Abstract: PURPOSE: A control method of a diesel engine is provided to prevent the sudden raising of an RPM(Revolution Per Minute) by isolating a fuel supply when a control sleeve position sensor is abnormal. CONSTITUTION: The stop of a vehicle and the idle status of an accelerating pedal signal and an idle switch signal are checked during starting an engine(S101-S104). In the idle state, a present RPM is compared with a reference RPM(S105). A present injected fuel amount is compared with a target fuel amount when the present RPM is over the reference RPM(S106). The continuous increase of the RPM is checked over a certain period of time when the present injected fuel amount is over the target fuel amount(S107). A fuel injection is isolated by discriminating as a control sleeve position sensor is abnormal and turning off a governor when each condition is satisfied(S108,S109). Thereby, the sudden raising of the RPM and the sudden starting are prevented.

Abstract: PURPOSE: A noise reducing structure for a high-pressure fuel pump of a GDI(Gasoline Direct Injection) engine is provided to reduce noise by reducing impulsive shock between the other end of a valve needle and the center through hole of a stop disc as fuel remaining at the outer side of an anchor flows through fine holes of a valve disc. CONSTITUTION: A noise reducing structure for a high-pressure fuel pump of a GDI engine comprises a pole core(30), an anchor(40), a washer(60), a compression spring(50), a valve needle(20), and a valve disc(70). The anchor is in contact with or separated from the pole core according to the magnetizing force of the pole core. Fuel flows to the outer side of a needle combining hole through a plurality of fine through-holes. The compression spring pushes the anchor to the opposite side when the magnetizing force of the pole core is released. Both ends of the valve needle are fitted into the needle combining hole and the stop disc and integrally connected to the washer and the anchor. The valve needle moves side by side by the magnetizing force of the pole core and the compression spring. The valve disc reduces impulsive noise from the anchor and the valve needle by controlling the inflow and outflow amount of fuel.
