The Influence of Injection Timing on Emissions Characteristics of a DI Diesel Engine Fuelled with Pistacia Chinensis Bunge Seed Biodiesel

Abstract:

The effect of various fuel injection advance angles on the emissions of an electronically controlled, high pressure, common rail, turbocharged GW4D20 diesel engine fuelled with different pistacia chinensis bunge seed biodiesel/diesel blends has been experimentally investigated. The results indicate that brake specific fuel consumption reduces with the increasing of fuel injection advance angle, and the BSFC of blends is higher than diesel. At 25% load, CO and THC are significantly reduced compared with higher load. The CO emission increases with the increment of fuel injection advance angle. At 75% load, the CO of B10 is lowest, B20 highest. At the same speed, NOx increases with increment of fuel injection advance angle for diesel and biodiesel blends dramatically. However, NOx of blends and diesel are deteriorated at high load, but there are no obvious differences among them.
