Does anyone know the difference between gasoline and diesel? What effect does it have on the engine?

Obviously, gasoline engines use gasoline and diesel engines use diesel.

In short, the difference between them is that the compression ratio of gasoline engine is 8~ 12, while that of diesel engine is at least about 16.

Gasoline is easy to atomize, so the oil-gas mixture can be obtained through the throttle valve, and then injected into the cylinder and ignited with a spark plug, while diesel oil is more viscous and more difficult to atomize, so it should be injected into the cylinder when the compressed air in the cylinder reaches the top dead center of the cylinder and atomized with air. Because high pressure produces internal energy, it is compressed and burned.

Because the thermal efficiency of the engine is closely related to the compression ratio, the efficiency of the diesel engine is higher in theory.

The main difference between gasoline and diesel is that diesel has a higher alkane number.
