Effects of the fusel oil usage in HCCI engine on combustion, performance and emission

摘要: Abstract Homogeneous charged compression ignition engines have significant advantages such as high thermal efficiency and low nitrogen oxide particulate matter emissions simultaneously. The interest in alternative fuels is increasing globally to reduce dependence on fossil fuels. Fusel oil obtained a by-product the production of ethyl alcohol. In HCCI engines, it possible control combustion process with octane Up present, no research has been conducted effects fusel oil, which number, engines. this study, combustion, performance exhaust engine at different lambda inlet temperatures were investigated experimentally. operation maps parameters in-cylinder pressure, heat release rate, pressure rise start duration, CA50, ITE examined comparatively. highest was 71.96 Bar use heptane fuel when 2.0 speed 800 rpm. Maximum 45.4% F60 1.8. Under same conditions, heptane, F20 F40 29.1%, 32.7% 34.7% respectively. At 353 K temperature CO emission found be 0.413% 2.5 using fuel. HC 782 ppm by
