Abstract

Diesel engines are widely used as driving forces in vehicles and industry due to fuel efficiency and high output power. The wide use of diesel engines triggers an increase in fuel consumption and exhaust emissions that are harmful to health. Jatropha is a renewable fuel as a solution to increase fuel consumption. However, the high viscosity and low calorific value result in reduced performance and increased exhaust emissions. Butanol has a high oxygen content and cetane number and low viscosity compared to diesel and jatropha. Addition of butanol is possible to reduce the decrease in performance and exhaust emissions of diesel engines. this study evaluates the effect of butanol on reducing Isuzu 4JB1 diesel engine direct injection emissions. Percentage of blend used 70/30/0, 65/30/5, 60/30/10, and 55/40/15 based on volume. Tests are carried out at 2500 constant turns with a loading of 25% to 100% using the EGR system. The experimental results showed the presence of butanol caused a decrease in soot emissions produced by diesel engines

Highlights

This study evaluates the effect of butanol in reducing Isuzu 4JB1 diesel engine direct injection emissions
Bahan bakar campuran solar dan jatropa dengan kandungan butanol 15% adalah bahan bakar yang menghasilkan penurunan emisi jelaga tertinggi

Summary

Introduction

Luasnya penggunaan mesin diesel menyebabkan peningkatan konsumsi bahan bakar dan emisi gas buang [4]. Penggunaan jatropa masih menghasilkan emisi asap (smoke) yang lebih tinggi dibandingkan solar murni. Menurut Fayad dkk., (2017) [7], bahwa penurunan emisi asap (soot) mesin diesel dipengaruhi viskositas yang rendah dan kadar oksigen yang tinggi dalam alkohol butanol. Kandungan oksigen yang tinggi dalam butanol menghasilkan emisi jelaga yang lebih rendah dibandingkan bahan bakar campuran diesel dan biodiesel.
