At present time, the environmental pollution of the world is one of the most urgent problem for all humanity. To reduce the pollution from the ships, there are many solutions to be used such as: modification of diesel engines, using bio-diesel fuel,... Using of bio-diesel as fuel for diesel engines was well-known, however the using bio-diesel fuel for the marine diesel engine also have been restricted, because of the technology of marine diesel engine or the other problems.
For laying the foundation of the applying bio-diesel fuel for the marine diesel engine in Vietnam conditions, the researcher have carried out a research on the combustion process of the bio-diesel B5 fuel in the small marine diesel engine in Vietnam conditions.
The GT POWER simulation software and MATLAB software have been used to simulate the combustion process of the small type marine diesel engine D243 at Vietnam Maritime University (VIMARU) when the engine used two kind of fuel: bio-diesel B5 and diesel oil (DO). And the experiment has been done on diesel engine D243 SONG CONG at the laboratory of the Internal Combustion Engine Division, Dynamic Mechanical Academic, Hanoi University of Science and Technology linked up with Chemical Technology Academic. Finally, we tested the experimental results for analyzing and evaluating theorical results.
The paper is indicating some theorical studying results of bio fuel combustion process in small marine diesel engine and comparing these results with the combustion process of DO using engine.
