“…This phenomenon shows that the effect of fixed fin addition on air intake valve can improve engine power performance at 2200 rpm up to 10% in full load condition. Now in Figure 7 shows how the addition of fixed fin on air intake valve affected torque in maximum load [25][26]. Figure 7 shows that on 1800 rpm, maximum torques when using air intake valve and air intake valve with the addition of fixed fin are 14.1 Nm and 14.5 Nm, respectively.…”

“…Having discovered the highest power at maximum load then it can be further analyzed how about the highest power and the highest torque relation with the specific energy consumption needed to produce the best power and the best torque. Figure 8 shows the power produced by the engine on each variation of fuel (diesel engine and gas-oil fuel engine) in constant rpm and full load condition [25][26][27][28][29][30]. Based on Figure 8 it can be explained that the difference is quite high when the engine operates at a constant rpm at 2100 rpm and 2200 rpm for maximum load condition.…”

“…This is due to a decrease in the initial injection and the injection duration to the engine combustion chamber. The condition of the dual-fuel engine with the fin adding on intake valve-based simulation has been increased the turbulent flow in the combustion chamber of the engine [25][26][27][28]. The objective of this paper is to investigate the effect of fin adding on the intake valve of dual fuel (gas-oil) engine on the performance based on the experiment.…”

The modification of diesel engine into the dual-fuel engine or specifically gas-oil fuel engine has been done to solve the problem of the depletion fossil fuel oil reserves in the world. Fossil fuel oil reserves are projected to be exhausted in the next 50 years or less by prediction. The working system of the gas-oil fuel engine was injecting (gas fuel) to combustion chamber along with the air during the suction step in the intake manifold and burned with the diesel as the lighter. The gas fuel was used here is CNG (Compressed Natural Gas). But the performance of the engine when using the addition of gas fuel has decreased. The modification, like the addition of fixed fin in the air intake valve, is done to increase the swirl ratio. So, that turbulent flow of air comes in along with the gas fuel to be better. As a result, the combustion process in the combustion chamber got better. By applying a fixed fin addition into the air intake valve gas-oil fuel engine, it can increase engine performance better. The power generated by the engine with fin adding increases at maximum load. While torque of engine with fin adding increased in maximum load condition. For specific energy consumption (SEC) has been decreased impact of the fin, adding on the air intake valve.

“…In recent years, the use of LNG has grown with the application of dual fuel engines to various types of ships [14]. Since its first discovery by Wärtsilä in 1995, the dual-fuel engine is now seen as a reliable technology for use on various ships, such as use on harbor tugs [15]. The use of LNG as a fuel can reduce NOx, SOx, and also CO2 significantly [16].…”

“…LNG as a whole has almost no drawbacks, but LNG is non-renewable compared to hydrogen. The use of LNG as fuel in tugboats utilizes a fuel transfer system with pressure build up [15][16][17]. Ship must comply with MARPOL Annex VI especially harbor tug because there are people live near the port.…”

Implementation of the dual-fuel engine as ship main propulsion in Indonesia is low. There is a need for a study about the ship design process for dual fuel engine ship, especially for the engine room. Process and instrumentation diagram can’t give a whole picture of the real engine room, but three-dimensional can provide this. First, this study is to know about the process and instrumentation diagram on harbour tug diesel-LNG dual fuel engine 2 × 2500 HP. Second, this study is to know about the original, clustered, and reordered design structure matrix of all piping components. Third, this study is to know about three-dimensional design using modularization with rule-based algorithm. Components from the bilge & ballast system, oily water separator system, firefighting system, domestic supply and discharge system, marine diesel fuel oil system, LNG fuel oil system, lubricating oil system, cooling system, and compressed air system are inserted in original DSM. The rule-based algorithm is for clustering and reordering. At the end of the original, clustered, and reordered DSM there is a need for the objective function and sum value calculation. In this study, DSM modeler is used to do the clustering and reordering process included in one by clicked clustering algorithm feature. So, in this study is decided that reordering process is done manually using the workflow of the system to ensure that clustering algorithm feature can give clustered and reordered DSM, by compared the objective function and sum value from the original, clustered, and reordered DSM. The result of the objective function and sum value comparison always give less value than the original and clustered DSM. Clustered and reordered DSM had the same value. Sometimes the objective function and sum value of reordered DSM is greater than clustered DSM, which means there is human error when manually reordering the clustered DSM. Less value of the objective function and sum value DSM is used to create three-dimensional. Components that are included in one cluster need to be located nearly. Modularization with rule-based algorithm is applicable in three-dimensional design engine room layout.
