Partially Hydrogenated Waste Cooking Oil as a Fuel in the Diesel Engine

I Ketut Gede Wirawan

Abstract: This research aims to analyse the opacity value of diesel engines from seven types of fuel. The fuels used are diesel (D100), mixture of biner diesel 90-biodiesel of waste cooking oil (WCO) 10 %v/v (B10),mixture of biner diesel 80-biodieselWCO 20 %v/v (B20), mixture of biner diesel 70-biodiesel WCO 30 v/v% (B30), mixture of biner diesel 90-partially hydrogenated biodiesel 10 %v/v (PH10), mixture of biner diesel 80-partially hydrogenated biodiesel 20%v/v (PH20), mixture of biner diesel 70-partially hydrogenated biodiesel 30% v/v (PH30), Then an opacity value test was carried out using a pressure variation of 1900 to 2100 Psi with an increase of 50 Psi for each type of fuel. The research results show that the use mixture of biner diesel-partially hydrogenated biodiesel produces lower exhaust gas emissions compared to diesel and a binary mixture of diesel-biodiesel. Insignificant changes were produced by diesel fuel and diesel-biodiesel binary mixtures above 2000 Psi.
