The alteration of nozzles geometry can cause a difference in fuel mass flow and influence smoke emission.\nInvestigation on the effects of nozzle coking in a diesel injector has been the topic of this paper. The experiments have been carried out in a single cylinder optical engine operating in premixed mode. The head of a Euro 5 production engine has been mounted on an elongated cylinder and the production CR injection system has been used. A sapphire window has been set in the piston head in order to have visible access to phenomena occurring in the combustion chamber. Three injectors with decreasing flow number (FN)\nhave been tested. Engine has been fed with commercial diesel fuel. High spatial and temporal resolution camera has been used for the acquisition of in-cylinder injection and combustion images. It allowed obtaining interesting information about the process evolution in the bowl volume.\nInjectors have shown reduced performance after the coking procedure. Moreover, dependence from the FN has been observed. The alteration of injection parameters and the worsening of air/fuel mixture are the main detectable effects."@en ; prodottidellaricerca:prodottoDi modulo:ID7268 , istituto:CDS058 ; pubblicazioni:autoreCNR unitaDiPersonaleInterno:MATRICOLA10474 , unitaDiPersonaleInterno:MATRICOLA22207 , unitaDiPersonaleInterno:MATRICOLA14903 . ns11:ID317753 pubblicazioni:rivistaDi prodotto:ID261595 .
