Performance and emission characteristics of a single cylinder four stroke cycle direct injection diesel engine using biodiesel-diesel blends as fuel

This paper describes the performance and emission characteristics with biodiesel diesel blends on a single cylinder four stroke cycle direct injection diesel engine. Use of biodiesel diesel blends can conserve diesel. Biodiesel is renewable source of energy and will save foreign exchange in importing the diesel in crores of Indian rupees. The engine was mounted on test bed and fitted with all attachments like hydraulic dynamometer, fuel consumption and air consumption measuring systems. Exhaust gas analyzer was used for measuring emissions. The engine was run in the neat diesel mode and data was collected for power, speed, air and fuel consumption.Exhaust emissions were also measured. The experiments were repeated for 20%, 40%, 60%, 80% and 100% biodiesel substitution. The biodiesel was prepared from karanja oil. It was seen that the power output was improved with biodiesel substitution. There was also reduction in the BSFC and opacity with increased biodiesel substitution in diesel.
