Abstract

In order to reduce the global environmental impact from internal combustion engines in terms of emissions particularly in the production of greenhouse gases (GHG), one of the most promising ways is the use of bio-derived fuels. To this purpose, the utilisation of biodiesel (pure or in blends) in diesel engines is already quite common in some countries due to its properties comprehensively similar to petro-diesel. The major positive effect not only intrinsic to the significant reduction in CO2 emission but reducing CO, HC and smoke emissions, even though it typically causes an appreciable increase in NOx emissions. However, the use of the biodiesel has some limitation due to efficiency drops and long term complications to the engine. Therefore, this study aims on examine the effects of different biodiesel blends on engine performance and exhaust gas emissions of marine auxiliary diesel engine and recommends bio-fuel that optimising the engine performance and lower emissions. This study found there has been an increment in engine performance specifically on torque, brake power, brake thermal efficiency (BTE) and brake mean effective pressure (BMEP) along with lower and better in brake specific fuel consumption (BSFC) crude palm biodiesel oil (CPO) and jatropha cursas biodiesel oil (JCO) blended fuels, while decreased in engine performance associated with higher BSFC by waste cooking biodiesel oil (WCO) blends compared to neat petroleum diesel. Aside, the reductions of CO, CO2 and HC by CPO; slightly increment in CO2, NOx and HC by JCO and acceptable CO2, CO and NOx gas productions by WCO has been discovered. Conclusion can be made is biodiesel blend fuels is operable in diesel engines without engine alterations as well as advantageous for exhaust emission reductions yet beneficial to the environmental sustainability.
