Effects of Intake Components on Combustion and Emission Characteristics in an n-Butanol/Diesel Blend Fueled Engine

Abstract: To assess the effects of intake components and n-butanol application on compression-ignition engines, an experiment was carried out based on a singlecylinder engine fueled with n-butanol/diesel-blended fuel. The results show that with the increased n-butanol fraction of the blended fuel, the emissions of particulate mass (PM) decrease significantly, but the NO x and hydrocarbon (HC) emissions deteriorate. For B15 and B30, the PM emissions are 66.2% and 74.4% lower than B0, respectively. Furthermore, exhaust ga… Show more

“…Exhaust gas recirculation (EGR) is an effective technology used to reduce NO x emissions from diesel engines. However, a too high EGR rate will cause some changes in the combustion process, including the lower IOC, longer ignition delay, lower heat release rate, and decreased combustion completeness, which lead to a series of problems, such as the deterioration of HC, CO, and particulate emissions and the decline of engine power and fuel economy . In order to cope with these problems arising from high EGR, some researchers have adopted the method of intake supercharging to increase the IOC and optimize the engine emissions and fuel economy comprehensively through the coordinated control of EGR and supercharging technology. , However, limited by the mechanical strength, the compression ratio of intake supercharging cannot be too high, and this means will consume exhaust energy.…”
