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.

Abstract: PURPOSE: A direct injection engine with an injector is provided to improve noise and vibration absorbing performance by employing a ring-shaped metal washer formed with damping rubber. CONSTITUTION: A direct injection engine comprises a cylinder head, an injector(140), and a washer unit(120). The cylinder head has a mounting hole and a raised protrusion for reducing the width of the mounting hole. The injector directly sprays fuel into a cylinder through the mounting hole and has a housing inclined surface corresponding to the raised protrusion. The washer unit is interposed in between the housing inclined surface and the raised protrusion to absorb and reduce the vibration generated between the injector and the cylinder head. The washer unit comprises a ring-shaped metal washer(200) whose bottom surface contacts the raised protrusion and damping rubber(210) which is elastically deformed and compressed when the housing inclined surface is moved toward the metal washer.

Abstract: PURPOSE: An oil temperature modeling method is provided to model an oil temperature precisely without an oil temperature sensor by using the starting coolant temperature and the integral value of MAF(Mass Air Flow). CONSTITUTION: An oil temperature modeling method comprises steps of calculating an oil temperature change possibility which represents a changeable range of oil temperature(S210), obtaining a working oil temperature change possibility from the oil temperature change possibility in consideration of vehicle operation(S220), and calculating the final oil temperature model by adding the working oil temperature change possibility to the existing oil temperature model(S230). The oil temperature change possibility is calculated by subtracting the existing oil temperature model from the value that an oil temperature gradient and an oil temperature offset value are added to an oil temperature raw value.
