...example bio diesel was created because regular diesel fuel was making so much bad emissions that is harming the air quality and the environment. So they create it to help reduce greenhouse gas emissions for diesel vehicles. Diesel engines are more complex than a normal car engine. Instead of spark to start the engine like normal cars, a Diesel engine uses what’s called diesel compression. It’s what you need for the diesel engine to start. Instead of a spark plug it uses compression to heat up the cylinder to ignite the fuel, there is no need for a spark plug. But in the winter when it’s cold, they do have glow plug. All the glow plugs do is heat the cylinder up enough to get the fuel to ignite. Also Diesel engines run at a much higher compression than gas engines do. A diesel engine typically runs 16:1-23:1 or 250-350 psi. (Robert Baker February 2010) Biodiesel is made from used cooking oil mostly. It can be made from any type of vegetable oil, used or not, but not from petroleum based oils, like motor oil. It has to go through a cleaning process through adding ingredients such as catalyst and methanol. You cannot take straight used vegetable oil and run it through your motor; it will clog the engine and create huge problems. Using biodiesel has been known to make engines run smoother and cleaner. It has higher lubricity content then diesel does and also has a higher cetane value which will increase power not by much but enough to be noticeable on a diesel engine. (Robert...

...In 1878, Rudolph Diesel was attending the Polytechnic High School of Germany when he learned about the low efficiency of gasoline and steam engines. This information inspired him to create an engine with a higher efficiency, and he spent much of his time developing a “Combustion Power Engine.” By 1892 Diesel had obtained a patent for what we now call the diesel engine. The invention of the diesel engine made our economy run in a more efficient way than anyone ever thought possible. (Brain, “How Diesel Engines Work”) When Diesel obtained the patent for the diesel engine in 1892, it opened up the economies of many countries for greater success. It was invented because the gasoline and steam engines of the day were not efficient according to standard. Diesel also made efforts to reduce pollutants and emissions but was unsuccessful. (Rudolph’s Revenge) A huge question arises when talking about diesel engines. What is the difference between gasoline and diesel engines and how do they work? In some ways, diesel and gasoline engines are quite similar. They are both internal combustion engines designed to convert the chemical energy available in fuel to mechanical energy. This mechanical energy moves pistons up and down inside cylinders. The pistons are connected to the crankshaft, and the up and down motion of the pistons creates the motion needed to turn the wheels of a car forward. However, the major difference between diesel and gasoline is the way these combustions happen. In...

Rudolf Diesel and his invention diesel engine is the object of the paper. The goal of the paper is to analize this invention, talk about Rudolf Diesel and his theory of diesel engine, its advantages and disadvantages, types and working principles. The diesel engines of today are refined and improved versions of Rudolf Diesel's original concept. They are often used in submarines, ships, locomotives, and large trucks and in electric generating plants. Technology has affected society and its surroundings in a number of ways. In many societies, technology has helped develop more advancedeconomies (including today's global economy) and has allowed the rise of a leisure class. Many technological processes produce unwanted by-products, known as pollution, and deplete natural resources, to the detriment of the Earth and its environment. Contents INTRODUCTION 4 1.

...Inventor: Rudolph Diesel Invention: Diesel Engine Year: 1892 The diesel engine is the most efficient prime mover commonly available today. Diesel engines move a large portion of the world's goods, power much of the world's equipment, and generate electricity more economically than any other device in their size range. However, the diesel is one of the largest contributors to environmental pollution problems worldwide, and will remain so, with large increases expected in vehicle population and vehicle miles traveled (VMT) increasing global emissions. Diesel emissions contribute to the development of cancer; cardiovascular and respiratory health effects; pollution of air, water, and soil; soiling; reductions in visibility; and global climate change. The main changes required to use diesel fuel are driving a different car, locating diesel-fueling stations, and knowing the differences in fuel economy, greenhouse gas emissions, and other aspects that arise from using diesel as a fuel instead of gasoline. While diesel has merit to help an individual save money and prolong the life of his or her vehicle, it also has negative side effects. The regulation requires diesel trucks and buses that operate in California to be upgraded to reduce emissions. Heavier trucks must be retrofitted with PM filters beginning January 1, 2012, and older trucks must be replaced starting January 1, 2015. By January 1, 2023, nearly all trucks and buses will need to have 2010 model year engines or equivalent...

...The diesel engine (also known as a compression-ignition or CI engine) is an internal combustion engine in which ignition of the fuel that has been injected into the combustion chamber is initiated by the high temperature which a gas achieves when greatly compressed (adiabatic compression). This contrasts with spark-ignition engines such as a petrol engine (gasoline engine) or gas engine (using a gaseous fuel as opposed to petrol), which use a spark plug to ignite an air-fuel mixture. A Diesel engine built by MAN AG in 1906 The diesel engine has the highest thermal efficiency (engine efficiency) of any practical internal or external combustion engine due to its very high expansion ratio and inherent lean burn which enables heat dissipation by the excess air. A small efficiency loss is also avoided compared to two-stroke non-direct-injection gasoline engines since unburnt fuel is not present at valve overlap and therefore no fuel goes directly from the intake/injection to the exhaust. Low-speed diesel engines (as used in ships and other applications where overall engine weight is relatively unimportant) can have a thermal efficiency that exceeds 50%.[1][2] Diesel engines are manufactured in two-stroke and four-stroke versions. They were originally used as a more efficient replacement for stationary steam engines. Since the 1910s they have been used in submarines and ships. Use in locomotives, trucks, heavy equipment and electricity generation plants followed later. In the 1930s...

...was that diesel was the only way to deliver significant fuel economy improvements in trucks. However, the growing emergence of direct-injected and turbocharged gasoline engines have made the fuel economy difference between gas and diesel engines much smaller than before. Seredynski said that regardless of fuel, the end goal is the same: maximum power from the minimum amount of fuel. The Ram 1500 Eco Diesel is the current full size pickup mileage champ at 20/28 mpg in EPA testing, but Ford's new 2.7L Eco Boost V-6 gas engine is likely not be far behind. Another enabling technology that has increased economy on both gas and diesel engines are transmissions with much higher gear counts, with six speeds now considered the bare minimum, just as eight-speeds and higher are starting to become the norm. Refinement: Gas, But Barely Diesel engines have evolved tremendously over the last 20 years in almost every area, but perhaps the most impressive strides have been made in the area of noise, vibration and harshness. In the '80s and '90s, it was not uncommon to have to turn your engine off in the drive-through so the cashier could hear your order. On some of today's trucks, the engine type is almost unnoticeable from the driver seat. The biggest enabler of this is vastly more refined injection technology, which has made diesels nearly the peer of their gasoline counterparts. In the case of direct fuel injection, the technology has had a different effect on gasoline and diesel engines...

...Diesel Locomotives – Efficiency in Motion Since the early 1900’s, diesel technology in locomotives has changed the railroad industry. Although the diesels were slow to catch on, the diesel locomotive proved to be more powerful, safer, more efficient and have less maintenance than steam powered locomotives. Today, modern diesel electric locomotives have further stretched the benefits of diesel technology. Incredibly, freight trains have increased their fuel efficiency by 80 percent over the past 25 years and today's locomotives can move a ton of freight more than 400 miles on a single gallon of fuel. With all the benefits regarding diesels, there is another source of inefficiency in the railroad that is often overlooked, the rail yard and switching terminals. The rail yards and switching terminal are traditionally the biggest culprits of air pollution and fuel inefficiency, presenting the greatest opportunities for further improvement. The Belt Railway Company of Chicago (BRC) is the largest intermediate switching terminal railroad in the United States. The BRC has 28 miles of mainline with more than 300 miles of switching tracks, allowing it to interchange with every railroad serving the Chicago rail hub. The Belt's Clearing Yards span a 5.5 mile distance among 786 acres, supporting more than 250 miles of track. The Belt Railway currently dispatches on a service-driven basis more than 8,400 rail cars per day. At Clearing Yard, employees are able to classify between...

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 it’s compressed, the fuel ignites. Compression is a huge part of the diesel process. When working...

...1. INTRODUCTION 1.1 History of IC Engines: The machines that produce power or energy are called engines. The engines work as prime movers meaning “producers of motion”. There are other machines which are run by prime movers. Engines have become well known these days because of widespread popularity of automobile – the cars, trucks, buses and motor cycles are machines that are used for transport almost by everybody and everywhere. Doubtless no other engineering wonder can claim such wider use and engines provide the power for automobile. There are of course other uses of these engines also. Engines in general are reciprocating and rotary, the latter are commonly recognized as turbines, though there are some which are not turbine. An engine which was first introduced perhaps used a hot air which expanded on top of a piston. It was steam at high pressure which was then used against the piston which was pushed and moved in a cylinder linearly. The engine piston was connected to a crank through connecting rod caused the crank to rotate about its axis. Thus rotary motion is generated. An engine would definitely need an expanding medium which will push the piston when expanding. The expanding medium will have to be at higher temperature and pressure. The heat required for increasing the temperature and pressure of expanding medium can be given to the medium outside the cylinder in which the piston moves. In such a case the engine is called...

...Euro 4 and Beyond –Role of Diesel Fuel Injection Systems Dr. Gerhard Ziegler General Manager (R&D and Application) Motor Industries Co. Copyright © 2004 SAE International ABSTRACT The Euro 4 emission norms can be achieved by the wellnd rd known 2 and 3 generation Common Rail Systems of BOSCH. The beyond Euro 4 emission legislation is a challenging goal for diesel engine manufacturers. Lowest emissions with highest engine performance, namely high specific power output, petrol like noise levels, benchmarking low fuel consumption and attractive costs are the targets for development activities of the future engines. Key for the success will be sophisticated fuel injection system which supports all the above mentioned targets. Therefore, BOSCH did launch very early a fundamental project defining the requirements for future injection systems with regard to mixture preparation, maximum injection pressure, rate shaping capability and multiple injections. Using several versatile prototype injection systems a comprehensive engine investigation was accomplished to optimise the system configuration to meet the above targets of diesel engines. Applying the criteria of performance, manufacturing robustness, lifetime durability and costs, the variety has been reduced to a hydraulically amplified diesel injection system, which works with hydraulically amplified injectors. This concept together with a potential evaluation for two different Euro 5 scenarios is given in this paper. Figure...

There are significant differences between diesel engines and gas powered engines. Diesel engine repair specialists are familiar with the types of problems associated with diesel engines - their parts are different, and therefore so is the diesel engine repair that may be needed. A diesel truck engine is comparable to the engine of a truck powered by gas. Although they are both internal combustion engines, there are several differences between the two. The primary difference is how the combustion takes place. A diesel truck engine has fuel...

...Diesel exhaust fluid (DEF) is the combination of ammonia and water. Diesel exhaust fluid is used in any vehicle with a diesel engine. Diesel exhaust fluid is used in all on road commercial diesel trucks beginning in 2007. There were four tiers of legislation passed for all new diesel motors with 174 horsepower and up which applies to trains and ships built after 2016. When the Clean Air Act was passed by the government diesel motors were required to meet strict emissions standards. Selective catalytic reduction is a technology that uses a urea-based diesel exhaust fluid (DEF) and a catalytic converter to significantly reduce nitrogen oxides (NOx). The SCR is the most current technology in meeting 2010 emission requirements. A light mist of...
