Frequently Asked Questions

For students

If I order a paper sample does that mean I'm cheating?

Not at all! There is nothing wrong with learning from samples. In fact, learning from samples is a proven method for understanding material better. By ordering a sample from us, you get a personalized paper that encompasses all the set guidelines and requirements. We encourage you to use these samples as a source of inspiration!

Why am I asked to pay a deposit in advance?

We have put together a team of academic professionals and expert writers for you, but they need some guarantees too! The deposit gives them confidence that they will be paid for their work. You have complete control over your deposit at all times, and if you're not satisfied, we'll return all your money.

How should I use my paper sample?

We value the honor code and believe in academic integrity. Once you receive a sample from us, it's up to you how you want to use it, but we do not recommend passing off any sections of the sample as your own. Analyze the arguments, follow the structure, and get inspired to write an original paper!

For teachers & parents

Are you a regular online paper writing service?

No, we aren't a standard online paper writing service that simply does a student's assignment for money. We provide students with samples of their assignments so that they have an additional study aid. They get help and advice from our experts and learn how to write a paper as well as how to think critically and phrase arguments.

How can I get use of your free tools?

Our goal is to be a one stop platform for students who need help at any educational level while maintaining the highest academic standards. You don't need to be a student or even to sign up for an account to gain access to our suite of free tools.

How can I be sure that my student did not copy paste a sample ordered here?

Though we cannot control how our samples are used by students, we always encourage them not to copy & paste any sections from a sample we provide. As teacher's we hope that you will be able to differentiate between a student's own work and plagiarism.

5000 words 21 5250 words 22 5500 - Model predictions established that by mixing the reduced-friction designs, a decrease in piston ring pack friction of % might be achieved, without a rise in blowby, put on, or oil consumption.(cont.) Experimental results conducted on the full-scale gas power generation engine supported the model predictions for that low-tension oil control ring design. In the process of designing internal combustion engine, piston ring plays an important role in fulfilling the requirements of camber gas sealing, friction reduction and lubrication oil consumption. The goal of this thesis is to have a better understanding of the ring behaviors under different working conditions in a structural Dian Xu. Piston rings are metallic gaskets whose functions are to seal the combustion chamber against the crankcase, to transmit heat from the piston to the cylinder wall, and to regulate the amount of oil present on the cylinder sleeve.

The Peoples Century - The various piston ring designs also influence the pressure distri - bution inside the sealing system. In the case of new piston rings of a gastight design, the entire pressure difference is typically sealed by just one or two sealing elements at the ends of the sealing system 3, 4. Abstract: The lubrication of the piston ring has been an important research matter for many years because it is generally accepted that the interaction at the ring-cylinder wall interface provides. 3) Structural design of piston rings using FEA is not studied adequetly. Hence, design validation can be caried out using commercial FEA tools such as ANSYS, Abaqus, etc. ACKNOWLEDGMENT It gives me great satisfaction in submitting this paper on the title “A Review on Design of Piston Ring.” I would like to take this opportunity to express my.

The design procedure of piston consists of the following parameters:  Thickness of piston head (t L)  Heat flows through the piston head (H)  Radial thickness of the ring (t 5)  Axial thickness of the ring (t 6)  Width of the top land (b 5)  Width of other ring lands (b 6)  Maximum Thickness of Barrel (t 7). Currently piston ring designers rely on crude formula and experience to design ring free shape and twist chamfers with little consideration of the consequences of the ring reaction in a distorted bore under dynamic loadings during engine operation.

The rig was designed so that standard HDDE production piston rings and cylinder liners could be easily mounted, and so that piston ring friction could be measured without influence. piston rings are introduced. Thus rings are designed to be in tight contact to the cylinder wall, and is subject to friction and wear as it travels up and down the cylinder wall.

The pivoting design of the piston allows coolant to be introduced through the pivot point on one side of the piston, travel through a channel under the combustion chamber, and exit through the second pivot point. This design was later improved when Miller redesigning the ring to be a looser fit by machining the ring thinner and lighter to allow gas pressure behind the ring to change with the pistons’ movement [3]. These two designs are the earliest documented cases of the piston ring-pack and are considered to be forerunners of modern ring-pack design.

The piston ring preferably has an outer peripheral surface that includes a sealing land with a nitride hardened surface to resist wear during the service life of the piston ring. A tapered surface is also provided on the outer peripheral. Piston and piston ring designs thus face constant challenge to provide proper control of blow-by, oil consumption, friction, wear, and oil consumption.
