Influence of blend fuels on combustion characteristics for small diesel engine 2007-32-0023

In practical diesel engines it is necessary to achieve a low emission and low fuel consumption with high load operation. Several techniques were developed for reducing the emissions and fuel consumption from diesel engines, such as EGR (Exhaust gas recirculation) and blend fuels. Nevertheless, there are only very few data available for reducing the emissions and fuel consumption in small diesel engines (100-250cc) by using blend fuels. As the first step of this study, experiments have been carried out to examine the influence of blend fuels on combustion characteristics in small diesel engine. The main conclusions are as follows: 1) The maximum burning pressure for water emulsion oil is smaller than that of light oil. 2) NOx emission of light fuel with coconut oil is higher than that of light oil. 3) It is possible to improve the combustion behavior by using blend fuel for small diesel engines.
