Abstract

Exhaust Gas Recirculation (EGR) is technology to reduce NOX emission of diesel engine. This technology could circulate some exhaust gas into the combustion chamber. The adiabatic combustion temperature could decrease and reduce the reaction of oxygen in nitrogen. This method could inhibit the formation of NOX during the combustion process because NOX formation reactions occur at high temperatures. EGR has some effects such as decreased engine performance, SFOC increases and changes in the combustion process. In order to suppress the negative impact, the research carried out by replacing the EGR valve using a type angle globe valve. Experiments conducted using a single cylinder diesel engine YANMAR type TF85-MHDI. The result obtained in this study is the emission of NOX can be reduced up to 15.6 g/kWh or 44.2% of the engine condition without EGR. The experimental results indicate that the use of angle globe EGR valve can reduce the SFOC up to 35.29 gr/kWh. Results of power, torque and BMEP also better compared EGR standard. While in the combustion process showed that the use of EGR valve angle globe causing peak of combustion pressure becomes lower and the Rate of Heat Release (ROHR) is lowered.
