What Makes Diesel More Efficient?

Engines come in all shapes and sizes from steam to internal combustion and one cylinder to v-12. The diesel engine however, is one of the oldest in the industry. Rudolf Diesel took out the first patent in 1892 but started working on it about 10 years earlier. He took some oil and refined it to make diesel fuel. He then put it in a sealed container and compressed it to make it ignite. The diesel engine is used in almost all applications known today. From construction, have equipment, lawn mowers, everyday cars and trucks, to semis, boats and trains. The diesel engine is an excellent motor that provides enormous power, excellent fuel economy, and if taken care of reliable for life. First off, I’m going to explain how the diesel engine …show more content…

Because of how the fuel burns, diesels are up to 40% more efficient that gasoline engines. Diesel also has about 11% more energy by volume increasing the fuel efficiency. Compression ratios also tend to play a factor. The average compression ratio for gasoline engines is between eight and twelve to one, while the compression ratio on a diesel can vary from twelve to sixteen to one or more. For example, my 1996 Chevy truck has a ratio of 9.5 to 1, while my father’s 2011 Dodge Ram Cummins has a compression ratio of 17.3 to 1 get an average of 5 to 10 better fuel mileage. Due to the higher compression ratio. The engine is able to extract more power out of less fuel. There are also tuning that people can do to the engine to increase the fuel mileage of diesel engines. Another way that diesel engines are more superior to gasoline engines is the durability of the engines. Diesels are put under much more stress and usually do more difficult of work. Because of this they are deemed to be overbuilt. With higher cylinder pressures and more boost levels they are built with heavy duty parts. With stronger engine blocks, forged steel crankshafts, connecting rods and even pistons they are less likely to break under heavy load. Most diesel engines can last on the road to around 500,000 miles to even lasting well of 1,000,000

Diesel service technicians held about 270,000 jobs in 2009. They were employed by almost every industry; in particular, those that use trucks, buses, and heavy equipment to deliver, haul, and transport goods, materials, or people. The diesel truck transportation industry is the largest employer for diesel technicians and mechanics. They employ nearly one out of every six diesel service technicians and mechanics. Slightly fewer were employed by local governments, mainly to repair their fleets of trucks, buses, and road equipment.

In contrast to gasoline powered vehicles, fuel cell vehicles completely run off of electricity and its by-products become water and heat thus meaning fuel cell vehicles don't emit emissions that could cause pollution unlike gasoline powered vehicles (Union of Concerned Scientists, 2018). The energy in 1 kilogram of hydrogen gas is about the same as the energy in 2.8 kilograms of gasoline. Hydrogen fuel cell vehicles can run more miles than gas or solar-powered vehicles. Fuel cells are a more efficient alternative and they are able to reduce the use of of other fuels and prevent oil depletion since hydrogen is an abundant element in nature .It

Diesel has increased about four tenths of a gallon since a year ago, a year ago it was $2.428 and now it is $2.837. When you have a diesel truck your truck will in other words “suck” some diesel which means that when you fill up a truck by the end of the week you will have to refill your tank again. Say for example, like me when I drove my mom’s dually for one week and by the end of the week I had to get more diesel, and to fill her truck up it takes about seventy dollars’ worth. The highest ever gasoline and diesel prices ever recorded in history is $4.114 and these gas prices was recorded in July 17, 2008 and the highest diesel price was also recorded this year and it was $4.845. Compared to today the prices have decreased by at least two dollars and hopefully it will not increase in the next year,

If that’s not enough, a diesel vehicle also has what is known as a Diesel Particulate Filter. A Diesel Particulate Filter Collects all the soot and much of the harmful contaminants released from the tailpipe before the DEF fluid is used and stores them. In other words a Diesel Particulate Filter or DPF collects and stores what makes diesel exhaust look black in color. With how a DPF works it must have regular scheduled ‘regeneration’ cycles where the diesel vehicle idles at around twice than normal rpms and cannot be turned off until all the collected soot, particles and contaminants are forced back through the engine then burned off into the atmosphere. What this translates to is that all the black soot is heated until it is no longer black, then put right into the atmosphere.

There has always been those certain environmental people that say that diesel trucks are bad for the environment. What those people do not usually know is not surprising to anyone that knows a diesel engine.

Biological or chemical attacks are deliberate releases of germs or any other biological substances that can make a person sick or kill them. Deliberate attacks are not just a United States problem, attacks can happen anywhere on Earth at any time. The CDC’s Office of Public Health Preparedness and Response (OPHPR) deals with the nation’s health security with any threats that may harm the United States and worldwide. Inside the OPHPR there is a department called the Emergency Operations Center (EOC) they work along with other government agencies like Homeland Security to protect the United States from deliberate attacks. The EOC uses a system very similar to the PSHA emergency incident command system that has a common response system, emergency

The steam locomotive invention started with the steam engine. " This involves water and fire, which is used to create heat. Coal, or wood is frequently the fuel that is used to create the fire, although oil was also used. The fire is used to heat the water which in turn creates the steam that causes the wheels to turn"(Transportation History).

Gasoline and diesel are fossil fuels and aren 't infinite. Battery electricity are better, they don’t pollute and don 't burn fossil fuels. Instead of having a gas tank and having to fill it up at a gas station, these cars have batteries in their place and can be recharged with a larger charging station and needs 220 volts. The recharged batteries stay charged until the car is driven. Some people say that battery powered cars are slower, but it isn’t by much and battery powered cars think is worth slowing down a little if it means saving the planet.
