Sažetak Raspoloživost propulzijskoga dizelskog motora u pogledu snage ili bilo koje druge značajke, pri raznim eksploatacijskim uvjetima utvrđuje se proračunima, a potvrđuje empirijskim metodama. Računalno-simulacijski modeli veoma su važni za takve analize. Računalno-simulacijski model brodskoga propulzijskog dizelskog motora osnovan na matematičkom modelu, prikazan je u ovom radu [1]. Model je upotrijebljen za analizu stacionarnih i dinamičkih uvjeta rada sporohodnoga propulzijskog dizelskog motora s prednabijanjem i brodskoga vijčanog propulzora s nepomičnim krilima. Model je izrađen uz uporabu računalne aplikacije MATLAB 7.0.4.SIMULINK, na osnovi detaljnoga matematičkog nultodimenzionalnog modela. U ovome radu navedeni model je poslužio za raščlambu utjecaja promjene snage u pojedinim cilindrima na radne značajke motora. Promjena snage simulirana je prekidanjem dobave goriva jednome cilindru pri različitim opterećenjima motora i različitim ograničenjima poluge goriva. Analizom rezultata simulacije utvrđene su granice radnih značajka motora i sigurna pogonska stanja. Ključne riječi: dizelski motor, simulacija, dobava goriva.

An extracellular nuclease produced by Staphylococcus aureus1-3 has been shown to contain 149 amino acid residues (mol wt, 16,807) and to lack both sulfhydryl groups and disulfide bonds (Fig. 1).3-5 The enzyme catalyzes the cleavage of both DNA and RNA to yield 3’-nucleotides.2s 3 The absolute requirement for Ca++ l* 2s 6 may be explained by the interdependency of Gaff and nucleotide binding to ...

متن کاملBenthic grazing in a eutrophic river: cascading effects of zoobenthivorous fish mask direct effects of herbivorous fish
Benthic grazing strongly controls periphyton biomass. The question therefore arises whether benthic grazing could be used as a tool to reduce excessive growth of periphyton in nutrient-enriched rivers. Although benthic invertebrate grazers reduce the growth of periphyton, this is highly context dependent. Here we assessed whether the only obligate herbivorous fish in European rivers, the common...

Previous studies (1) have indicated that the repertoire of murine T cells specific for a potentially complex protein antigen is in fact specific for a limited number of antigenic epitopes on that antigen in association with a given Ia molecule. Since those studies generally analyzed responses to antigens that differ in only a few amino acids from homologous murine molecules, it was possible tha...
