Abstract
The use of biodiesel fuel still has problems. One of the problems is that it is not easy to ignite this, which causes incomplete combustion, which causes the performance of the diesel engine to be less than optimal. This study aims to solve the problem of biodiesel properties affecting the performance of diesel engines. To overcome this problem, ozone is dissolved in diesel fuel because the oxidizing ability of ozone contains more chemical potential energy than oxygen, it can result in significantly greater product pressure and heat during combustion. In this study, ozone dissolution can be carried out using an ozone generator which is a simple, and environmentally friendly technology, ozone dissolution into 30% biodiesel fuel was carried out with variations in ozone dissolution, namely 140×10−6 g/s, 278×10−6 g/s, 556×10−6 g/s. The performance measurements produced by the engine were analyzed using the Diesel TV-1 engine with a compression ratio of 1:18 and at 1 kg, 3 kg, 5 kg, 7 kg, and 9 kg loadings. The results showed that dissolving ozone in the fuel increased the torque produced by the engine at a load of 9 kg B30% by 16.45 Nm, B30% higher with ozone dissolving 556×10−6 g/s by 16.81 Nm, increasing the effective power at a load of 9 kg B30% by 2.49 kW higher B30% by dissolving ozone 556×10−6 g/s by 2.56 kW, reducing specific fuel consumption at a load of 9 kg B30% by 0.33 kg/kW.h lower B30 % with ozone dissolving 278×10−6 g/s of 0.30 kg/kW.h, increase the volumetric efficiency of 9 kg load B30% by 0.066% higher than B30% by dissolving ozone 556×10−6 g/s by 0.070%. Dissolving ozone in biodiesel fuel can increase engine torque by 2.18%, increase effective power by 2.8%, reduce specific fuel consumption by 13.33% and increase volumetric efficiency by 14.04%.
