Abstract
Motori s dvojnim gorivom su motori koji mogu raditi na dva goriva, prirodni plin i dizel. Što se tiče dizelskih goriva oni su mješavina različitih destilata od kojih su lako i teško gorivo. Laka goriva su jako slična dizelskom gorivu, dok teško gorivo se razlikuje od dizelskog po svojoj viskoznošću, treba ga grijati da bi bio viskozniji i imao sposobnost protjecanja. Teško gorivo se u brodskoj industriji koristi jer je jeftiniji od dizela. Ukapljeni prirodni plin je pročišćeni prirodni plin koji se ohladi u tekuće stanje radi lakšeg transportiraja. Plinovita goriva u pomorstvu se uvode radi smanjenja emisija. Motori na dvojno gorivo imaju mogućnost rada na dva goriva, i prebacivanje goriva iz dizelskog režima rada u plinoviti režim rada je neprimjetan i nema gubitka snage na motoru. Najpoznatiji motori s dvojnim gorivom su opisani u ovom radu od kojih su ME-GI, DFDE i XDF. ME-GI motori se pokreću na dizelsko gorivo, a prijelaz na plinski režim rada može se dogoditi pri opterećenju motora od 10%. Teško gorivo i dizelsko gorivo mogu se koristiti kao pilot gorivo. Kao što je iskustvo pokazalo ME-GI motori smanjuju emisije CO2, NOx, SOx. Nadalje DFDE propulzija pruža jednostavniji izgled glavnog motora na brodu, ima četiri do pet glavnih motora, koji su svi istog tipa, pokreću alternatore koji generiraju električnu energiju za sve potrošače na brodu. I na kraju XDF motori na dvojno gorivo koriste plin ubrizgan pod niskim tlakom i zapaljuju se malom količinom tekućeg pilotskog goriva.
Abstract (english)
Dual-fuel engines are engines that can run on two fuels, natural gas and diesel. As for diesel fuels, they are a mixture of different distillates, of which they are marine gas oil and heavy fuel oil. Marine gas oil is very similar to diesel fuel, while heavy fuel oil differs from diesel in its viscosity, it needs to be heated to be more viscous and have the ability to flow. Heavy fuel is used in the shipping industry because it is cheaper than diesel. Liquefied natural gas is a purified natural gas that cools into a liquid state of easier transport. Gaseous fuels in maritime affairs are introduced to reduce emissions. Dual-fuel engines have the ability to operate on two fuels, and the transfer of fuel from diesel mode to gaseous mode is inconspicuous and there is no loss of power on the engine. The most famous dual-fuel engines are described in this thesis, of which are ME-GI, DFDE and XDF. ME-GI engines are powered by diesel, and the transition to gas mode can occur at an engine load of 10%. Heavy fuel and diesel fuel can be used as pilot fuel. As experience has shown ME-GI engines reduce CO2, NOx, SOx emissions. Furthermore, DFDE propulsion provides a simpler look for the main engine on board, it has four to five main engines, which are all of the same type, powering alternators that generate electricity for all consumers on board. And finally, the dual-fuel XDF engines use low-pressure injected gas and ignite a small amount of liquid pilot fuel.
