Abstract
A heated tip fuel injector includes a housing having a bore formed therein for receiving fuel under pressure; a valve seat mounted at one end of the housing, the valve seat including an orifice; a needle valve having one end mounted to an armature and another end which contacts the valve seat to close off fuel outflow from the bore and which is lifted from the valve seat to inject fuel; a heater disposed in the housing upstream of the valve seat and extending around the needle valve; and at least one flow disturbing element disposed upstream of the heater. The flow-disturbing element enhances heat transfer from the heater to the fuel.
