The difference between 92 and 95 gasoline lies in their iso-octane content: 92 gasoline consists of 92% iso-octane and 8% n-heptane, while 95 gasoline consists of 95% iso-octane and 5% n-heptane. 95 gasoline has a higher iso-octane content, providing better anti-knock performance. Different anti-knock properties are suitable for engines with different compression ratios. High-compression ratio engines require 95 gasoline, while low-compression ratio engines can use 92 gasoline. Gasoline appears as a transparent liquid, is flammable, and is primarily used as fuel for spark-ignition internal combustion engines in cars.

How to Clean Asphalt Wrapped Around Car Tires?

To clean asphalt from tires, you can use the following methods: 1. Apply gasoline, kerosene, or engine oil to the contaminated area, wait for it to dissolve, and then wipe it off easily. 2. Use turpentine or benzene solution to rub the area, then scrub with soapy water and rinse with clean water. 3. Use a tar remover, softening and wiping simultaneously to avoid corroding the tire. Below is some related information about tires: 1. The main functions of tires include dry grip, hydroplaning resistance, providing comfort, reducing driving noise, impact resistance, wet grip, load-bearing capacity, handling performance, average wear, and mileage. 2. The tread mainly contacts the ground, while the shoulder and sidewalls provide support, and the bead seals with the wheel rim. 3. The internal structure of a tire consists of multiple layers of different materials, including the tread pattern, overlay, steel belt layer, stress-absorbing rubber strip, carcass ply layer, and inner liner.

What is the torque standard for spark plugs?

Installation torque for spark plugs is 25-30 N/m. For 12-thread models, the torque is 20-25 N/m, while 14-thread models require 25-30 N/m. Here are precautions for DIY spark plug replacement: 1. Choose spark plugs with correct specifications for your vehicle model. 2. Use professional tools for removal and installation. 3. Apply proper tools and techniques during removal - never use excessive force to avoid thread stripping or breakage inside the cylinder. Spark plugs (spark-plugs), commonly called ignition plugs, function by discharging high-voltage pulses from ignition coils to create an electric arc between electrodes, igniting the air-fuel mixture in the combustion chamber.

What is a Negative Pressure Ambulance?

Negative pressure ambulance, also known as a protective ambulance, differs from regular ambulances primarily in its ability to provide "negative pressure isolation." It is mainly used for the safe isolation and transportation of patients with major infectious diseases. Below is how a negative pressure ambulance works: 1. The air pressure inside the vehicle is lower than the atmospheric pressure outside, allowing air to flow only from the outside to the inside. The air inside is sterilized before being discharged, creating a fixed air flow field within the negative pressure compartment. Air flows from the clean area to the infected source area, with the air pressure inside the negative pressure compartment ranging between -10Pa to -120Pa, minimizing dead zones and vortexes in the airflow. 2. In terms of airflow control inside the vehicle, clean air enters from the top and is discharged from the bottom, ensuring that the air at the medical staff's head level remains clean and sterile, while the air around the patient's lying area gets contaminated and is expelled outside the vehicle through exhaust and filtration systems.

Is it acceptable to add fuel before adding fuel additive?

The correct sequence for adding fuel additive is to add the fuel additive first before refueling. This allows the additive to mix thoroughly with the fuel under the impact of fuel injection, achieving optimal performance. Precautions for using fuel additives include: 1. Always purchase branded fuel additives and avoid randomly using products recommended by repair shops; 2. New vehicles should not rush to use fuel additives; 3. Do not rely solely on fuel additives to clean engine carbon deposits. The purpose of fuel additives is to address carbon deposit issues in fuel injection systems, quickly restore optimal engine performance, compensate for certain deficiencies in gasoline properties, and enhance gasoline characteristics such as improved atomization, reduced wear, engine protection, and lower emissions.
