EXHAUST GAS EMISSIONS ANALYSIS OF DUAL FUEL ON STATIONERY DIESEL ENGINE

The analysis of exhaust gas from diesel engine using dual fuel was examined. The objective of this research is to measure the exhaust gas emissions from single cylinder diesel engine using dual fuel (diesel fuel and biogas). The experimental study was conducted on single cylinder diesel engine with variable of engine speed and volume of biogas intake into combustion chamber. The results show that CO emission were 2.99% volume higher than the conventional fuel. The CO2 emissions were decrease by 9.53% when using dual fuel. The HC emissions of dual fuel were high in the case of high in-cylinder temperature at the high load condition Moreover, the opacity of exhaust emission was decrease by 14.3% at 50 psi load, but slightly increase at 100 psi.
