Influence of Combustion Chamber Configurations on the Combustion in Diesel Engine Driven by Emulsified Fuel

Abstract

The authors investigated possible influences of combustion chamber configuration on the engine performances displayed through the use of emulsified fuel. To modify the configuration of the combustion chamber, an adapter is fitted to the entrance of the BIP-type combustion chamber of a direct injection diesel engine. As a result of experiment, it was confirmed that the combustion chamber configuration with lower flow-through velocity at the combustion chamber entrance has a remarkable effect of reducing the NOx concentration and BSFC.
