Fuel injector for internal combustion engine, has channel formed in injector body and opened into ejection indent, where channel creates communication between ejection indent and blind indent

摘要

The injector has a channel (25) formed in an injector body (1) and opened into an ejection indent (15). The channel creates a communication between the ejection indent and a blind indent (18) extending a valve seat (9). The ejection indent opens into a combustion chamber of an internal combustion engine. The channel permits to suck in air from the chamber, where the air is mixed with fuel in the ejection indent.
