Abstract

Increased vehicle volume causes a high use of fossil fuels and increased exhaust emissions. Butanol is a renewable fuel that can replace fossil fuels. This is because butanol has better characteristics than gasoline such as high octane value and oxygen content. This results in a more complete combustion process in the combustion chamber so that engine torque and power increase. This study was to observe the effect of using butanol on torque and power in gasoline engines with the EGR system. This test is carried out using a constant engine speed of 2500 rpm. The percentage of butanol in premium fuel is 5%, 10% and 15% of the total fuel volume. The test results show that the addition of 5% butanol to premium fuel can increase torque by 4.88% using a cold EGR system. Engine power experienced the highest increase in the addition of 15% butanol using a cold EGR system of 15.6 kW.

Summary

Introduction

Butanol juga memiliki panas laten penguapan yang tinggi sehingga bahan bakar menguap lebih baik dalam ruang bakar. Hal ini menurunkan konsentrasi oksigen di ruang bakar dan meningkatkan panas spesifik campuran udara masuk yang menghasilkan suhu api lebih rendah sehingga EGR mereduksi NOx. Haiqiao Wei, dkk. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan butanol pada premium terhadap torsi dan daya mesin bensin dengan system EGR. Peningkatan torsi tertinggi terjadi pada variasi bahan bakar P95B5 sebesar 51,9 N.m. Hal ini menunjukan bahwa penambahan butanol 5% pada bahan bakar premium dapat meningkatkan torsi mesin hingga 1,94% dibandingkan premium murni.
