Diesel engines automatically put two images in your head when you think about what they represent; hardness and dollars. They are built to last and perform, but all drivers realize that diesel fuel costs money to operate and maintain. There are many pros and cons to buying a diesel vehicle, and thinking about what could go wrong is an important part of making an informed decision about which engine will work best for you. The development of diesel as a fuel source dates back many years and has lasted throughout history to provide efficiency and endurance and has become a popular choice for fuel power. In 1878, a man named Rudolf Diesel was studying in Germany at the Polytechnic College, something similar to what we know as an engineering school. During your studies, you learned about the low efficiency of gasoline (remember it was many years ago) and steam engines. The information was so shocking to him that he decided he needed to spend his time developing a more efficient engine and tried to create a “combustion engine”, or what we now know as the diesel engine for which he received a patent. in 1892.
Why do most cars have gasoline engines? Clearly, diesel engines are not found in cars as often as gasoline engines. According to auto experts, the 1970s gave a small boost to the popularity of diesel engines in sales due to the OPEC oil embargo. At that time, it was first used in cars during the oil crisis and people found their cars covered in soot. Although there are many advantages of diesel engines that will be explained later, many people find too many disadvantages. First, they tend to be much heavier due to their higher compression ratios. They also tend to be more expensive than gasoline engines. This alone is important to most people when choosing their perfect vehicle. Third, due to their weight and compression ratio mentioned above, diesel engines tend to have lower maximum RPM ranges than gasoline engines. This makes diesel engines high torque rather than big power, and that generally seems to make diesel cars slower when it comes to acceleration speeds. Additionally, diesel engines must be injected with fuel, tend to produce smoke, and are described by many observers as “odd-smelling.” They can be more difficult to start in the cold winter, and if they contain what are known as glow plugs, diesel engines may require you to wait a moment before starting the engine for the glow plugs to warm up. Many people also notice that they are louder, tend to vibrate more than gasoline engines, and in some areas diesel is less available than gasoline. This is a problem for people who drive diesel cars or trucks for work or in their everyday vehicles.
On the contrary, auto experts admit that diesel vehicles are quite efficient and have come a long way in recent years. Many people wonder why there aren’t more vehicles with diesel engines if they have the important and modern description of “efficient.” There is still a negative image of diesel trucks that makes diesel engines seem less attractive to those who drive full-size cars. Diesel is perfect for hauling large shipments and heavy loads over long distances and on rough terrain, but due to size, weight, noise, and vibration, it is typically not the right choice for everyday commuters in smaller vehicles that may not be able to do it. to drive the engine itself. Engineers and automotive experts are beginning to make diesel engines cleaner burning and less noisy to make it a little more attractive to the everyday driver.
Emissions from burning diesel is an area that has vastly improved over the years. Compared to emissions from unregulated engines of 40 years ago, today’s on-highway diesel engines emit 99 percent less PM and NOx. According to one engine manufacturer, in 2010, all heavy-duty diesel engines sold in the United States had to meet the “NOx standard (0.20 grams per hour of brake power (g / bhp-hr)) and the PM standard (0.01 g / bhp-hr) “as established by the Environmental Protection Agency. These are the strictest emissions regulations in the world according to experts and as manufacturers continue to create better and more universal diesel engines, it is good to know that they will have to continue to follow these same strict regulations. If diesel fuel were not efficient, it would not have stood up to being the main fuel used to transfer goods across the country. As mentioned above, diesel fuel is heavier and oilier than gasoline. While diesel engines tend to emit nitrogen compounds and particulate matter when burning diesel fuel, they actually emit lower amounts of carbon monoxide, hydrocarbons, and carbon dioxide than gasoline. There are also new direct injection devices that are controlled by a type of computer that monitors fuel combustion in the engine. This leads to better energy efficiency and lower emissions. There are also other new devices on the market that make diesel engines even better; Catalytic converters and CRT particulate filters are reducing soot, carbon monoxide and hydrocarbon emissions by nearly 90%, as stated by the Diesel Technology Forum.
Unfortunately, when it comes to diesel cars and trucks, there are a lot of things that could go wrong. Because diesel engines are larger and a bit more intricate, they can cost more to repair at an auto repair shop. They still require regular maintenance to keep them running at optimum performance. You must change the oil, air, oil, and fuel filters. Although cleaner diesel fuels mean that you no longer need to bleed excess water from the system, many vehicles still have water separators that must be emptied manually. Also, when you neglect regular maintenance on a diesel engine, the fuel system could break down. If this happens, a repair can cost more money for parts and labor than a traditional gasoline engine. Diesel engines are quite technologically advanced and because technology changes frequently, diesel mechanics must stay trained in advancements in order to properly repair diesel engines. Not all mechanics continue this training, and not all auto repair shops can repair or maintain diesel trucks. Part of the decision as to whether or not you would consider a diesel engine should be whether or not you have a trusted mechanic who is capable of performing the tasks on the engine. Once again, the government has recently lobbied engine manufacturers to create attractive low-emission diesel engines for passenger cars. They could not only be used with passenger vehicles, but also with trucks, buses, vans, and agricultural and construction equipment. This pressure continuously produces newer and more advanced low sulfur diesel fuels and catalytic converters, advanced filters and other devices that have the ability to reduce toxic emissions.
According to diesel experts, diesel engine failure is usually the result of faulty diesel fuel or a lack of routine maintenance. The problems begin with the diesel engine itself, destined for diesel failure. Diesel fuel is unstable and solids will begin to form creating a sludge-like substance in the tank. It can eventually clog the diesel fuel filters, ruin the injectors, and even cause the engine to smoke. According to one company, “Pollutant build-up is the result of excessive microbial growth and biodegradation of diesel fuel can lead to fuel filter clogging. Microorganisms, bacteria and enzymes, fungi, yeasts and molds cause diesel fuel degradation and lead to major diesel engine failures. ” It is important to know what you get with a diesel engine. In the future, it may be an advanced engine for passenger cars and larger work or transfer vehicles. For now, it may be a bit premature to rush out and find a diesel-powered vehicle.
