Small scale power generation using a dual fuel system

Yusaf, Talal and Al-Atabi, Mushtak Talib Ali and Buttsworth, David R. (2003) Small scale power generation using a dual fuel system. RERIC International Energy Journal, 4 (2). pp. 129-138. ISSN 0857-6173


Single-cylinder diesel engines are widely utilized in Malaysia to generate electricity on smallscales in open markets and rural areas. This paper presents a brief study carried out to:(i) understand the nature of exhaust emissions (NOx , CO and CO2 ) when adopting a dual fuel system using Compressed Natural Gas (CNG) in a single-cylinder, stationary diesel engine, and (ii) compare the dual fuel emission and engine performance results to those of diesel. The use of CNG is considered a possible solution for reducing the toxic emissions from these engines. This work shows that by using the dual fuel system, NOx , CO and CO2 concentrations in the exhaust gases were, on average, reduced by 54%, 59% and 31%, respectively when the engine runs at maximum-load operating conditions. The average power output from the engine operating on dual fuel was 10% higher than that operating on diesel over the tested range of engine speeds
