DISCUSSION ABOUT RESEARCH PAPERA cold-start method and analysis for internalcombustion engines particularly using a renewable fuelYiding Cao and Deqi Chen

International Journal of Energy ResearchVolume 35, March - 2011INTRODUCTIONAlternative fuels such as ethanol and methanol are considered to be renewable fuelsHowever, an internal combustion engine operating on ethanol or methanol could encounter cold-start problems, due to a very small cetane number, large latent heat, and high ignition temperature .A NEW COLD-START/WARM-UPMETHODThe success of a cold start are depends on the charge temperature and ignition delay.To increase the charge temperature, a novel cold-start method is introduced, which may cold start even pure ethanol or methanol without the need for preheating and distillation

ANALYSIS OF RESEARCH PAPERIMPACT FACTORImpact factor is generally used for journals.Above discussed research paper is taken from International Journal Of Energy Research.According to Google scholar data total number of citation given by other journals from this journal in year 2011 & 2012 are 47. A = 47 and number of research paper cited by other journal in year 2013 is 17 . B = 17

So, impact factor of International Journal Of Energy Research for year 2013 is = 47/17 = 2.7642. H FACTORH factor is generally defined for author or researcher.According to Google scholar data Mr. Yiding Cao has presented three research paper up to 2013 and his one research paper get one citation.So H FACTOR for Mr. Yiding Cao is 1 .3. CRITICAL REVIEW INTRODUCTIONIn above discussed research paper author have clearly define the research problem of cold start in renewable fuel engine and introduce the variable which are affecting the problem. They also provide sufficient literature review.METHEDOLOGYGenerally cold start problem can be solved by physical modification only and author selected a cheap method of modification. They does not include the data of instrument which are used for measuring the pressure and temperature. They does not include the starting power requirement in modified setup.RESULTS They have presented their findings clearly. They have also given reference of other method and proven their method superior.

DISCUSSIONThey have not considered any limit for their research.Their research suggest further direction of research because they assume that some of the charge after compression is present Inside the cylinder but actual case may be different. They have emphasized on practical approach of research paper4. STRENGTH OF RESEARCH PAPERAbove discussed research paper clearly identify the problem of cold start and factor affecting it.They have proven superiority of their method by providing table of inlet temperature and final temperature.5. RESEARCH GAPAuthors have used completely mechanical system for problem solving.But now a days due to availability of electronic control unit inside the car fuel heater and temperature sensors are used to measure the inlet temperature and heating a fuel up to specific temperature in very short time. 6. WHAT CAN BE FURTHER RESEARCHEDAuthors have made a assumption that during first compression some of the charge is present inside the cylinder.But in actual case condition may different. So, one can make a research that after compression stroke how much amount of charge remain outside the pre chamber and what are the factors affecting it.PART III

OTHER THEORIES1. PROBLEM STATEMENT IDENTIFICATIONSTEPSSince a research problem is usually something you have some knowledge of, that subject is often a good starting point .Now you have to talk with your teacher or counselor about your research problem so you may find brief idea about your problem.Narrowing or clarifying your research problem.Find the literature available for your research problem and be clear about the research gap.Now again narrowing your problem statement.2. VALIDATION OF RESEARCH PAPERValidation is the measure of how the theoretical studies correlate with the practical problem and other theoretical approach. Construct Validity TestThis test refers to the measure to operationalization of theoretical approach.

Convergent Validity TestThis test refers to degree which theoretical approach is used to derive another theory.

Content Validity TestDuring practical, researcher take a reading with different inlet value.Content validity test refers to measure that this inlet value contain behavior of whole group or not.THANK YOU
