Abstract
An improved fuel injector for an internal combustion engine generating very fine atomization of fuel even at initiation of the valve opening event and including a cylindrical valve element terminating in a semi-spherical end portion which engages a valve seat to close the injector, fuel quantity being controlled by cycling the valve alternately between opened and closed positions at a desired variable rate. Improved fuel atomization is generated by providing an annular space upstream of the valve seat, this annular space being so narrow and short as not to form a significant volume of motionless fuel when the valve is closed which would generate large fuel particles upon initiation of valve opening.
