TAILIEUCHUNG - Effect of diesel ethanol blends as fuels on performance and emissions of a diesel truck engine
This paper presents an experimental research on performance and emissions of Hyundai D4BB ton diesel engine truck using diesel-ethanol blends with different ratio of ethanol which are ED5 (95% diesel and 5% ethanol by voumel) and ED10 (90% diesel and 10% ethanol by volume) at full load. | Journal of Science & Technology 130 (2018) 060-064 Effect of Diesel-Ethanol Blends as Fuels on Performance and Emissions of a Diesel Truck Engine Nguyen Van Nhinh*, Pham Minh Tuan, Pham Huu Tuyen Hanoi University of Science and Technology, No. 1, Dai Co Viet, Hai Ba Trung, Hanoi, Viet Nam Received: July 17, 2018; Accepted: November 26, 2018 Abstract Recently, the alternative fuels have been widely researched and applied on internal combustion engine in many countries in all over the world because of fossil fuels limit and strict emission regulations. Among biofuels, ethanol is one of the most potential alternative fuels that is normally used for spark ignition engines and also possible for diesel engines. This paper presents an experimental research on performance and emissions of Hyundai D4BB ton diesel engine truck using diesel-ethanol blends with different ratio of ethanol which are ED5 (95% diesel and 5% ethanol by voumel) and ED10 (90% diesel and 10% ethanol by volume) at full load. The results showed that there was a minor change in engine torque and fuel consumption, while HC and CO emissions and smoke reduced quite clearly, but NOx emissions increased a bit when using ethanol-diesel blends as compared to conventional diesel. Keywords: bio-fuel, diesel-ethanol blends, emissions, diesel engine 1. Introduction* blends. Huang et al [6] investigated the engine performance and exhaust emissions of diesel engine when using 10%, 20%, 25% and 30% ethanol blended diesel fuels. In recent years, research and application of renewable fuels for vehicles are now interested in many countries. Among the biofuels, ethanol is a potential alternative fuel because it comes from renewable bio-based resource and it is oxygenated, thereby it is possible to improve the exhaust gas emissions. Ethanol has been used normally as commercial fuel in term of blending with gasoline to replace a part of fossil gasoline for gasoline engines [1,2]. Using blends with low percentage of
