Abstract

The use of Biodiesel as a diesel engine fuel is being prioritized by the government to replace the increasingly thinning fuel oil and to reduce air pollution due to diesel engine exhaust gases. It is expected that in 2050 fuel oil can already be replaced with biodiesel. Biodiesel that has started to be used is biodiesel from palm oil (Elaeis Oliefiera) because the processing plant is already available and is still used as cooking oil. But for local coconuts (Cocos Nucifera) available abundantly not yet utilized maximally. Utilization of local coconut in addition to partial coconut milk is also made as cooking oil and virgin coconut oil (VCO). VCO is processed without the use of heat so that the colour is clear and durable and low viscosity. With good characteristics, VCO can be processed into one of biodiesel for diesel engine fuel. However, because to process VCO into biodiesel requires further processes to use VCO as fuel, mixing between VCO and dexlite is made to improve fuel ignition. The purpose of this study is to use dexlite fuel mixed with VCO as fuel for diesel engines and optimized with preheated heaters to reduce fuel viscosity to improve engine performance. The study was conducted by first measuring the water content in VCO to determine whether the heating process is needed or not to reduce the water content. Then VCO is mixed with dexlite with a percentage of 10%, 20%, 30%, 40% and 50%. This mixture is measured for characteristics which are then used as diesel engine fuel. The performance in question is power, fuel consumption, thermal efficiency, and exhaust emissions. Experimental results from the study show that heating fuel before using a mixture of VCO and dexlite can be compared with pure dexlite with a percentage of 30%, and if it increases to 40 and 50% engine performance begins to decrease and an increase in gas emissions caused by incomplete combustion and high viscosity.
