This assignment is worth20%of the overall assessment for this module. Section B: Student(s) to complete Student ID numberYear Code Notes for students• For undergraduate modules, a score above 40% represent a pass performance at honours level.• For postgraduate modules, a score of 50% or above represents a pass mark.• Late submission of any item of coursework for each day or part thereof (or for hard copy submissiononly, working day or part thereof) for up to five days after the published deadline, coursework relatingto modules at Levels 0, 4, 5, 6 submitted late (including deferred coursework, but with the exception ofreferred coursework), will have the numeric grade reduced by 10 grade points until or unless thenumeric grade reaches or is 40. Where the numeric grade awarded for the assessment is less than40, no lateness penalty will be applied.• Late submission of referred coursework will automatically be awarded a grade of zero (0).• Coursework (including deferred coursework) submitted later than five days (five working days in thecase of hard copy submission) after the published deadline will be awarded a grade of zero (0).• Regulations governing assessment offences including Plagiarism and Collusion are available fromhttps://www.herts.ac.uk/about-us/governance/university-policies-and-regulations-uprs/uprs (pleaserefer to UPR AS14)• Guidance on avoiding plagiarism can be found here:https://herts.instructure.com/courses/61421/pages/referencing-avoidingplagiarism?module_item_id=779436• Modules may have several components of assessment and may require a pass in all elements.

School of Physics, Engineering and Computer SciencePage 3 of 5ASSIGNMENT BRIEFING SHEETIntroductionIn this assignment you are given a four-stroke single cylinder engine specifications and in-cylinderpressure data for the engine using gasoline and E50. The performance of these fuels needs to becompared to each other using the data provided and the lecture materials. The results are to bepresented in a report and submitted to Studynet.Report, article contentStudents expected to:• Create a research paper like document• Carry out the necessary calculations in Excel or MATLAB• Compare the performance of gasoline and E50 (power output, Torque, SFC)• Show pressure curves with some analysis• Obtain mass fraction burned curves• Compare physicochemical properties of E50 and gasoline in a Table• Compare ignition delay time and laminar flame speed of both fuels in engine relevantconditionsThe structure of the report should follow as below:The abstractAn abstract is a brief summary of a research article, thesis, review, conference proceeding or anyin-depth analysis of a particular subject and is often used to help the reader quickly ascertain thepaper’s purpose. The abstract must be able to stand on its own: overall aim and some details mustbe given, at the end of it some of the main findings should be shown.School of Physics, Engineering and Computer SciencePage 4 of 5IntroductionIntroduce the reader to the followings:• Why is the content of the paper is important (must support your statement with references.• What is that the methodology, questions, proves, argues…• Make your contribution clear, could be a separate short section (could be analytical type withhypothesis)Figure 1. Caption example, add a short descriptive caption, if the image is not your work thenyou can write: adopted from [x]Results and discussionThese can be separated or presented together depending on personal preferences and on the topic.If it’s an experimental type report then evaluation of errors is vital. This can be done separately ortogether with the results.Present your findings, discuss if these meet the expectations. It is important that you cross-comparethe values with some already published values.School of Physics, Engineering and Computer SciencePage 5 of 5At a master level for marks over 70, it is expected that student carry out some advanced analysisthis can include:• statistical analysis of data and correct presentation• detailed analysis of p-V diagram: imep, bmep, fmep.• Heat release rate calculation from pressure curves• Mass fraction burnedConclusionsWhen you write a paper, you always end by summing up your arguments and drawing a conclusionabout what you’ve been writing about. The phrase in conclusion means “finally, to sum up,” and isused to introduce some final comments at the end of a speech or piece of writing. It usually startswith restating the main argument, add a brief description of methodology, show your results.References and websites accessedInformation obtained from books or journals must be referred to in the text by a superscript referencenumber.An example is:[1] PITT, C.W. ‘Sputtered Glass Optical Waveguides’, Electronic Lett.1973 9 pp 401- 403.Report, article formatYour report should have a typical research article format, make sure you use third person andpassive grammar. Start with the title and a single column abstract then the rest of the article (e.g.Introduction, Results, Discussion, Conclusion and References) should have a double column format(not mandatory). There are no strict formatting requirements but make sure high quality, explainingimages, comparison tables, graphs are included. The maximum word count for the abstract is 150words and for the whole of your article is 3000 words (including references).
