ABSTRACT

Global warming, climate change, regulation and limitation on emission has become attractiveness factor that pushing many researchers to build method for reducing emission. As we know that global warming and climate change make a big problem for human life. Dual fuel engine (DF) which has combining two characteristics of fuel between low and high reactivity fuel is represented as one of solution. DF diesel – natural gas consists of diesel oil high reactivity fuel as pilot and natural gas as main fuel, natural gas (NG) has many benefits such as low price, low emission, clean alternative fuel, abundant resources and high thermal efficiency. But in fact, DF concept has weakness factor, methane slip or unburned methane have been criticized as one of greenhouse gases. In many researches find that it has global warming potential higher than carbon dioxide. This paper presents a literature review on the investigation and development technology of methane emission reduction on DF. Some technology and strategy on reducing methane slip are devided into three basic strategy, they are redesign engine, optimization on combustion process and after treatment technology of exhaust gases. Some research opportunities in the field of both technology for reducing unburn methane will be discussed and could be addressed for future research.
