ELECTRONICALLY CONTROLLED GOVERNOR OF ELECTRONICALLY CONTROLLED FUEL INJECTION SYSTEM

摘要

PURPOSE: An electronic governor of a fuel injection device is provided to efficiently control fuel injection level by using a plunger type solenoid. CONSTITUTION: A shaft(8) is inserted into a bearing(12) in a governor housing(2). A mobile plate(14) is mounted at an upper portion of the shaft, and a CSP(Control Sleeve Position) sensor(3) is installed near the mobile plate. A control sleeve(10) sliding along a plunger(11) is connected to the lower end of the shaft via an eccentric ball pin(9). A bobbin(17) whereon a coil(16) is wound below the CSP sensor. An adjusting core(18), a return spring(19) and a rack(20) are inserted into a center hole(15) of the bobbin. A pinion(21) is formed on the circumference of the shaft to be engaged with the rack. Fuel injection is controlled by controlling position of the plunger through the control sleeve moving by rotation of the eccentric ball pin. According to rotation of the shaft via a plunger type solenoid instead of a yoke, fuel injection control is improved.
