When it comes to diesel engines, one of the first things you would immediately notice is that people are much more accustomed to gasoline engines. Indeed, the facts bear this out, especially when you consider that as many as 97% of registered passenger vehicles such as pickup trucks, SUVs, vans and trucks run on gasoline. Of course, if you are going to do any type of work with a diesel engine, it is important to understand how they are different than gasoline engines.

For starters, you need to understand the similarities between a gasoline engine and a diesel performance engine. IN both diesel and gasoline engines, the basic makeup of the engine is the same. They both possess crankshafts, pistons and air coming in and exhaust coming out. What is the main difference then? Consider the following principle:

The difference between a gasoline engine and a diesel engine can be summed up in just one word: turbocharger. Simply put, a diesel engine possesses a turbocharger and a gasoline engine does not. Moreover, this is where things get interesting.

Simply put, a turbocharger is one of the things that gives a diesel engines its power. The turbocharger is responsible for forcing air into the engine. Once the diesel fuel goes into the engine, it forces the combustion to occur. After that, it causes exhaust gasses to leave the engine and then it spins the turbine wheel and it turns the compressor wheel and forces more air into the engine. This is a never-ending process while the diesel motor is on.

Having a thorough understanding of this process is important because it can help you fully understand how a diesel engine works. Naturally, if any part of this process stops working, it can have a deleterious effect on the performance of the diesel engine and some serious mechanical work will often need to be performed again to get it up and running again.
