctane and about 5% n-heptane. The gasoline octane rating actually represents its anti-knock performance, with higher numbers indicating better anti-knock capability. Gasoline is a colorless to pale yellow, easily flowing liquid at room temperature, difficult to dissolve in water, flammable, with a distillation range of 30 to 220 degrees. Gasoline products can be divided into three main categories based on their use: aviation gasoline, automotive gasoline, and solvent gasoline. The first two are primarily used as fuel for gasoline engines, while solvent gasoline is used in the production of synthetic rubber, paint, grease, fragrances, etc.

Which button to press when the car window is fogged up?

To defog the car window, activate the front windshield defogging mode, then turn on the air conditioning cooling AC switch and lower the temperature. The fog will clear quickly. For automatic air conditioning, simply press the one-touch defrost button, and the remaining operations will be performed automatically. If you want to use the heating system to defog, it is recommended to stop the car first and let the hot air completely dry the moisture inside the car, and the fog will disappear. When the car window is fogged up, press the external circulation button to introduce outside air into the car, which can remove the fog faster. Front windshield defogging works by directing the air conditioning airflow to the front windshield, thereby reducing the temperature difference on both sides of the glass to achieve the defogging effect. When the rear window is fogged up, the water vapor can be evaporated through the rear window heating function, thus achieving the defogging effect.

What are the reasons for the frequent failure of ignition coils?

The reasons for frequent failure of ignition coils: 1. Batch spare parts design and manufacturing issues causing ignition coil damage; 2. The thermal effect of current damaging the coil insulation in the ignition coil; 3. Engine overheating, causing the coil insulating varnish to melt and fail; 4. Excessive spark plug electrode gap, increasing the load on the ignition coil and causing the high-voltage coil to break down, resulting in short circuits or open circuits; 5. High-voltage wire open circuit, making the generated high-voltage electricity have no path to flow, easily causing the high-voltage coil to break down. The ignition coil consists of the primary coil, secondary coil, magnetic core, switching transistor, and other auxiliary components. The primary coil is usually supplied with 12V power by the main relay, the secondary coil discharges to the spark plug for ignition, and the transistor is responsible for switching.

Why can't the manual transmission suddenly shift into gear?

The reasons why the manual transmission suddenly cannot shift into gear are: 1. There is a fault inside the transmission; 2. The clutch is faulty; 3. The gear shifting mechanism connected to the transmission is faulty. Quick solutions for not being able to shift gears: 1. If the lubricating oil inside the transmission is not fully lubricated, start the engine for a while and then try shifting; 2. If the clutch does not fully disengage, try pressing the clutch pedal firmly to the floor to see if you can shift gears; 3. If the difficulty in shifting is caused by wear of the shift push rod, try shifting multiple times to see if it works. If it still doesn't shift, you can only call for rescue. When shifting gears normally, change from 1st gear to 4th gear gradually, and do not skip gears.

What does Aoff mean in a car?

Car Aoff is the button to turn off the auto start-stop function. The auto start-stop function can reduce exhaust emissions and save fuel, and many cars are now equipped with it. Cars equipped with the auto start-stop function have a button to turn it off. Pressing the button can disable the auto start-stop. The auto start-stop off button is a circle with an A inside and "off" below the circle, which means turning off the auto start-stop. For cars with the auto start-stop function, when waiting at a red light, as long as the battery has sufficient power and the engine water temperature reaches the normal temperature, the system will shut down the engine. If the battery power is insufficient, the auto start-stop system will not work. When the auto start-stop system cannot function, the indicator light on the dashboard will flash yellow. If the auto start-stop system is working normally, the indicator light on the dashboard will flash green.
