Characterisation of Large Gas and Dual-fuel Engines
- 115 Downloads
Engines burning gas or combinations of gas and liquid fuels have become popular in recent years, but due to lack of an established nomenclature designations have become somewhat confusing. In order to facilitate communication between engine builders and users, a research project at Delft University of Technology has identified nine different engine types, each with unique properties which strongly affect their emissions and operational behaviour.
While gas engines are arguably more environmentally-friendly than the diesel engines, natural gas itself is some way from being a green energy source. However, before a truly sustainable industry can be achieved, a transitional solution is needed to cope with ever-stricter emissions regulations and this is where the advantages of gas engines lie. They are readily available, economically viable and operate well on biogases as well as natural gas.
