In the figure, after a long run, the turn-on delay is not large; however, the turn-off delay increases in proportion to the run duration
And the increased shut-off delay prevents accurate fuel injection, impairing engine performance and increasing noxious gas

Abstract

The present invention proposes a control valve for reducing the variation of injection quantity and an injector having the control valve. The control valve is arranged below the spool and arranged on the solenoid valve. The control valve may include a plurality of slots, so The plurality of slits are formed at an upper portion of the control valve to be in contact with the spool so that the control valve is easily separated from the spool.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2009-0087121 filed on September 15, 2009, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The invention relates to a control valve and an injector with the control valve. More particularly, the present invention relates to a control valve for reducing variation in injection quantity and an injector having the same. Background technique [0004] The development of diesel engines has been studied in terms of emission control. [0005] Therefore, unlike gasoline engines, diesel engines have the use of catalytic devices to reduce NO x and PM (particulate material), so the development of diesel engines focuses on reducing harmful exhaust gases themselves. [0006] The reason why the common rail system (CommonRailSystem) is applied to the diesel engine is to reduce the harmful exhaust gas its...
