The new concept of attaching a multi-impingement-wall head (MIW head) located in the center of the combustion chamber, to the cylinder head to obtain a three-dimensional diffusing spray for improving the combustion and performance of a DI diesel engine has been investigated. In this paper, we present the effect of combustion chamber geometry on NICS-MH DI diesel engines. Based on the experimental results of engine performance, it was shown that a reentrant combustion chamber with cutouts and projection has better fuel consumption and less harmful exhaust gases (HC, NO_x and smoke) than other NICS-MH engines. Moreover, compared with a DI diesel engine, the reentrant combustion chamber with cutouts and projection also yields decreased densities of harmful exhaust gases.
