Remarkable Achievements of Diesel Engines

When it comes to engine configurations, only a few of them granted improvement to the economy of fuel as well as power. This is also applicable to engines. Fortunately, countless individuals today are getting the huge benefits of the diesel technological advancements.

In America alone, a lot of historical events were being highlighted regarding diesel. For instance, General Motors made the 350ci gas V8 to be operated using diesel in 1980. Unfortunately, the results were unimpressive since it gave a slow performance and was not really that dependable.

But Mercedes Benz got a lot of luck regarding diesel engines. During the 1980s, they produced various vehicles using diesel engines. Even though these vehicles were kind of noisy and produced some smoke, it’s good to know that they can survive for an extended period of time. Even Volkswagen used diesel although it was common for blue smoke to come out of the tail pipe.

Fortunately, the vehicles of Benz and Volkswagen using diesel improved a little bit. They became smoother, cleaner and even more powerful than before. However, the kind of horsepower needed by many people was still not met by these two vehicle manufacturers.

It’s amazing to know that today, Benz and Volkswagen are not the only manufacturers offering diesels. In fact, Jaguar, BMW, Ford and other companies offer diesel as well.

Technology made a lot of improvements to various engines nowadays. In the case of diesel, Europe got so many benefits regarding their vehicles’ acceleration. One example is BMW’s 120d. With its 163bhp, it can go up to 60 in less than 8 seconds. Moreover, about 49.6 miles can be reached every gallon.

Benz also made improvements as evidenced by its C320 CDI SE which has 224 bhp and a 360 lb foot torque. This model can go between 0 and 60 in less than 7 seconds. There’s no vehicle in North America that can have this kind of superior performance.

The reason why diesels haven’t caught on in North America comes down to one word – sulfur. We have too much sulfur in the diesel here in the United States. This cheap grade of diesel fuel will run havoc on the more sophisticated diesels offered overseas and cause an increase in emissions.

There is hope however, as refiners will soon be producing what is known as ultra low sulfur diesel fuel. This will help to reduce the sulfur content from 500ppm to 15ppm.

In-depth Review About Diesel Fuel

It’s amazing how diesel engines rapidly evolved today. Almost everything about it has advanced. The fuel delivery, the combustion chamber, its power, sound and many more have been enhanced. But when it comes to diesel fuel, it’s unfortunate that its advancement is lesser compared to the evolution of diesel engines.

Oxidation is a natural process taking place among all kinds of diesel fuels regardless of the brand. Take note that deterioration starts to occur right away upon the production of diesel fuel. When oxidation starts, diesel fuel will start to form those gums and varnishes due to the bonding and lengthening of the molecules.

The components within the diesel fuel will then proceed to the lower part of the fuel tank where it will create diesel sludge. When this happens, the color will darken and its smell will go foul. Moreover, the engine will also produce smoke as a result of those very small clusters passing through the filtration and the combustion chamber.

As the clusters begin to increase in size, only a small amount of the molecules will get burned, as the rest will go out the exhaust as unburned fuel and smoke.

There may be different causes of diesel engine failures but most of them are due to either poor quality or fuel contamination. A contaminated fuel can trigger clogged filters. As a result, the engine would shut down and would also be damaged.

But the most common cause of a bad fuel is due to its increase in demand. Typically, diesel fuel should be stored in refinery storage tanks at a specific duration. Storing diesel fuel can allow them to separate in a natural way wherein the clean part can be acquired. But since more and more people are buying diesel fuel, the fuel can’t be still for a sufficient amount of time. Therefore, even the dirty particles will be used by the buyer.

Another problem being noticed was how the diesel fuels these days are refined. The change in the refinement process triggered low quality diesel fuels. In fact, the level of contamination is even higher than before.

Until today, the society can’t do anything but hope that diesel fuel quality will improve in the near future. Undeniably, the present quality is not really beneficial. If you’re one of those individuals buying diesel fuel, the least that you could do is hope that your fuel is not contaminated.

A Brief Review About Diesel Industrial Engines

As its name implies, industrial diesel engines are those engines used for industrial purposes or those seen on industrial machinery. You can see them on generators, bulldozers, trucks or motorbikes. Their sizes vary as well. Some can be light while others are extremely heavy with different power levels.

The use of diesel engines is mandated by several large organizations. All NATO machinery for example, runs on either diesel or aviation grade kerosene. At the current level of technology, fossil fuels, and especially diesel are the most economical and convenient means of supplying power to a variety of equipment and even backup generators.

Industrial diesel engines can be water or air cooled. Approximately 10 kW is provided when it comes to those small engines which are used for residential purposes. These small engines are useful among farm equipment, trucks, earth movers or a machine which tend to be stationery.

Medium scale industrial diesel engines can give more than a hundred kW while others can reach a few thousand. They are useful in powering up bigger machinery. This includes oil rigs, big boats, trains, equipment for military purposes, bigger mining equipment and many more.

Among all the industrial diesel engines, the largest can power up super heavy equipment, the biggest ships and those generators powered by electricity. These kinds of industrial diesel engines can give from 10,000 to 80,000 kW but can be sold for millions of dollars. One country using many of these engines is China since this country needs high demand for decentralized power sources.

The speed and RPM (rotations per minute) are the usual factors that categorize these industrial diesel engines. Normally, those with higher RPMs are utilized among lighter equipment such as trucks.

Engines with medium RPMs can be advantageous in terms of power generation. Meanwhile, low RPM engines with high torque are useful for the largest kinds of equipment.

These industrial diesel engines vary according to many factors like performance and size. In fact, you may have seen these kinds of engines already or used an equipment utilizing an industrial diesel engine. They may be quite expensive. However, they can give you the highest possibilities that you’ll finish your job right away with minimal or no errors at all.

Gas Versus Diesel

Cost – Due to the high compression ratios and resulting high cylinder pressure in diesel engines, they must be built to withstand a lot more punishment than gas engines. The parts that are spruced up include a thicker block and cylinder heads, pistons, crankshaft, and valves, which can be very costly indeed.

That’s why gas is the one victorious when the issue is addressed to the cost. Since diesel is more expensive, the number of people opting for gas is higher.

Fuel cost – Diesel fuel is easier to refine, taking less time to get from raw petroleum to final product from gas, giving it a lower price than that of gas. On the other hand, within the United States, diesel is priced the same or just a bit below regular unleaded gas.

Vibration and noise – Unfortunately, noise is still very noticeable among trucks using diesel fuel until today. Moreover, they also do a lot of shaking compared to those vehicles using gas. Even when a diesel vehicle is not moving, the vibration is still obvious. On the other hand, you can’t tell if the vehicle using gas is running.

Cold weather – This is another loss for diesel engines since it is easier to start gas engines during cold weathers. That’s because gas engines have those spark plugs which aren’t present on diesel engines. During cold temperatures, the air within diesel fuel is not yet that hot, hence, making it difficult for a diesel engine to start.

Maintenance – Unfortunately, the maintenance cost of diesel engines is higher compared to gas engines. Diesel engine maintenance includes a bigger amount of oil plus those fuel filters as well as the water separators require more frequent assessments. With gas engines, they have the excellent engine oil, the spark plugs and the antifreeze which make their maintenance easier.

When choosing between diesel and gas, it’s important to assess the place to where you live and the purpose of the vehicle. Gas vehicles are suitable for quick accelerations. But if your vehicle is utilized for carrying extremely weighty objects and you’ll be traveling greater than 100,000 miles, a vehicle using diesel engine is more recommendable.

A diesel engine is also a good choice if you’re after the fuel economy. Nevertheless, a gas engine is strongly suggested for a smoother running of your vehicle and if you’re usually in a place with a cold weather.

In terms of price, it’s always the diesel engines which are more expensive. But if you have a large budget and the price is not a problem to you, the best choice would have to be diesel. When buying one or more trucks, it’s also preferable to go for diesel especially when hauling colossal and heavy objects.
