What Makes Your Diesel Different?

First, let’s take a quick look at what makes your diesel different. In the broadest sense, this kind of engine works the same as a gasoline engine. They’re both considered internal combustion engines. This means that small controlled explosions change fuel into mechanical power that is used to propel the automobile. The difference, however, is how this occurs. The gas combines with air in a gasoline engine before being compressed and ignited in the combustion chamber. In contrast, the air alone is compressed first in a diesel engine. The hot (under extreme compression) air then combines with the diesel fuel for ignition. Therefore, fuel is injected differently depending upon which type of power your vehicle employs. A gasoline engine uses either a carburetor or port injection system, while a diesel sends fuel directly into the cylinder.

Myths You May Have Heard

A lack of understanding sometimes leads to the spread of misinformation. Such is the case with diesel engines. For example, some drivers have often heard that diesel fuel is difficult to find and expensive. This supply chain conversation is a bit skewed. First, diesel fuel is now a staple at most stations. There are, of course, truck stops with rows of pumps dedicated to large trucks needing to fill up with diesel fuel, but this power source is now available at the majority of gas stations. Second, all fuel is more expensive than drivers would like it to be. While it may cost a little more than gas, fuel efficiency may equalize the expense. Also, drivers who travel at high altitudes may want to take note of the following. While some claim that there’s no difference in engine performance as you move to higher elevations, this simply isn’t true. Diesel engines have turbochargers that make them perform better at high altitudes. Finally, despite rumors, the quality of the diesel exhaust fluid (DEF) you choose makes a difference. Purchase a good quality treatment that’s appropriate for your vehicle. Your exhaust will be cleaner (a bonus for the environment), and your engine will perform better (a bonus for you).
