Abstract

Now the demand for fuel oil has increased, this can cause fuel oil reserves to be depleted. To reduce the use of fuel oil, alternative energy is needed. One alternative energy that can be used to reduce fuel oil consumption is LPG (Liquid Petroleum Gas). The use of alternative fuels for LPG in diesel engines is done by converting diesel engines into dual fuel. This research aims to determine the effect of using dual fuel that are LPG-Diesel fuel on engine performance including power, torque, fuel consumption, emissions, vibration and noise. The research was conducted using a Yanmar TF 85 MH engine at 2000 RPM engine speed with variations in loading of 1000, 1500, 2000, 2500, and 3000 watts, and dual fuel with variations in injector openings of 3ms, 4ms, 5ms. Based on the research results, the use of LPG in dual fuel system with installing ECU (Electronic Control Unit) converter-kit, can replace diesel fuel oil consumption up to 93%. In the use of dual fuel there is an average decrease in power and torque of up to 1.95% if using only diesel fuel have average power up to 2.32 kW and torque up to 11.09 Nm. When using dual fuel there is a decrease in specific fuel oil consumption by up to 44% when using only diesel fuel have average fuel oil consumption up to 414.15 g/kWh. The maximum NOx emission produced is 1.83 g/kWh for a 3ms gas injector opening, 1.48 g/kWh for a 4ms gas injector opening, and 1.81 g/kWh for a 5ms injector opening. The maximum vibration generated is 33.2 m/s² for a 3ms injector opening, 31.4 m/s² for a 4ms injector opening, 27.46 m/s² for a 5ms injector opening, and when used only Diesel Fuel is 32.8 m/s2. The maximum noise generated is 92.33 dBA for 3ms injector opening, 92.43 dBA for 4ms injector aperture, 93.20 dBa for 5ms injector aperture, and 91.73 dBa when using diesel oil only.

Abstract

High ship propulsion performance is the main goal of designers, propeller is one component of the propulsion system that also affects the performance of the propulsion. In propeller planning, it is necessary to pay attention to the efficiency of the propeller, in addition to reducing ship operating costs and reducing CO2 gas emissions which is one of the requirements for ships built above 2013, the rules have been made into the Energy Efficiency Design Index (EEDI) standard. At this time the propeller that is widely used is the B Series propeller including the propeller design used on mini LNG ships, namely the B6.40 propeller, the B Series propeller has a pitch character from the Wageningen Propeller Series study. Innovations are made to get better propeller efficiency by varying the pitch distribution. The B6.40 propeller of the standard constant pitch type was modified to B6.40 variable pitch (high thrust). Propellers with high thrust have better efficiency especially for non-fast boats. This study was conducted to obtain the best propeller efficiency of a constant pitch propeller and three high thrust propeller units using Numeca's Computational Fluid Dynamics (CFD) numerical self-propulsion test. For validation of the simulation program by comparing the results of the open water test B6.40 Wageningen while resistance validation by comparing the ship resistance model test. The results of the self-propulsion test using Disc Actuator show that the propulsion coefficient (PC) of Modified-2 and Modified-3 high thrust propellers is better when compared to constant pitch. The magnitude of the increase in PC value reaches ± 4% higher than the constant pitch type on the Modified-3 propeller.
