Fuel injection system for internal combustion engine e.g. diesel engine, has agglomerate presenting interstices whose one layer allows passage of elongated and fine impurities that are blocked by subsequent layer of agglomerate

摘要

The system has agglomerate presenting interstices (1), where the interstices has a layer which allows the passage of elongated and fine impurities (3). The impurities are blocked by a subsequent layer of the agglomerate, where the agglomerate is inserted in a high pressure system.
