Recirculated gas and water injection device for intake circuit of internal combustion engine, has water duct extending into recirculated gas duct, and water distributor part with tapered-shaped end located inside recirculated gas duct

摘要

The device has a water injection system (9) with a water distributor part and water ducts, where each water duct extends into a recirculated gas duct (11). A tapered-shaped end of the water distributor part is located inside a recirculated gas intake (10). The recirculated gas intake and the recirculated gas duct are defined in a cylindrical head (3) of an internal combustion engine (1), where the recirculated gas duct emerges from an intake manifold formed in the cylindrical head.
