PENGARUH PENGGUNAAN CATALYTIC CONVERTER BERBAHAN ARANG KAYU ALABAN DENGAN ADITIF TEMBAGA (Cu) TERHADAP EMISI GAS BUANG DAN KONSUMSI BAHAN BAKAR PADA TOYOTA KIJANG 5K

Abstract

This study aims to determine the results of exhaust emissions and fuel consumption in the use of alaban wood charcoal with copper additives with variations in hole diameter, mixture and rpm. The data of this study were obtained from the results of testing using gas analysis in the Environment Agency and fuel consumption test, independent variable data used a mixture of 82.5% alaban wood charcoal, 7.5% copper additives, 10% PVA and 87.5% alaban wood charcoal, 2.5% copper additive, 10% PVA, dimensions of hole diameter 15 mm and 20 mm, idle RPM, 1500, 2500, 3500. The dependent variable is a 5K Toyota Kijang car. The control variables used were exhaust gas emissions testing namely CO2, CO, HC and O2 and fuel consumption tests. From these results the largest increase in CO2 was 67.46% in the composition of B rpm 2500, the largest decrease in CO 75.69% in the composition B rpm 3500, experienced the largest decrease in HC 81.67% in composition B and stationary conditions, decreased O2 the biggest is 40.7% in composition B rpm 2500. From the test results, the fuel consumption has the largest decrease of 13.33% in the hole diameter Composition B 15 mm rpm 1500.
