### Effects of nozzle geometry on direct injection diesel ...

In order to make a study in terms of nozzle geometry influence, three 6-hole sac nozzles have been used. Despite Bosch flow number (defined as mass flow injected in 30 s for an injection pressure of 10 MPa and a backpressure of 0.1 MPa) is the same for the three nozzles, they are made with different degrees of conicity, represented by k-factor. ...
