Explain The Thermodynamic Process Of Diesel Cycle

The Cummins diesel engine was manufactured in the year 1919 by its creator Clessie Cummins. The Cummins was put in a variety of vehicles and the most common are in the dodge ram 2500, 3500, 4500, and 5500 series rams. It is also put into more heavy-duty trucks such as Peterbilt semis. The reason people choose Cummins over Chevy’s Duramax or Ford’s Powerstroke is because Cummins’ are built to last longer meaning they can go more hours without maintenance. The Cummins diesel engines have several different designs, and a number of different models, and assembling one takes money, time, effort, and knowledge.

After many years of trial and error, a combination of inventors and engineers developed a practical, effective internal combustion engine that greatly affected the world. This paper will give opposing views on the background and analyze the effects it had on transportation and the environment.

The continuing rotation of the crankshaft drives the piston back up, ready for the next cycle. The piston moves in a reciprocating motion, which is converted into circular motion of the crankshaft, which ultimately propels the car. Gas engines usually have about the same about of horsepower as they do torque. The diesel engine usually has twice as much torque as it does horsepower, thus it is the better hill climber and load carrier.

A typical day for a diesel mechanic involves troubleshooting and repairing any problems with a diesel engine that may come their way. Some duties that diesel mechanics may do on a daily basis include using checklists to aid in the inspection of

Equally important as the air, is the fuel going into the cylinder. Fuel starts off in the gas tank of the car and then gets pumped into the fuel lines by the fuel pump. The fuel goes through the fuel lines and into the fuel rail. Attached to the fuel rail are electronically controlled injectors (one per cylinder), which are controlled by the mass air sensor. The mass air senor regulates how much fuel is necessary to mix with the air to achieve the ideal air to fuel ratio. The injectors "spray" into the cylinder at synchronized times mixing with air and eventually resulting in combustion.

2. “ Because of their efficiency and durability, diesel engines have become the standard in powering trucks and buses. Other heavy vehicles and mobile equipment, including bulldozers and cranes, are also powered by diesel engines, as are many commercial boats, and some passenger cars and trucks. Diesel technicians handle many kinds of repairs. They may work on a vehicle’s electrical system, make major engine repairs, or retrofit exhaust systems with emission control systems to comply with pollution regulations. Diesel engine maintenance and repair is becoming more complex as engines and other components use more electronic systems to control their operation. For example, fuel injection and engine timing systems rely

To effectively capture the energy lost from a diesel engine exhaust pressures, the turbocharger was implemented to boost the power of engine and thereby increasing the fuel efficiency. The majority of the heat energy from the exhaust and coolant has yet to be captured and utilised. There has been many challenges to recovering the heat as the low grade heat from the diesel engine cannot be

Observing the data, it can be seen that there is a significant increase in the amount of energy diesel + hexanol (C6) produced (in kJ/g). Theoretically, only 5.2 kJ/g was expected to be released, however the hexanol displayed synergistic effects, as an extra 1.1

In 1872 an American by the name of George Brayton invented the first commercial internal combustion engine that was liquid fueled.(“Diesel Engine.”) In the 1890’s Rudolph Diesel invented the first compression ignition engine (Jääskeläinen).

The invention of the Diesel engine changed the way people lived in the industrial revolution. It had countless long term consequences both positive and negative. Firstly, the Diesel engine helped businesses, and people selling goods flourish in their businesses. The engine not only helped the selling and accessibility of goods in the short term, it also aided the economy in the long term. The invention of the Diesel engine meant that goods were more accessible and money could be gained quicker. The Diesel engine has some very terrible long term effects. Still today the diesel engine is one of the biggest producers of pollution. Studies have shown that a "Diesel engine emits four times more toxic pollution than a bus."(Carrington, D. (2015).

The internal combustion engine is vital to the modern automobile. An internal combustion engine uses an explosive combustion of fuel to push a piston within a cylinder. The piston moves to turn a crankshaft that is connected to the car's wheels through a drive shaft. Without an engine a car could not move. The internal combustion engine has a long history of how it was improved and redesigned, without which the car would wouldn’t be able to function.

Secondly, as the Marine Executive goes on to pronounce, that although natural gas engines look good from an emissions standpoint, the creation of new electric systems are allowing the diesel engines of the industry to remain competitive and viable options. Caterpillar is currently at the forefront in the field of diesel electric propulsion and increasing the power efficiency in comparison to traditional direct-drive diesel systems. Where in traditional diesel systems the engine is connected directly to the propulsion line, in electric propulsion systems, the engine is connected to an electric generator. From here the power is then relayed through a switchboard, transformer, frequency converter, electric motor and, ultimately, the propeller

An automotive engine extracts work from its chemical fuel by burning that fuel inside its cylinders and making the resulting burned gas do work on the engine. Most engines have at least four cylinders, each of which requires four strokes of the piston to extract work from the fuel. During the induction stroke, a piston moves out of the cylinder and the fuel and air enter it. During the compression stroke, the piston moves into the cylinder, compressing this fuel-air mixture to high density, pressure and temperature. An electric spark then ignites the mixture and converts it into extremely hot burned gas. During the power stroke, the piston again moves out of the cylinder while the hot gas does work on it. This work is what powers the car. Finally, during the exhaust stroke, the piston moves into the cylinder and

Diesel mechanics would be without a job If it were not for Rudolf Diesel. Diesel attented the Polytechnic High School of Germany in 1878, there he was disturbed by the low efficiency of gasoline and steam engines (Brian). Diesel was a pioneer in the industrial industry with his new fuel efficient and power maximizing engine. Rudolf Diesel put a patent on an engine a

Engineering: [a] diesel engine is an internal combustion engine in which the chemical energy of fuel is transformed into thermal energy of the cylinder charge, in consequence of the self-ignition and combustion of fuel in the engine cylinder after compression of the air charge in the cylinder (p1
