The Effect of Sodium Hydroxide Absorbent on The Exhaust Emissions From Internal Combustion Engine

Abstract

Exhaust emissions are the residue from burning fuel which can cause air pollution. To overcome this problem, it is necessary to design a system for reducing exhaust emissions of internal combustion engine. This study aims to determine the effect of absorbent concentration on the exhaust emission from internal combustion engine. The research was carried out in 2 stages, namely designing a system for reducing exhaust emissions from internal combustion engines and processing exhaust emissions by channeling exhaust emissions into an exhaust emission reduction system. The internal combustion engine used pertalite. The exhaust emissions consisted of CO, CO2 and HC. The absorbent concentrations were 0.05 M, 0.1 M and 0.15 M. The engine speeds were 800, 1000, 1500 and 2000 rpm. The paired-t test showed that the exhaust emission reduction system in this study can reduce exhaust emission. The one-way Anova test resulted the absorbent concentration affect the exhaust gas emissions, both CO, CO2 and HC which are expressed in the efficiency of reducing exhaust emission.. The greatest efficiency in reducing exhaust emission is CO2 of 67.95%. The lowest efficiency of reducing exhaust emission is CO, which is 46.92%, while the efficiency of reducing HC emission is 62.47%.

Heating Treatment of Incoming Air Combustion Chamber on the E20 Fuel Mixture

“…The increase in hydrocarbons caused by less than perfect combustion can be proven that the highest hydrocarbon value is found at a temperature treatment of 50°C with a hydrocarbon value of 524 ppm, while the lowest value is found in a temperature treatment of 30°C with a hydrocarbon value of 354 ppm, while for a carbon monoxide value the lowest value is found in a temperature treatment of 50°C with a carbon monoxide value of 2.57%. The increase in the value of carbon monoxide is caused by the low temperature in the combustion chamber [14]. with the treatment of air heating can increase the temperature in the combustion chamber so that the value of carbon monoxide becomes low.…”
