Abstract:

Fishing vessels in Indonesia conventionally use diesel engines as their main propulsion engine. However, the use of diesel engines has quite a bad impact on the surrounding environment. So the latest innovations using alternative energy are needed. One of them is the use of electric engines as a replacement for diesel engines in the ship's main propulsion engine. The use of this electric machine will have a friendly impact on the environment. Apart from that, you don't need to spend a lot of money to maintain this electric machine. We can see this by comparing the ship's thrust requirements wi

Diesel engine anti-shock performance is important for navy ships. The calculation method is a fast and economic way compared to underwater explosion trial in this field. Researchers of diesel engine anti-shock performance mainly use the spring damping model to simulate the main bearings of a diesel engine. The elastohydrodynamic lubrication method has been continuously used in the main bearings of diesel engines in normal working conditions. This research aims at using the elastohydrodynamic lubrication method in the main bearings of the diesel engine in external shock conditions. The main bea

Electronic speed governors have become widespread on marine diesel engines. In comparison with hydromechanical ones, they have an additional setting parameter – input signal sensitivity. This parameter allows changing the response of governors to high-frequency disturbances. In camshaft diesel engines, such disturbances are generated when the cams run over fuels pump push rods, while in ME (MAN Energy Solutions) or RT-flex (Wärtsilä) engines they result from the use of inductive sensors with a serrated tape on the diesel shaft for speed measurement.

Abstract:

The object of the study is multicylinder marine diesel installations equipped with electronic speed governors (ESGs) operating under wave disturbance conditions. Modern marine diesel engines used in ship power plants are equipped with ESGs which have the technical capability to adjust the sensitivity of the governor's input signal. This parameter allows modifying the governor’s response to high-frequency disturbances, which is a characteristic feature of diesel engine operation. However, assuming constant engine speed throughout the working cycle overly idealizes the governor’s input signal. T

Abstract:

Energy demand from the community, which continues to increase has resulted in depletion of petroleum (fossil) energy in recent years. Many researchers have sought to find alternative fuels to replace dependence on conventional energy. The mixing of alcohol into diesel fuel has also been carried out by several previous researchers. The main focus of this research is to investigate the combustion performance of diesel engines using a mixture of biodiesel-butanol-water and diesel (B5Bu5W5). This research experiment used a single-cylinder diesel engine with different speeds at 25% and 50% engine l

Hydrogen is considered as a promising gas engine fuel for diesel engines. The problems that occur when converting engines to work on hydrogen are presented. Reliable ignition of hydrogen in the engine is achieved by implementing a two-fuel cycle. In this case, hydrogen ignites from the diesel fuel combustion. Calculations of diesel fuel and hydrogen supply effect on the workflow of a dual-fuel engine of the D-245 type were realized. The main indicators of the engine are calculated when the hydrogen supply changes from 0 to 80%. A criterion characterizing the total toxicity of engine exhaust ga
