Unit - injector (PDE/UIS) Diesel engine injection system
No full textU radu je analiziran sustav ubrizgavanja pumpa-brizgaljka (PDE/UIS) kao i prednosti i nedostatci, u odnosu na sustave, koji su također u upotrebi. Analizi sustava ubrizgavanja prethodio je detaljno opisan princip rada, kao i stvarni radni ciklus 4-taktnog Dieselovog motora. Potom su analizirane i različite vrste sustava za ubrizgavanje goriva (direktno i indirektno ubrizgavanje), princip rada i svi bitniji sastavni elementi potrebni za rad tih sustava. Kroz vremenski slijed događaja, važnih za usavršavanje sustava za ubrizgavanje, kroz povijest, prikazan je pregled razvoja istih. Detaljnije su opisani svi sustavi ubrizgavanja koji se koriste kod Diesel motora za komercijalne svrhe od mehaničkih do potpuno elektroničkih. Tu se ubrajaju, već zastarjela tehnologija mehaničkog reguliranja sustava za ubrizgavanje goriva i tehnologija elektroničkog reguliranja sustava, kao novija tehnologija, s kojom su postignute puno bolje karakteristike i performanse, u odnosu na sustav s mehaničkom regulacijom. U elektroničke sustave regulacije ubrajaju se: sustav ubrizgavanja pumpa-brizgaljka (PDE/UIS), razdjelna visokotlačna pumpa sa potisnim aksijalnim klipom, razdjelna visokotlačna pumpa sa radijalnim klipovima, i Common Rail (CR).
U sustavu ubrizgavanja pumpa-brizgaljka (PDE/UIS), gorivo se u cilindar motora ubrizgava direktno, a sustav je karakterističan po tome što se jedinstvenim sklopom pumpe i brizgaljke postižu visoki tlakovi tijekom ubrizgavanja goriva u cilindar, te mu je ovo jedna od najvećih prednosti u odnosu na ostale sustave.Unit injector system (PDE/UIS) is analyzed in use, his pros and cons compared to rest of the systems. Before the whole analyze, work principles and real work cycle of 4-stroke Diesel engine is shown. Different types of injecting systems (direct and indirect injecting), how they work and all essential elements required are being analyzed. Order of important achievements of development systems for injecting through history is being showed. All systems of injecting which are being used in Diesel engine from commercial purposes, all the way from mechanical to complete electric are described in more detail. There is mechanical regulation of system of injecting fuel which is outdated technology by today standards, and electronic regulation as new technologies which possess much better characteristics and performances compared to mechanical regulation. Electronic regulations possess distribution high pressure pump with thrust axial clip and electric regulation of diesel engine, distribution high pressure pump with radial clips, pump- injector system of injecting and Common Rail system of injecting as a system which achieves best results and which is being most used in todays time. Pump injector (PDE) is system in direct injecting fuel in engine cylinder, he is known for his unique pump set- injector which allows high pressure injecting, which is main advantage of the system
Yield comparison of two species of spice pepper (Capsicum annum L.) breeded with two breeding forms
No full textZa potrebe ovog rada provedeno je istraživanje na dvije vrste začinske paprike; Palotaš F1 i Szegedi 20. Istraživanje je imalo za cilj utvrditi prinos obzirom na sortu paprike i uzgojni oblik. Što se tiče uzgojnih oblika rađen je uzgojni oblik bez zakidanja zaperaka (grmoliki tip) i drugi tip uzgoja bio je uzgoj na četiri grane. Primijenjeni su svi potrebni agrotehnički zahvati za uzgoj ekološke začinske paprike (priprema tla u jesen, predsjetvena obrada, malčiranje navodnjavanje kap na kap i korištenje ekoloških sredstava zaštite). Obje sorte kod kojih je primijenjen „uzgojni oblik na četiri grane“ su ravnomjernije dozrijevale. Najveći urod dala je sorta Palotaš F1 kod koje je korišten uzgoj na četiri grane.For the purposes of this paper, two types of hot peppers were examined, Palotas F1 and Szegedi-20. The aim of the study was to determine the yield in relation to the type of pepper and to the type of cultivation. Regarding the cultivation forms, the cultivation form was carried out without breaking the constipation (shrubby type), and the second type of cultivation was the cultivation on four branches. All necessary agrotechnical measures for the cultivation of organic spice pepper were applied (soil preparation in autumn, cultivation before sowing, mulch drip irrigation and use of ecological protection agents). Both varieties, with the growth form „the four branches“, ripened more evenly. The Palotaš F1 variety, which was grown on four branches, achieved the highest yield
The relationship between the value of a football team and ticket prices on the example of the FA Premier League
No full textU radu se nastojalo istaknuti i objasniti značaj marketinga u svim svojim segmentima, a posebice kada je riječ o sportskom marketingu i njegovom utjecaju na nogomet i nogometnu industriju, na primjeru FA Premier lige. Osobito je ovaj trend vidljiv kod iznimno bogatih klubova čije financijske mogućnosti u mnogome nadilaze mogućnosti onih drugih, znatno „siromašnijih“ klubova, iako se natječu u približno istom rangu natjecanja. U ovome radu, iz sfere sportskog marketinga, na utakmicu će se gledat kao uslugu koja mora zadovoljiti određene strandarde tržišta i potrošača kako bi ostvarila prodaju svih vrsta sportskih proizvoda, što bi moglo imati značajan utjecaj na egzistenciju nogometnih klubova. Može se zaključiti da na povezanost vrijednosti nogometne ekipe i cijene ulaznica utječe jako puno faktora i varijabilnog je karaktera, barem iz promatranog primjera FA Premier lige.In the paper emphasis is placed on highlighting and explaining the significant meaning of marketing through all of its segments, especially those involved in sports marketing and its great influence on football and entire football industry, using the example of FA Premier League. This tendency is most obvious with the extremely wealthy clubs with financial opportunities far beyond those of „poorer“ clubs, although they may be competing in a similar, even same, division. In the paper, from the point of view of sports marketing, football match will be regarded as a service which has to fulfil certain standards, set by market and consumers, in order to succeed in selling all kinds of different sporting products, what could have a significant impact on the existence of football clubs. It is easy to conclude that correlation between the value of a football team and ticket prices is influenced by a number of factors and, in addition, tends to show varying characteristics, at least when observed using the FA Premier League as an example
