Effect of the number and position of nozzle holes on in- and near-nozzle dynamic characteristics of diesel injection

•We analyze in- and near-nozzle dynamics of single- and multi-hole diesel injectors.•An X-ray imaging technique was applied for analysis of dynamic characteristics.•Number of nozzle holes significantly changes the transient needle behavior.•Near-nozzle flow characteristics are highly affected by the...
