To establish a long-term sustainability of biodiesel to fulfill the quest for renewable fuel resources for the countries has low or no fossil fuels reserves. The energy resource meets to its limited capacity, alternative new energy resources must be explored such as the introduction of biodiesel as an alternative energy resources of petroleum products. The present research work is a 90-hour long-term endurance test performed with B30 sample (biodiesel 30% + 70% diesel) fueled with modified investigation performance, sound pressure level and engine durability. Special attention has been given to certain phenomena affecting the life of the engine, the formation of deposits and its performance. Experimental results of this research work demonstrated that the modified diesel engine could be efficiently performed with the B30 fuel sample.

The paper presents the results of simulation of marine diesel engine fuel injector malfunction and its effects on engine vibration. The work includes the analysis of the engine internal forces and their mathematical models. Simplifications are proposed to allow analyzing the system in one degree of freedom. The results of vibration simulations for the model with efficient fuel system and improperly adjusted injector are also presented. The comparison of simulation results with vibration measurements on the engine was also performed, the diagnostic model was identified and simulation errors were calculated. The complexity of other internal and external interactions is the subject of other studies by the authors. The paper analyzes only the effects of energy dissipation - vibration as a symptom of changes in the technical condition.

With the increasingly stringent requirements of diesel engine fuel consumption and pollutant emission, higher requirements are put forward for the performance of diesel engine fuel injection systems. Cavitation flow in diesel fuel injectors is an extremely important factor affecting spray characteristics. In this study, the occurrence of cavitation in the fuel injector nozzle and its impact on mass flow rate and vapor fraction at the outlet of the fuel injection hole are studied numerically for various fuels such as diesel, gasoline, ethanol and methanol. The results show that the mass flow rate of diesel is the highest and that of gasoline is the lowest. Methanol and gasoline have the highest vapor content, followed by ethanol, and then diesel with the lowest vapor phase. For mass flow, the mass flow is inversely proportional to the viscosity of the fuel, and for cavitation, the amount cavitation is inversely related to the viscosity of the fuel. This agrees with many researchers’ findings.

In order to study the injection property of diesel engine fuel injector, the three-dimension combustion model of TBD620 diesel engine is constructed on the AVL Fire software platform. A numerical simulation of the two injectors’ fuel injection process at different load conditions has been done. The influence on fuel and air mixing process is analyzed. The results show that the special injector has a good performance at low load, but the standard injector is more favorable for fuel and air fully mixing at high load.

For proper combustion, bowl in the piston geometry plays a crutial role when the engine valves are in closed position. In the present work, the combustion geometry is of hemi-spherical groove in the upper region of the piston.simulations weres conducted for different blends( b20+al40, b20+al80) to analyze the combustion features in a four stroke diesel engine using ansys r18.1 software considering above geometry of the piston. . Pertaining to greater amount of density, viscosity of biodiesel blends, variations for b20+al80 render more performance than the biodiesel. Turbulent kinetic energy of both the fuels follow similar trend due to proper mixing of air with the fuel from fuel injector.
