Why Diesel?

I'm not going to tell you that all diesel vehicles are better than gas but my goal is to try and make diesel simpler so you can make an informed decision on buying your next vehicle.

To understand why a diesel vehicle would be the right decision for your next vehicle you will have to understand the differences between a gasoline and diesel engine. The major difference between the two is the way the fuel is ignited. A gasoline engine uses a spark plug to ignite the fuel/air mixture entering the combustion chamber, whereas a diesel ignites the fuel/air mixture by using the natural compression/heat the engine produces. The major difference between a gasoline and diesel vehicle is their compression ratios. A typical pump gas engine will have a compression ratio of 9:1 where diesel engines are closer to 19:1.
