Performance and emission characteristics with kerosene blending with diesel on a single cylinder four stroke cycle direct injection diesel engine

This paper describes the experimental investigations with kerosene blending with diesel on a single cylinder four stroke cycle direct injection diesel engine. Kerosene is inferior petroleum distillation fraction and is conventionally used in stoves used for cooking. The engine was mounted on test bed and fitted with 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 30% and 50% kerosene-diesel blends. Thermodynamic analysis was done in both cases. It was seen that the power output was improved with kerosene adulteration in diesel. There was also reduction in the brake specific fuel consumption and opacity (exhaust emissions) with increased kerosene substitution in diesel.
