Emissions and fuel consumption characteristics of a heavy duty diesel engine fueled with Hydroprocessed Renewable Diesel and Biodiesel

摘要: Renewable biofuels such as Hydroprocessed Diesel (HRD) and Biodiesel (B100) are perceived potential alternative fuels for compression ignition (CI) engine. HRD B100 produced from the same feedstock i.e. Jatrophacurcas oil by transesterification hydro-deoxygenation reactions respectively. Petro-diesel served a reference fuel. The main objective of this study is to identify better fuel among in terms emissions consumption characteristics. C–H–O based lubricity additive was added give adequate injection pump. Both showed substantial reduction particulate matter (PM), carbon monoxide (CO) hydrocarbon (HC) compared petro-diesel. But NOx increased 26% 77% case fueled Brake specific (BSFC) engine with lower than A comparative analysis emission results revealed that performed well on many counts PM, CO HC, but outperformed BSFC, which vital parameters CI engines. Hence, may be considered promising engines over other transesterified biodiesels.
