Effect of Model from Candlenut Seed (Aleurites moluccana) to NOx Emission and Combustion Process on Single Cylinder Diesel Engine

Abstract

fossil fuels are non-renewable fuels but are still the main fuel choice, however, it is now becoming increasingly recognized that the availability of fossil fuels are dwindling which further encourages research on renewable fuels. One of the renewable fuels under development and research is biodiesel. The use of vegetable and animal oil is one of the primary choices to decrease the use of non-renewable fuels. Candlenut oil is one of the alternatives under research and development to produce biodiesel as a replacement for non-renewable fuels. In this research is expected to know the NOx emission level and combustion process of single cylinder diesel engine using candlenut oil biodiesel and compared with diesel fuel High-Speed Diesel (HSD). The results of NOx emission comparison between biodiesel candlenut and HSD showed an increase of 0.76 gr/kWh for biodiesel candlenut and 0.51 gr/kWh for HSD fuel. In the burning process test results showed the knocking value of better candlenut biodiesel than HSD which is 5.69 bar for biodiesel candlenut and 6.19 bar for HSD fuel.

The Effect of Mixing Diesel Fuel with Cottonseed Oil and Coconut Oil on The Performance of 4-Stroke Diesel Engine

“…Biodiesel itself has some characteristics that are more advantageous than fossil fuels that are biodegradable, non -toxic, has low CO2 emissions and sulfur gas and is classified as safe to the environment. The use of biodiesel mixed with diesel fuel is obtained with a result of higher viscosity condition [2,3].…”

“…Then there is also a caster oil whose viscosity value is under SNI standards and a cottonseed oil whose heating value does not meet SNI standard. So to know the feasibility of using mixed biodiesel fuel and to get the best mixing formula according to SNI [1][2][3].…”
