Diesel Vs. Gas Engines

Diesel Vs. Gas Engines

By:


Whether you're thinking about buying a diesel vehicle or becoming a diesel mechanic or merely want to compare a diesel powered vehicle to a more common unleaded gas powered vehicle, there are a few things you need to take into account and learn about. Each style of engine has its own positives and negatives, so knowing what you need and how you need it for your individualized lifestyle is extremely important.

Todays diesel engines aren't what they have been ten or even five years back. Gone are the times of stinky exhaust and unacceptably noisy engine noises. Diesel engines have become substantially cleaner, have more power and are a lot more dependable. These are some of the reasons that we are seeing increasingly more common automobiles with diesel engines rather than the traditional gasoline engine.

Lets look at several differences between these engine types.

Is One Type of Engine Better?

In theory, a diesel truck engine is rather similar to the engine of a truck powered by gas. Both are internal combustion engines designed to convert one type of energy to another type of energy. This energy then generates linear motion, which in turn causes forward motion to take place. The primary variation is how the combustion happens. A gas truck engine has fuel combustion come about because of sparks from spark plugs. A diesel truck engine has the fuel combustion happen through the heat of the compressed air inside the engine.

Safety of Each Engine

As any diesel mechanic will tell you, even though you can flame diesel fuel in the open air using merely a wick, it is far less explosive than gasoline and doesn't produce a flammable vapor. This means a diesel engine won't ever vapor lock. Furthermore, a diesel mechanic will explain that the engines in diesel trucks are usually more efficient due to their fuel efficiency, which is virtually constant in comparison to the sporadic nature of a gasoline engine which often can use more fuel to get less power.

Performance of the Engine

As most diesel mechanics will tell you, the thing that makes an automobile so attractive is its ability to accelerate rapidly. Because of this, we need to evaluate the performance difference between both engine types. Because engines in diesel trucks and cars are centered on torque as opposed to horsepower, they will run more efficiently but accelerate rather slowly in comparison. For most automobile owners, that lack of acceleration is unsatisfactory. For car owners who are seeking to use their car or truck for pulling large loads such as campers or boats, a diesel engine makes more sense.

Engine Efficiency
When you compare a diesel engine to a gasoline engine, we cannot forget the efficiency between both engines. If you are looking for an engine that's going to be used long-term, then a diesel engine will be good for you because you will save money over the lifespan of the engine. With 20 - 30% less fuel usage, the savings can really add up. Diesel engines also have a longer lifespan than their gasoline counterparts. A typical diesel engine can last around 350,000 miles before needing an overhaul, the gasoline counterpart is good for about 120,000 miles. If you're looking for short term benefits, however, then a gasoline engine will be for you since it will take a few years for a gasoline engine to be less economical overall than a diesel engine.

Ultimately the environmental benefit of using a diesel engine is what shifts the argument in favor of using it primarily. The engines of diesel trucks and automobiles generate only a minimal amount of carbon monoxide, so minimal, in fact, that they can be utilized underground. Less carbon monoxide influence on our atmosphere means a far healthier planet, that is certainly something we should all be striving toward.
