Application research of image and signal processing techniques on the bio-diesel engine

By high speed photography, scanning electron microscope and x-ray energy dispersive spectroscopy on the diesel engine fueled with bio-diesel and No.0 diesel, the combustion processing in cylinder and the characteristics of particulate matter (PM) from engine exhaust are researched. The findings show that there are some fine differences between bio-diesel and diesel, such as the transport performance of fuel under high pressure, the ignition flammability of the mixtures of air and fuel, and the granularity characteristics of particle matter from engine exhausts. This research is enormously significant to the development and utilization of bio-diesel.
