How Many Kilometers Can One Liter of 92 Gasoline Drive?

[Rodrigues]

One liter of 92 gasoline can drive 10 kilometers to 15 kilometers. If driving on general city roads, the fuel consumption is approximately 8 liters per 100 kilometers, meaning one liter of gasoline can drive about 12.5 kilometers. Additionally, this depends on the vehicle condition, road conditions, and the driver's habits. Under normal circumstances, one liter of gasoline can support a 1.6L sedan to drive 10 kilometers to 15 kilometers. Theoretically, the heat contained in one liter of gasoline, divided by overcoming the friction and air resistance of a 1.4-ton car, can drive over 50 kilometers. In reality, the efficiency of internal combustion engines is generally around 35%. Friction in the car's transmission mechanism consumes 20%, while active engine cooling, exhaust heat dissipation, noise and vibration, and emission noise waste another 10%. A comprehensive gasoline utilization rate of about 22% is already quite energy-efficient. Therefore, during steady-speed cruising, one liter of gasoline can only drive 10-15 kilometers, which is related to factors like speed and driving habits. It is generally recommended to use 92 gasoline for engines with a compression ratio below 8.5. For engines with a compression ratio between 8.5-9.5, either 92 or 95 gasoline can be used. For cars with an engine compression ratio above 9.5, 95 gasoline or higher-grade 98 gasoline should be chosen to ensure the combustion environment inside the cylinder matches the engine's requirements.
