The Diesel Engine Making a Comeback Essay Example

The Diesel Engine: Making a Comeback Essay Later in 1987, he made another model that operated at a whopping 75% efficiency (History). This was an incredible achievement because it meant that it could replace the work that steam engines do at a fraction of the cost. Nowadays diesel engine manufacturers are In competition with gasoline engine manufacturers. Diesels are making comeback to the Industry because they are quieter, lighter. More efficient, less polluting and more powerful than ever. Many companies recently have been releasing cars that have ridiculously high MEGS and more power than their gasoline counterparts. The people in the United States Eke the idea of a fuel efficient car, but get turned off when they hear he idea of a diesel car because of their reputation of being loud and stinky. People need to be reeducated because these Well 2 cons have been reversed and you can now own a diesel car that has the perks of a diesel engine while acing Like a gasoline engine (Brain). The Invention of the diesel engine has improved the lives of many people and has gone under many improvements in the last twenty years which has allowed the general public to have a more efficient and cost effective motive of vehicular transportation.

The early diesel engines were too large and heavy, because of the Injection pump, to be used for anything but stationary Jobs. This led to them being used in many industrial and shipping areas but also was used in ships and submarines. Ship builders took advantage of the engines efficiency because size did not matter on marine vessels. As the sasss rolled around, a new injection pump design came about that significantly reduced the size of the engine. It was not until 1936 that the diesel engine first appeared In an automobile. Mercedes sold to the arrest a full sized sedan called the Type 26TH. The manufacturer that made the that greatly improved upon the diesel. He owned a diesel engine company, along with an investment banker William Glutton Irwin, that was about to go bankrupt due to the stock market crash of 1929. To assure future investment in his company, he installed a diesel engine in a limousine and took his investor Irwin for a ride. About a year later, he had built a very efficient diesel truck that he drove from coast to coast of the U. S. On only $1 1. 2 worth of fuel. He did this to prove a point that diesel engines are economical and have a place in the automotive industry (History). Since this day, diesel cars have continued to become more and more popular among the public. Later in the sasss, the diesel engines ability to be very fuel efficient led to their popularity during the oil crisis of 1973 and 1978 (Brain ). Gas prices were very expensive for the time and diesel vehicles allowed the public to have more money in their wallets. Unfortunately, Well 3 these cars were not popular for that long, gas prices had went down and nobody wanted to drive them. They were very noisy and Just not as reliable as a diesel car should be. Since the market had a large demand, the manufacturers hurried them to the market and basically converted gasoline engines into diesels (Brain). This lead to them being of inferior quality and ruined the diesel market for the next 25 years until clean diesels came about. The operation of diesel and gas engines are very similar. Both are internal combustion engines that convert chemical energy, diesel fuel, into mechanical and heat energy. The fuel is ignited in both engines, but in different ways, and is inverted into mechanical energy by driving a piston up and down. The pistons are connected to a crankshaft, and the up and down mechanical energy, also known as linear motion, is converted into rotary motion via the crankshaft, which is then used to propel the wheels of a car (Brain). Both diesel engines and gasoline engines covert fuel into energy through a series of small explosions or combustions. The major difference between diesel and gasoline is the way these explosions happen. In a gasoline engine, fuel is mixed with air, compressed by pistons and ignited by sparks from spark plugs. In a diesel engine, however, the air is compressed first, and then the fuel is injected. Because air heats up when its compressed, the fuel ignites. (Brain) Diesels do not use spark plugs to aid in combustion, the heat of the compressed air is what solely explodes the diesel fuel. Another major difference between the two engines is the injection process. Gas engines use indirect fuel injection that allow the fuel to mix with gas before even entering the cylinder. Diesels use direct injection, the diesel fuel is mixed injected directly into the cylinder right before the piston reaches the pop. One of the the most technologically advanced parts of the diesel engine is the injectors. The injectors have to withstand the pressure and heat of the cylinder (Brain). Recently, manufacturers have designed them to inject as little Well 4 fuel as possible while gaining more power and emitting less emissions (Templeton). What makes diesels so much more efficient than the gas engine is the fuel used and the higher compression in the diesel engine. Diesel fuel is a thicker fuel than gas and has the viscosity of thin oil. Gasoline is much thinner and contains less energy per piston stroke. Diesel engines also have about twice the compression of gas engines because the compression is what creates the heat to ignite the fuel. Because of this high compression ratio, diesels are built with stronger materials and a thicker engine block, This makes them suitable for heavy work and all applications in between. On average, a diesel can last about five hundred thousand miles versus a gasoline engine that can last at most two hundred and fifty thousand, but on average about one hundred fifty thousand miles (Brain). The diesel engine tends to rev at lower revolutions per minute than a gas engine, cause the diesel engine is heavier. But this is not a bad thing because they have much higher torque ratings than gas engines. Torque is the power that turns your wheels, horsepower what accelerates a car. This is another reason why diesels are often used to haul heavy loads. The problems with the older diesels are that they could not accelerate quickly (History). Manufacturers realized that adding a turbocharger increased horsepower, efficiency and fuel mileage while decreasing emissions. It Just happened to be one of the largest breakthroughs in the diesel industry. They also produce less smoke from the turbocharger. Most cars and trucks had turbots on them by the early asss. Diesel cars could now accelerate at the rate of most gas cars do, or even faster (Brain). One of the most recent advancements in diesel engine technology is the clean diesel. Diesels without any emissions equipment emit less carbon monoxide, hydrocarbons and carbon dioxide than gasoline engines. These are the gases that cause global warming. However, diesels do emit higher amounts of nitrogen compounds, which cause acid Well 5 rain. Although, with the new emissions on the clean diesels, they overall pollute less than most gasoline engines (Chiefs). Drivers that enjoy the mileage of the Pries or other hybrid cars would like the mileage and power of a diesel. The problem with most hybrids on the road is that they accelerate slow. Many owners have complained about the slow get-up of their hybrids. A diesel car, such as the Audit AY EDIT, could be the answer to these displeased owners. The Audit AY EDIT has Jaw-dropping 428 foot pounds of torque and 240 horsepower while getting 36 average miles per gallon. With these high power embers, the quietness of the engine, and a high average fuel mileage, the number of diesel cars sold in the United States in 2012 is about 3. % of all car sales. Even though the number sounds small, it is about the same percentage of the number of hybrids sold in 2012. The number of diesels on the road are supposed to double by 2018 (Davies). Heavy duty pick-up trucks are a majority of the sales. Their towing power is what makes them the most popular, along with the excellent fuel economy. The current 2013 F IEF with the 6. 7 L Overstrike has 400 horsepower and 800 foot- mounds of torque, while the gas version has only 385 horsepower and 405 foot- pounds of torque. The better of the two is obviously the diesel, with twenty-five more horsepower and four-hundred more foot-pounds of torque. Using the diesel version of the FIEF allows the owner to haul heavier loads quicker and with less fuel. The fuel economy does not decrease significantly when hauling with a diesel compared to a gas engine that drops drastically (Brain). The invention of the diesel engine has improved the lives of many people and has general public to have a more efficient and cost effective motive of vehicular remonstration.
