The present study evaluates the impact of combustion chamber design with biodiesel. The combustion chambers used in this work are hemispherical, double wedge, and toroidal. The jackfruit seed methyl ester is used as substitute fuel to diesel fuel. The tests are performed on naturally aspirated, 4-stroke, water cooled, 1-cylinder, direct injection CI engine. The brake thermal efficiency (BTE) is increased for the jackfruit seed methyl ester with toroidal combustion chamber (TJSME) and is about 6.78% compared to diesel. In addition, specific fuel consumption (SFC) of TJSME is decreased upto 13.1% compared to base fuel. Further it is observed that the CO, HC, and CO2 emission are reduced for TJSME. The better performance and emission parameters are recorded for jackfruit seed methyl ester with toroidal piston configuration.

摘要

The present study evaluates the impact of combustion chamber design with biodiesel. The combustion chambers used in this work are hemispherical, double wedge, and toroidal. The jackfruit seed methyl ester is used as substitute fuel to diesel fuel. The tests are performed on naturally aspirated, 4-stroke, water cooled, 1-cylinder, direct injection CI engine. The brake thermal efficiency (BTE) is increased for the jackfruit seed methyl ester with toroidal combustion chamber (TJSME) and is about 6.78% compared to diesel. In addition, specific fuel consumption (SFC) of TJSME is decreased upto 13.1% compared to base fuel. Further it is observed that the CO, HC, and CO2 emission are reduced for TJSME. The better performance and emission parameters are recorded for jackfruit seed methyl ester with toroidal piston configuration.
