Diesel engines have been around for centuries, and their evolution has been remarkable. From the earliest diesel engines used in locomotives to today’s high-performance diesel used in cars and trucks, they have come a long way. But with technological advances come questions about whether diesel engines are still viable. And if you want to reduce co2 emissions as a bonus, then AIC technology is the perfect choice for you.
We will examine the pros and cons of diesel engines, such as their durability and fuel economy, as well as their downsides, such as their higher emissions and cost. By the end of this blog, you will better understand diesel engines and their impact on the environment and the automotive industry.
Let’s start.
Definition of Diesel Engine
A diesel engine is an internal combustion engine that uses the heat generated from the compression of air and fuel to create energy. Diesel engines are different from gasoline engines because they use diesel fuel instead of gasoline. Diesel engines are often used in trucks, trains, ships, and other large machinery because they have high torque and require less maintenance. They are also widely used in electrical generators called ” Diesel Generators.”
History of Diesel Engines
The diesel engine is named after its inventor, a German engineer, Rudolf diesel. Diesel was born and grew up in France; after some time, he went to England during the franco-german war. Once the conflict was over, he returned home and studied design concepts. During the 1880s, he made numerous advancements in the steam engine concept, but the high price of coal made it difficult to operate. So, later he wanted to invent something that could help small businesses to compete.
Finally, he discovered that he could make a small, internally combusted engine that could convert heat into mechanical energy. By 1904, France started using his engines in their submarines because the fuel was heavier and at a lower risk of flammability.
Pros of Diesel Engines
Following are the advantages of a diesel engine. Let’s have a look at them one by one.
1. Durability
When it comes to durability, there is no match for diesel engines. They can withstand extreme temperatures and are reliable because of their fewer moving parts. While most gasoline engines have about 40 moving parts, diesel engines have just 12 to 15 moving parts, which means there is less that can go wrong. Consequently, it would require less maintenance. Due to their durability, diesel engines have a long lifespan, lasting more than 500,000 miles.
2. Fuel Economy
Diesel engines produce more power per unit of fuel than other engines, which means they can achieve better fuel economy. Diesel engines can consume up to 50% less fuel than gasoline engines. This is because diesel engines produce more power per unit of fuel. While gasoline engines produce around 100 horsepower per gallon of fuel, diesel engines produce around 200 to 300 horsepower per gallon.
3.Torque
Diesel engines have higher torque than other engines, which means they can handle heavy loads with less stress. Diesel engines produce more torque because they are designed to produce more power by burning more fuel. This is one of the reasons why diesel engines are more efficient than gasoline engines.
4. Better Resale Value
By assuming that you kept up with the standard maintenance schedule with your diesel engine vehicle, you’ll find a comparatively better resale value. Even if the body of the car isn’t in tip-top shape, the quality and longevity of the engine will make your diesel continue to be a tempting offer. Their durability, performance, and overall handling make them a useful option long after their counterparts wear out.
5. Multiple Fuels
If you buy a gasoline-based engine, gasoline is your only fuel choice. You can use ethanol blends to a specific limit, which will surely decrease your car’s gas mileage.On the contrary, if you choose a diesel engine, you can burn multiple fuels. For example, if you have a frugal mindset, waste vegetable oil is a better option. Many restaurants will give you that (in the form of grease) for free. Besides, you also do have the option to create biodiesel at home. But you can’t refine the gasoline, so that means diesel engines give you more flexibility in this way.
Cons of Diesel Engines
Beside having certain advantages of Diesel engines; there are some disadvantages of diesel engines as well. Let’s have a look.
1. Cost
Diesel engines cost more to maintain and to fuel than gasoline engines because diesel engines require special fuel and filters that can’t be used with gasoline engines. This means you have to buy diesel fuel and diesel-compatible parts and filters. They also have a higher chance of breaking down and need more maintenance than gasoline engines. Diesel engines also have higher upfront costs and are more expensive to repair.
2. Environment
While diesel engines produce CO2 emissions per gallon of fuel, they produce much more CO2 overall in comparison to other engines. This is because the people who own diesel vehicles, like buses and trucks, drive more miles than those who drive alternative fuel vehicles. This means they consume more fuel and emit more CO2. Diesel engines are also known to cause air pollution, making them less environmentally friendly than gasoline engines.
3. Cold Performance
Impaired performance in cold weather is another drawback of diesel engines. In cold temperatures, Diesel fuel can convert into the gel. More specifically, below 40 degrees Fahrenheit, Certain hydrocarbons in diesel become gelatinous. So, for this purpose, manufacturers or drivers must install engine block heaters and glow plugs or keep the engine running in cold weather.
4. It's Messy
Diesel has a much greater viscosity than gas, which is much cruder and messier. It can be easily spilt and slower to evaporate after it spills, making it very easy for dirt and dust to settle on it. Diesel is quite putrid in its usable form. It also emits dirty black smoke while running the engine, which is very unpleasant and can cause air pollution.
5. Noise
Diesel engines are noisier than gasoline engines, which can be trouble for people who live near highways. The reason why they are noisier is because they require more heat to start. This high-temperature combustion ultimately creates more noise.
Diesel Engines are Far better than Gasoline Engines
Diesel engines are not new, but they have been in the limelight recently due to their high efficiency compared to gasoline engines. Diesel engines operate at a higher temperature than gasoline engines and convert more of the fuel they burn into energy. This means they produce more power per gallon of fuel than gasoline engines. Diesel engines are also more durable than gasoline engines due to their fewer moving parts. This means they can achieve better fuel economy, last longer, and emit less CO2 than gasoline engines. Although diesel engines are more expensive to maintain, they are still a viable option. And as technology advances and more advancements are made, diesel engines will become even more efficient and environmentally friendly.
Conclusion
The diesel engine is among one of the biggest inventions of its time ever made by German engineer Rudolf diesel. We explained the pros and cons of diesel engines in a detailed manner. The diesel engine is far better than gasoline and other engines regarding durability, torque and fuel economy. Plus, point of diesel engines is that they do have a better resale value even if they aren’t in very tip-top condition. But diesel engines are also lacking at some points, like pricing, producing noise and co2 emissions. So, you do have a lot of information about diesel engines; including benefits of diesel engines along with comparison of diesel engines with gasoline ones. Just decide carefully.
