Abstract (en)

A damper is formed between the nozzle and the plunger (2) of the fuel injection valve (1). This suppresses the bouncing of the plunger (2) and consequently suppresses secondary injections. Further, this can suppress depositions of chemicals on the fuel injection valve (1), generation of soot at improper combustion of fuel, and combustion control errors. <IMAGE>
