Abstract

Research on biodiesel as an alternative fuel has been widely carried out. Such as mixing one type of oil mixed with diesel fuel with a certain composition. In this research, biodiesel was made by mixing two types of oil and then mixed with diesel fuel with a composition of 30:80, where 30% for mixed oil that is cottonseed oil and coconut oil, then 80% for diesel fuel. And then in this research, the composition between cottonseed oil and coconut oil must be found, so that it will get the best composition between cottonseed oil and coconut oil. For comparison in performance between mixed biodiesel with 4 cSt and 6 cSt, and in the mixing process, using mathematical calculation methods, then the mixing results must meet SNI standards (Standard Nasional Indonesia / Indonesian National Standards). In this research, 4-stroke diesel engines with one cylinder were used. From the experiments and data analysis, biodiesel with 6 cSt more powerful, torsion and BMEP better than mixed biodiesel 4 cSt.

Abstract

The world crisis of fossil fuel availability encourages the development to explore alternative energy which is possible to replace of fossil fuel. The use of biodiesel by using vegetable oil and animal fats is strived to the maximum extent possible, in order to maintain its sustainability. Cotton Seed oil (Ceiba Pentandra) is one alternative that can be used as a substitution fuel. There are four advantages of using Cotton Seed oil as a substitute fuel which are: produce a low level of pollutant, guaranteed availability, can be used for diesel engines with less or no modification and in certain mixes can increase engine lubrication that should increase engine life. The research was conducted through performance test of YANMAR TF85-MH diesel engine using Cotton Seed oil biodiesel with mixture of B30, B20 which has been compared with using diesel oil. From the results of experiment, it showed that the use of Cotton Seed oil has been increase performance than diesel fuel. The addition of biodiesel Cotton Seed oil percentage into the fuel provide greater power but it provides the higher fuel consumption.

Abstract

The world has the same problem to reduce emissions. Based the problem, many technologies invented to reduce the Emission. One of them is EGR (Exhaust Gas Recirculation). EGR is the most simpleNOx reduction by circulating potion of exhaust gas return into the combustion chamber. EGR system is often known by the name the hot EGR where exhaust gas circulation process without cooling system. This new Hot EGR system is designed by the addition of cooling system with air-cooled type. So that the circulating of exhaust gas to be cooled in advance in such that the mass of air increases.This research aims to study the performance and a reduction in NOX of diesel engine with EGR using addition of air cooling system. The experiments were used on diesel engine Yanmar TF 85-MHDI.
