Gasoline engines compress a mixture of airand fuel, most often mixed in a carburetor or through fuel injection, and ignite that mixture with a spark.Diesel engines compress only air and inject fuel directly into the cylinder, using the heat generated from thecompressed air to light the fuel spontaneously. To generate this heat, the air in diesel engines must becompressed at a much higher ratio than that of a gasoline engine. This higher compression ratio leads to betterfuel efficiency.

Diesel fuel has a higher energy density than gasoline. So you need a smaller quantity of diesel fuel to get the same bang (literally).

I'm not sure if this is why but I believe gasoline burns a lot hotter than diesel therefore using more energy to travel the same distance.
