| Summary: | Coconut oil is renewable oil that can be used as diesel fuel. It is one of the answers for recent crisis of energy. The purpose of the research is to compare the effect of coconut oil on diesel engine with diesel fuel. Experiment is done 17 hours for each test fuel based on SAE Paper <br />

942010. The test fuels are 10%-v coconut oil and diesel fuel blends, 100% coconut oil, and diesel fuel as datum. Results show that pure coconut oil gave higher BSFC (28,63%) and lower thermal efficiency (19,88%). Coconut oil-diesel fuel blends gave higher BSFC (13,13%) and lower thermal efficiency (9,86%). <br />
<br />
<br />
Coconut oil gave higher emissions especially in unburned hydrocarbon and smoke. Lower wear materials in fuel system prove coconut oil gave good lubricity. coconut oil gave lower combustion chamber deposit. In coconut oil blends and pure coconut oil experiments, injector choking is occurred. <br />
<br />
<br />
High viscosity and low LHV of coconut oil is the main reason of lower engine performance and worse emissions. Injector choking is caused by polymerization of coconut oil in high temperature. |
