Diesel vs Gas Engines, What's the Difference?

If you're going to make a smart decision when buying a vehicle, it's essential that you know the difference between gas and diesel engines.

It's well understood that diesel engines provide a lot of benefit gas ones don't, but what are those reasons and why does everyone use gas? We'll cover all of that and more in this article.

This is information you need to know if you want to put more money in your pocket and do a little justice for the environment. Here's the difference between diesel vs gas engines.

Diesel vs Gas Engines

The United States and Canada tend to have a stigma towards diesel engines. Strangely, Europe, Central America, South America, Africa, and Asia don't share those feelings. Let's unpack a few of the differences between gas and diesel before we get into why gas is so popular here.

Diesel Engines

Diesel and gas engines both aim to serve the same purpose. They are combustion engines that change chemical energy in fuel into mechanical energy to push the engine. The mechanical energy enters different elements of the engine to allow it to propel the vehicle and get you where you need to go.

Diesel engines inject fuel into compressed air, which then heats up and ignites. These engines use for strokes: The intake stroke, compression stroke, combustion stroke, and exhaust stroke.

Diesel fuel, like gasoline, starts out as petroleum, a crude oil that gets produced within the earth. When refined into diesel, the petroleum is turned into an oily, heavy substance. Its oily nature is a result of the fact that it is closer to the original petroleum than gasoline is.

For that reason, it takes less effort to refine, which is why it used to be significantly cheaper than it is now. The price has risen, unfortunately, for economic reasons that have thrown the supply and demand out of balance.

It also has a higher ability to produce energy per unit than gasoline, making it fortunate that most of our large, high usage trucks and transportation vehicles use gasoline.

Gasoline Engines

The primary difference between diesel and gas engines is the point of fuel ignition. Fuel and air are compressed in gasoline engines which then ignites the compressed substance with a spark plug. The diesel engine ignites from the fact that the compression heats the fuel to the point of ignition.

The presence of a spark plug puts vehicle owners in the position of needing to replace and maintain more often. Diesel engines are typically built to last a good deal longer than gasoline ones. Additionally, diesel engines are known to get gas mileage regularly above the 30 miles a gallon mark.

A final factor that you should consider is the fact that diesel emissions are much better for the environment than gasoline emissions. The reason that many people frown upon diesel is the fact that you can see the emissions.

The idea that just because you can see the emissions, they are more harmful is something borne of ignorance.

Get Your Diesel Fix

There is a lot to understand when it comes to diesel vs gas engines. After you've made the decision to purchase your diesel vehicle, you need to make sure that you keep it in tip-top shape. In any vehicle that utilizes diesel, it's likely that you aren't used to the specifications of the engines.
