The influence of fuel composition on the combustion and emission characteristics of natural gas fueled engines

Kakaee, Amir-Hasan; Paykani, Amin; Ghajar, Mostafa - In: Renewable and Sustainable Energy Reviews 38 (2014) C, pp. 64-78

As global energy demand rises, natural gas (NG) plays an important strategic role in energy supply. Natural gas is the cleanest fossil fuel that has been investigated extensively for use in spark-ignition (SI) and compression-ignition (CI) engines. This paper reviews the research on the effects...

Investigation on combustion performance and emission characteristics of a DI (direct injection) diesel engine fueled with biogas–diesel in dual fuel mode

Barik, Debabrata; Murugan, S. - In: Energy 72 (2014) C, pp. 760-771

In this research work, biogas was produced by the anaerobic digestion of non-edible de-oiled cakes obtained from oil crushing units. Further, the biogas was used as an alternative gaseous fuel in a DI (direct injection) diesel engine, in the dual fuel mode. Diesel was used as an injected fuel...

Feasibility of diesel–biodiesel–ethanol/bioethanol blend as existing CI engine fuel: An assessment of properties, material compatibility, safety and combustion

Shahir, S.A.; Masjuki, H.H.; Kalam, M.A.; Imran, A.; … - In: Renewable and Sustainable Energy Reviews 32 (2014) C, pp. 379-395

The global fossil fuel crisis and emission problems lead to investigations on alternative fuels. In this quest, a successful finding is the partial substitution of diesel with ethanol/bioethanol rather than completely replacing it. These blends of diesel and ethanol/bioethanol can be used in the...
