Effect of Different Biodiesel Blends on Autoignition, Combustion, Performance and Engine-Out Emissions in a Single Cylinder HSDI Diesel Engine 2009-01-0489

The effects of different blends of Soybean Methyl Ester (biodiesel) and ultra low sulfur diesel (ULSD) fuel: B-00 (ULSD), B-20, B-40, B-60, B-80 and B-100 (biodiesel); on autoignition, combustion, performance, and engine out emissions of different species including particulate matter (PM) in the exhaust, were investigated in a single-cylinder, high speed direct injection (HSDI) diesel engine equipped with a common rail injection system. The engine was operated at 1500 rpm under simulated turbocharged conditions at 5 bar IMEP load with varied injection pressures at a medium swirl of 3.77 w ithout EGR. Analysis of test results was done to determine the role of biodiesel percentage in the fuel blend on the basic thermodynamic and combustion processes under fuel injection pressures ranging from 600 bar to 1200 bar. The effects of increasing the biodiesel percentage in the fuel blend on autoignition, rate of heat release, fuel economy and emission of total unburned hydrocarbon (THC), oxides of nitrogen (NOx), carbon monoxide (CO) and particulate matter (PM) are determined.
