Methodology for Periodic Compliance Control of Composite Reservoirs Installation in Motor Vehicles
The paper points out the problem of periodic compliance control of composite reservoirs installation in motor vehicles and necessity of designing methodologies in this field. The survey indicated that with expert systems application periodic compliance of composite reservoirs installation can be achieved. The paper presents the design of an expert system for visual control of composite tanks for storing compressed natural gas as a fuel for motor vehicles, using a shell expert system as a tool to design the knowledge base. The knowledge base is designed using production rules. The expert system is tested on a concrete example. The research results point to the possibility of periodical compliance control of composite reservoirs installation in motor vehicles using designed knowledge base. Also, the quality of visual control, reducing the time for analysis and reasoning on the state of composite reservoirs and auxiliary equipment for storing compressed natural gas as a fuel for motor vehicles, is achieved using the designed expert system.Advanced Engineering System
Combustion characteristics of several types of biofuel in a diesel engine
Interesovanje za alternativna goriva koja bi se koristila za pogon motora sus je veoma veliko u Äitavom svetu. Zato se istraživanja vezana za ovu problematiku vrÅ”e u mnogim vodeÄim svetskim laboratorijama za motore. Razlog ovog interesovanja su dostupnost ovakvih goriva, povoljne ekoloÅ”ke karakteristike i pozitivan uticaj na ekonomije zemalja koje ovakva goriva mogu da proizvode. U predmetnom radu se daje deo rezulta veoma kompleksnih i dugotrajnih istraživanja dinamike procesa sagorevanja kod dizel motora pogonjenog metilestrima biljnih ulja i to otpadnog palminog jestivog ulja, sojinog ulja i ulja uljane repice. PoreÄenje promena u radnom procesu motora, pre svega procesu sagorevanja, je vrÅ”eno pri sinhronizovanom radu motora na uobiÄajenim standardnim dizel gorivom mineralnog porekla. Analizom zakona (toka) sagorevanja svakog pojedinaÄnog goriva, utvrÄeno je da postoje razlike koje nisu velikog karaktera, iz Äega se može zakljuÄiti da su goriva proizvedena iz biljnih ulja, a po važeÄem standardu, veoma kvalitetna goriva za pogon dizel motora. Ovo daje moguÄnost naroÄito poljoprivrednim gazdinstvima da samostalno proizvode deo potrebnog goriva sa sopstvenih zemljiÅ”nih parcela uz uslov da poseduju odgovarajuÄu opremu za proizvodnju biodizela.Alternative propulsion fuels for diesel engines were highlights for a variety of research activities within a large number of R&D labs in the world. Curiosity, as well as basic interest in alternative fuel has been immense because of its reproducibility, renewability, as well as good ecological characteristics. Another reason for this interest is a favorable impact on the economies of the countries engaged in their production, by processing that kind of bio fuel. This paper presents the results of testing and research of the three types of alternative fuel gained from bio oil. Analyses and comparison of the dynamics of combustion process of these alternative fuels were done in relation to the reference diesel fuel. Burning process of methyl esters rapeseed (RME100), soya oil (SME100), waste cooking palm oil (PME100), as well as of regular Euro diesel fuel were investigated. It was found that these fuels were highly usable in diesel engines if they had been produced according to a proper standard procedure under standard EN 14214. The application of bio fuel is also very interesting for the propulsion of agricultural engines and machinery, because it enables the individual farming of bio fuel products necessary for the appropriate own machinery
