Evaluation of Diesel Engine Performance Using Biodiesel from Cooking Oil Waste (WCO)

Abstract

The increasing use of fossil fuels will cause the world's oil reserves to be depleted. In this case, it is necessary to increase the use of alternative renewable fuels, one of which is biodiesel waste cooking oil (WCO). The method used is an experimental test with a mixture of used cooking oil biodiesel and fuel. Before testing, the temperature of each fuel is increased to determine the effect of temperature on the density and viscosity values. The highest density value is found in B50 fuel at 26 °C, with a density of 0.854 gr/ml, while the lowest density is found in diesel fuel at 60 °C, with a density of 0.822 gr/ml. The highest viscosity value is found in B50 fuel at 26 °C and 60 °C, which is 3.26 cSt. After that, testing was carried out on a diesel engine, which produced the highest thermal efficiency value of 21.16% on B50 fuel with a temperature of 60 °C at 1000 rpm rotation and a load of 4000 watts. The lowest thermal efficiency of 6.43% was found in B50 fuel with a temperature of 26 °C at 800 rpm and a load of 1000 watts. The lowest consumption was found in B30 with a temperature of 60 °C at 1200 rpm, which was 420.78 gr/kWh. From the results of the tests that have been carried out, it can be concluded that the lower the density and viscosity of the fuel, the better the performance of the diesel engine on average. High temperatures effectively make the engine performance value better than normal temperatures (26 °C), and the performance of diesel engines is better with WCO fuel, especially in SFC.

Design of Motorcycle-Passenger Ship (Klotok) Catamaran Type for Kampung Baru Balikpapan - Penajam Paser Utara

“…There is a difference in resistance between a mono-hull and a catamaran, where the catamaran has a lower level of resistance than a mono-hull [21] [22]. In determining engine power, care must be taken so that it is not too large because large power has a large fuel consumption value as well [23] [24].…”

Perencanaan Distribusi Penerangan Kapal Ikan Multipurpose 70 GT Menggunakan Metode Zonal Cavity

“…Dalam penentuan mesin utama dan generator harus benar-benar akurat karena hal ini terkait dengan biaya operasional kapal khususnya konsumsi bahan bakar. Semakin besar daya dan torsi suatu mesin maka akan berdampak pada konsumsi bahan bakar juka akan semakin besar [4][5] [6], sehingga perlu dilakukan perencanaan yang matang seperti perencanaan distribusi penerangan yang hemat energi agar mesin (generator) yang digunakan tidak terlalu boros [7] [8]. Dalam merencanakan instalasi dan distribusi penerangan di atas kapal harus mengikuti standar dari regulasi yang mengatur tentang intensitas tingkat pencahayaan ruangan di atas kapal.…”

Freeboard and Trim Measurement: a Case Study of Landing Craft Tank Conversion to Ship Power Plan

“…When redesigning, several main factors must be considered, such as the value of resistance and ship stability after changing the design must be better than the previous design [1]. With a high resistance value, it will affect the amount of engine power used [2]- [4] , besides that it will also greatly affect the value of fuel consumption because the amount of power is directly proportional to the rate of fuel consumption [5]. Several cases of ship redesign or commonly called ship conversion have also been carried out in related research studies.…”
