摘要： A fuel injection system in the present invention is provided with a fuel injection valve (10) which incorporates a heater (20) for heating fuel before being injected. The temperature of the heater (20) is estimated on the basis of the resistance value RHtr of the heater (20). The temperature of the heater (20) estimated at or after the time of occurrence of a point of inflection in the resistance value RHtr of the heater (20) is corrected in order to reduce to zero the difference between the nucleate boiling start point temperature and the estimated temperature value of the heater (20) at the time of occurrence of the point of inflection.

摘要： A control apparatus for an internal combustion engine, wherein the internal combustion engine includes a fuel injection valve injecting fuel directly into a cylinder. The control apparatus includes an ECU. The ECU is configured to execute a divided injection control to inject fuel from the fuel injection valve by a plurality of partial lift injections. The ECU is configured to execute a division number reduction control when the value of a spray shape parameter representing spray shape fluctuation is greater than a division number reduction determination value. The division number reduction control is control to reduce the number of partial lift injections in one engine cycle and to lengthen an injection time of each of the partial lift injections.

摘要： A fuel injection valve having a variable stroke mechanism is constructed. A valve body provided to be slidable; a first movable element for cooperating with the valve body; an inner fixed iron core provided at a position to oppose a second movable element; an outer fixed iron core; and a coil are included. A lift amount of the second movable element is set larger than a lift amount of the first movable element, and a portion of the second movable element is projected into the first movable element. In this way, large and small lifts are constituted by using a difference between magnetic attractive forces that are generated in the first movable element and the second movable element by a current supplied to the coil.

摘要： A fuel injector is disclosed herein. The fuel injector includes an injection line, a control valve, a check rod, a control cavity, a high pressure inlet, and a drain line. The injection line fluidly connects a fuel inlet to an injection cavity. The control cavity is adjacent an upper end of the check rod distal to the injection cavity. The high pressure inlet fluidly connects the injection line to the control cavity. The control valve blocks the flow of fuel from the control cavity to the drain line when the control valve is in a closed position and does not block the flow of fuel from the control cavity to the drain line when the control valve is in an open position.

摘要： A fuel injector includes an injector body that defines a fuel inlet, a drain outlet and a nozzle outlet, and has disposed therein a nozzle chamber, a needle control chamber and a valve chamber. The needle control chamber is fluidly connected to the drain outlet through a drain passage that includes the conical seat, is fluidly connected to the nozzle chamber through a Z orifice, and fluidly connected to the valve chamber through an A orifice. The nozzle chamber is fluidly connected to the valve chamber by a pressure passage that includes an F orifice that opens through a flat seat. A control valve member is trapped to move between contact with conical seat and contact with the flat seat. An electrical actuator is operable to push the control valve member away from the conical seat toward the flat seat when energized. A direct control needle valve has an opening hydraulic surface positioned in the nozzle chamber and a closing hydraulic surface positioned in the needle control chamber. The fuel injector may include first and second electronically controlled valves for independently injecting a gaseous fuel and a liquid fuel.

摘要： A fuel injection valve injects a fuel into the combustion chamber or into the injection port of an internal combustion engine, the valve being actuated by an actuator assembly that includes a small displacement actuator and a large displacement actuator. The method includes commanding the small displacement actuator to move the valve member to a first open position corresponding to a first flow area and commanding the large displacement actuator to move the valve member to a second open position corresponding to a second flow area that is larger than the first flow area such that the ratio between the second flow area and the first flow area is at least 15:1. The fuel injection valve can also be operated to alternatively inject two different fuels, one of the fuels being a gaseous fuel and the other one being a liquid fuel.

摘要： A method to control an injection pressure level of fuel within a unit injector is provided. The method includes provision of a second spill valve in the unit injector, which is connected in parallel to a first spill valve. The fuel is delivered to the unit injector with the first spill valve maintained in a passive state. This facilitates return of the first portion of the fuel to the low-pressure fuel manifold. The first spill valve is actuated to an active state to block the flow of fuel to the low-pressure fuel manifold, to maintain the unit injector at the injection pressure level. The second spill valve is actuated concurrently or prior to the actuation of the first spill valve. This facilitates return of a second portion of the fuel to the low-pressure fuel manifold. This is done to limit the injection pressure level within the unit injector.
