Introduction When someone mentions diesel, many people still have the image of a loud and obnoxious machine that is hard to start in the cold weather. This may have been true twenty to thirty years ago, but could not be further from the truth today! With all of the advancements in engine and emissions technology; diesel has become the new standard in fuel economy and power while still maintaining strict pollution standards as mandated by the EPA. As C.J. Baker explained here, “Diesel development has come a long way, but the public perception of diesel is lagging 25 years behind...but the bottom line is still the same. Modern diesels are quick, powerful, quiet, easy to start in the cold, and don't smoke.”(Baker 2). Therefore I have chosen modern diesel as my topic, to help shine some light on the misunderstood beast that we call diesel. Also I hope to inform the public, that there is alternative technologies to gasoline and hybrid gasoline-electric vehicles, that perform a multitude of times better, while not damaging the environment. Diesel Fundamentals The way a diesel engine operates is drastically different from gasoline, instead of a spark plug pulsing seventeen times a second to initiate the explosion of the fuel, diesel relies on compression to generate the heat required to ignite, and create the explosion of the fuel. Also because of this diesel engines need to be built much stronger to endure the high-compression ratios required to contain the explosion. According to Lucy Lazarony, diesel cars and trucks provide twenty to thirty percent better fuel economy than comparable gasoline models (para. 1). This is because down to a molecular state diesel has “eleven percent more energy per gallon”(Baker, para. 7).

Why diesel engines are important to me and society? Diesel engines contribute to nearly every city, town, village, ect. in the USA, for the simple reason that people in the cities have no other way to get food or water, so they need semis to deliver food to grocery stores. Diesel engines are also needed for transportation or for construction, as well as just a daily driver.
On the whole, the purpose of the petrol and diesel engine are the same, to combust fuel
A majority of the population probably uses diesel fuel in automobiles, and central heating systems to heat buildings and houses. However, diesel fuel is dangerous to the environment. There is another option that can be used in place of diesel oil to fuel cars and to heat buildings. “Biodiesel is a legally registered fuel, and fuel additive with the U.S. Environmental Protection Agency (EPA)”, and it is made from “vegetable oils, yellow grease, used cooking oils, and tallow” (“Biodiesel Production and Distribution”). Biodiesel fuel has many advantages over diesel fuel that allows it to be a better fuel than diesel fuel such as improving the environment, decrease the U.S. dependency on foreign petroleum, and reducing the amount of hurtful contaminants.
Currently in the United States, diesel engines are an option over the standard gasoline engines, adding a few thousand dollars to the cost of a new vehicle. Although buying a diesel engine is a higher monetary investment initially, automakers say diesel engines make up this cost difference within just three years from fuel savings alone. Diesel engines also add greater resale value to pickups and SUVs due to their
After Diesel’s death, the diesel engine underwent much development and became a very important replacement for the steam piston engine in many applications. Because the diesel engine required heavier, more robust construction than a gasoline engine, it was not widely used in aviation. The diesel engine became widespread in many other applications, however, such as a stationary engines, submarines, ships, and much later, locomotives, trucks, and in modern automobiles. Diesel engines are most often found in applications where a high torque requirements and low RPM requirements exist.
Diesel engines are the biggest part to America and the world than people give them credit for. They help ship your groceries, building supplies for that new daycare down the street, new car parts for your favorite auto shop. They are one of the biggest aspects of this nation and nobody seems to respect them. That’s why in my future I aspire to work on diesel trucks, I've always had the biggest interest in cars and how they worked, that’s why I've chosen this career. Everyone thinks that it's a horrible line of work busting your knuckles all day, but if you have the right people with you that are fun but get the work done it seem like minutes.
Diesel has a lot of benefits compared to petrol. One of these benefits are that these diesels engines produce greater torque making the engine more efficient and powerful. In an article written by Chuck Schifsky “Gas vs. Diesel for Truck Trend “Diesel fuel has a higher energy density than gasoline. One gallon of diesel contains approximately 147,000 BTUs of energy,
85% equipments use single-cylinder diesel engines, while the rest use multi-cylinder ones. In the market of multi-cylinder diesel the competition is less intense because of excessive demand. The prospect is much more promising. Longxi has a certain competitive advantage in this market, resulting from its popular product such as SL2100.
...d not be able to make the long hauls across the country that they do, they would not be as dependable, or as efficient. There are other areas where diesel power would be missed, such as cranes, generators, bulldozers, road graters, and tractors/combines. All of these vehicles would be useless without the mechanics that fix and maintain them.
Flynn et al. [4] studied a turbocharged, intercooled diesel engine using second law analysis to evaluate low-heat-rejection engine concepts. They were performed the simulation of engine cycle process. Primus and Flynn [5] reported a study demonstrating the benefits of using the second law in determining various energy losses in a diesel engine. Defining a thermodynamic system as outside the engine cylinder. Alkidas [6] applied energy and exergy balances to a diesel engine using experimental measurements. Shapiro and Van Gerpen [7] extended their earlier work to include a two-zone combustion model and applied this model to both a compression-ignition and a spark ignition engine. As before, their study included chemical exergy considerations. They presented the
My answer to case study question is “Yes, they are”. There are proofs showing that petrol (gasoline) cars are more powerful compared to diesel cars. The main difference between diesel cars and petrol cars is the ignition. Petrol engines use spark ignition whereas diesel engines utilize compression ignition. This gives petrol cars a faster, more powerful start and higher BHP(brake horse power), which means higher KW. Chris Rosamond, an author from Auto Express, a weekly motoring magazine in the United Kingdom stated that diesel engine power band was usually relatively narrow when compared to a petrol engine(Chris, 2017). However, Chris was not the first one who said that. Daniel L. Hittler, A.M.C’s director of power-plant engineering
Diesel engines are a marvel of the world and have been since creation in 1892. Today there are several types of these engines including, two-stroke and four-stroke engines as well as the idea of how diesel engines operate. The diesel engine is a necessary component of the shipping industry as well as the daily lives of people.
Have you ever wondered how you would get around without your car? Rudolf Diesel created the perfect thing, a Diesel engine. Now with the invention of an engine, we can get wherever we need to go. Rudolf diesel’s life and invention has impacted the world greatly.
Most people today fill up their car with different qualities of petrol, because that's what the average car takes. They don't usually consider an alternative for the petrol that they load into their cars. Although petrol is widely used, it is not the only source for a car to get its power from; diesel and electricity are alternatives to the general petrol used by most cars. Although different from each other, diesel and electricity are alternatives to the average gasoline received at a gas station. Diesel is a more concentrated type of fuel that is usually used by big automobiles because they require a lot of power in a little amount of time. Electricity is a method that uses the power of batteries to produce a low horsepower but, nevertheless fast automobile. Electric cars are generally created to be soundless and environment friendly. The purpose of this paper is to classify and educate the reader of the different types of fuel available for an automobile to use: petrol, diesel, and electricity. The general petrol, used by most people, is usually the only type of fuel accepted on the average car in the United States today.
