Abstract: The energy shortage and more strict environmental standards make the energy efficiency and environmental protection become the most important issues to be considered by shipping industry and shipbuilding industry. So a good marine diesel engine not only has to keep good dynamic and steady characteristics, but also has to improve fuel economy and minimize the emissions. In order to meet these requirements, it is necessary for the marine diesel engine model to predict its properties in the severe environmental conditions, such as load changing quickly. In the other hand, the model is one of the most important parts of the marine simulator for dynamic simulation and fault diagnosis. In the effort to find an alternative source of energy for diesel engines various solutions have been proposed, one of which is the use of biofuel blends as supplement or substitute for liquid diesel fuel. One of the main purposes is to find ecofriendly sustainable fuel. The efficiency, exhaust gas temperature, nitric oxide, carbon monoxide, unburned hydrocarbons and soot emissions are to be considered. Also, the use of previous mentioned blends as pilot fuel to be used with natural gas as primary fuel in dual fuel engine. Given that the experimental measurements cover a wide range of liquid diesel supplementary ratios without any appearance of knocking phenomena, the belief is strengthened that the findings of the present work can be very valuable if used to apply this technology on existing DI diesel engines.
