摘要： A fuel injector for internal combustion engines is provided, which has a valve seat member, bordering a valve chamber, having a valve seat and spray orifices and a central blind-end bore as well as a valve member that is able to be driven to cause a lift motion having a closing head, which, together with a valve seat, forms a sealing seat lying upstream of the spray orifices. In order to prevent an underpressure developing in the blind-end bore in the closing phase of the sealing seat, and a partial return flow of the fuel connected with it, the closing head of the valve member is provided, at its end face facing towards the valve seat member, with a plunger sticking out from closing head, which has a shape adjusted to the contour of the blind-end bore, and dips into the blind-end bore when the sealing seat is closed.

摘要： Systems and methods are provided for an engine. The system comprises a direct injection engine having a cylinder in which a piston is slidingly supported to form in combination with a cylinder head a combustion chamber; a fuel injector for the cylinder having a catalytic coated tip portion that projects into the combustion chamber; and an electronic controller to control the operation of the engine and operates the engine in a heating mode of operation if heating of the fuel injector tip is requested. Various methods for heating the fuel injector tip are proposed including operating the engine on a reduced number of cylinders and varying one or both of fuel injection timing and quantity of fuel injected and the ignition timing in order to increase the temperature of combustion.

摘要： An anti-fouling device for an internal combustion engine aftertreatment injector includes a member mountable as an interface between an exhaust conduit and the aftertreatment injector. The member has an inlet to receive air from an air source, and is formed with a passageway to guide the received air to at least one outlet to direct the air to a nozzle of the injector. The air flow surrounds the nozzle to prevent or inhibit exhaust gas from the exhaust conduit from contacting the nozzle.

摘要： An injection control unit of a fuel is provided, which prevents generation of a nozzle deposit of a fuel injector. In a control unit of a fuel injector capable of controlling a lift height that is a distance between a valve body and a valve seat, after start of fuel injection and before end of the fuel injection, after the lift height is controlled to a first height, a period in which the lift height is controlled to a second height which is lower than the first height is provided for a predetermined period. According to such a configuration, when the lift height of the valve body is lowered to the second height after the fuel is injected at the first height, a fuel velocity in the vicinity of an inner wall of an injection port is increased due to an inertial force of the fuel and reduction in an opening area. By a fuel flow at a high velocity, a contamination substance adhering to a wall surface is washed away.
