Abstract
In the future, when traditional fuels are exhausted, biofuels are the alternative candidate. The more developed the world, the greater the demand for fuel, while the natural resources are not unlimited. Therefore, the search for a new fuel source is more plentiful, more sustainable, less polluting, greenhouse effect and environmentally friendly as well as an opportunity to manage natural resources. In the maritime industry, most of the ships currently are using diesel engines as a propulsion device for propeller spinning, hybrid generators or other equipment. The main solution is to accelerate the research and deployment of applications into practical exploitation and encourage the use of biofuels. To enhance the building of material foundations, the training of human resources, the improvement of the system of policies, legal documents and the enhancement of international cooperation in biofuels development, raising public awareness. on the development of biofuels.
Highlights
Marine diesel engines are internal combustion engines, the combustion of diesel fuel occurs in the combustion chamber when the piston approaches the upper dead zone in the compression phase, fuel is injected, blended, evaporated and burnt under the effect of temperature and high pressure of compressed air [1],[2]
Because of the advantages of a diesel engine compared to a gasoline engine such as higher engine efficiency, cheaper fuel, use of fuel mixture and quality is not too rigorous diesel engines
For medium and low speed diesel engines, the fuel delivery time will be longer than the high speed motor and occurs from 0.0083 to 0.044 s. With this type of diesel engine, it is possible to use HFO with lower quality and price. With specifications such as marine diesel engines are usually quite easy to use in the use of different fuels, from distillate fuel to HFO
Summary
Marine diesel engines are internal combustion engines, the combustion of diesel fuel occurs in the combustion chamber when the piston approaches the upper dead zone in the compression phase, fuel is injected, blended, evaporated and burnt under the effect of temperature and high pressure of compressed air [1],[2]. Because of the advantages of a diesel engine compared to a gasoline engine such as higher engine efficiency, cheaper fuel, use of fuel mixture and quality is not too rigorous diesel engines It is widely used in many branches and fields. There are other research projects such as the production of new fuel, biofuel replacing a traditional and friendly fuel, without environmental pollution, greenhouse effect [9],[10] These studies have been studied and applied by many countries, organizations, and scientists around the world with the aim of being environmentally friendly and reducing harmful emissions to the environment [11]. According to the general development trend above In the world as well as in Vietnam, in the few years, the use of new generation of small-sized diesel engines is strongly developed thanks to the advantages such as fuel economy, smooth operation, and no pollution. The introduction of new fuels and biofuels into diesel engines is a small diesel engine
