Abstract

In this research, an investigation about combustion characteristics of biodiesel dan fossil diesel fuel mixture in stationary direct injection diesel engine is conducted. Method to be used in the investigation is heat release analysis. Heat release analysis is based on data of gas pressure in the diesel combustion chamber, which will be further analyzed to get rate of heat release and total of heat release curve. The curve subsequently will be used to estimate the combustion characteristics, such as ignition delay period, premixed and diffusion combustion, total heat release and mechanism of soot formation from the combustion of biodiesel and fossil diesel fuel mixture. From the research, it is found out that increasing percentage of biodiesel in biodiesel dan fossil diesel fuel mixture tends to reduce/decrease duration of ignition delay, duration of premixed combustion, duration of diffusion combustion, total of heat release …
