A large population of diesel engine power plant that spread all over Indonesia will take part in increasing global warming. Using fuel efficiently will control the emission level subsequently reducing the greenhouse effect. One of the many techniques to utilize fuel efficiently is HCCI. HCCI application in a diesel engine is carried out using controllable electronic injectors. Design and building of an SD295 double cylinder diesel engine electronic controller using ATMEGA8535 had been conducted in this research. Principle of this control method is to vary the timing and amount of fuel injected directly to the combustion chamber. The timing of fuel injection is related to SOI (Start of Injection) and EOI (End of Injection). The amount of fuel injected is proportional to the duration of activated injectors from SOI to EOI, the longer the duration the more of fuel injected to the chamber. Performance of prototype of SD295 double cylinder diesel engine electronic controller using ATMEGA8535 as the result of this research had been validated using COM Engine Indicating instrument located in Internal Combustion Engine Laboratory P2 TELIMEK LIPI. Test results show that varying and setting of SOI and EOI were well executed by the control system.","PeriodicalId":232017,"journal":{"name":"2019 International Conference on Sustainable Energy Engineering and Application (ICSEEA)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121045706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To improve the VAWT performance, one of the influencing factors is blade design. The model of blade design will be affected by the output power. Therefore, the choice of blade design will be affected by the coefficient of power. The blade design was the airfoil of the type-H rotor of NACA 4212. Several empirical hypotheses obtained it through the practical experience subjected to use of the savonius blades. It will be shown in this study was to compare design a new type-H rotor VAWT blade using Computational Fluid Dynamic (CFD) software. The novel blade design was upper-curve H-blade of NACA 4212. It showed the result of the analytical analysis to be compared with the same upper-curve inverted blade, and with the upper-lower blade. The results of the performance comparison of numerical analysis, the upper-curve blade has a better power coefficient than the other types. Therefore, the upper-curve blade has the highest power output.","PeriodicalId":232017,"journal":{"name":"2019 International Conference on Sustainable Energy Engineering and Application (ICSEEA)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121275772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
