Which product is commonly used as a fuel for cars?

• A. Gasoline
• B. Kerosene
• C. Diesel
• D. Bitumen

Answer: (A)

Fuel choice for cars depends on the type of engine and how the fuel ignites inside the cylinder. Most passenger cars use spark-ignition engines that burn a gasoline–air mixture sparked by a spark plug. Gasoline is refined to vaporize readily and to have the right octane rating, allowing smooth, controlled combustion at typical engine compression. Kerosene is heavier and has a higher flash point, so it isn’t suited for these engines. Diesel fuels are designed for compression-ignition engines and have different properties, powering a different class of engines. Bitumen is a heavy material used for paving, not for combustion in engines. So gasoline is the common fuel for cars.
