摘要： A fuel injection valve is provided that includes a valve seat member (3) having provided therein a conical valve seat (8) and a valve seat hole (7) communicating with the downstream end of the valve seat (8), a flat fuel diffusion chamber (43) radially extending from the valve seat hole (7), the fuel diffusion chamber (43) being formed between the valve seat member (3) and an injector plate (10), and a plurality of fuel injection holes (11) bored in the injector plate (10) so as to open in the fuel diffusion chamber (43), wherein the fuel injection holes (11) are arranged so as to be radially outwardly separated from the valve seat hole (7), and when the height of the fuel diffusion chamber (43) is t1 and the length of the valve seat hole (7) is t2, t2/t1 ≥ 2. It is thereby possible to atomize injected fuel effectively by logically setting the relationship between the length of the valve seat hole and the height of the fuel diffusion chamber, and the relative positional relationship between the valve seat hole and the fuel injection holes.

摘要： The invention relates to an internal combustion engine which injects fuel directly into a cylinder 104 and ignites air-fuel mixture formed in the cylinder, wherein
each fuel injection of said internal combustion engine comprises a lead spray 105 which moves faster and a main spray 106 which moves slower,
the lead spray 105 is oriented towards an ignition plug 114, and
the air-fuel mixture made by pre- and main sprays is ignited twice or more.
This invention of the above configuration can provide a simple and inexpensive direct cylinder injection type internal combustion engine which reduces abrasion of electrodes and consumption of electric power while assuring stable fuel combustions even when ignition timing is retarded.

摘要： According to the invention, the lower part of a longitudinal housing is embodied as a valve seat element (2b) containing a valve seat part (4). Said valve seat part (4) comprises a valve seat (5) provided with injection openings (6), and is embodied as a nozzle body which is separate from the valve seat element (2b) and connected to the same. An injection valve member (9) is guided in the housing in a longitudinally displaceable manner and co-operates with the valve seat (5) in order to close and open the injection openings (6). The outer side of said valve seat part (4) is provided with a seat surface (26) formed by the envelope surface of a circular cone. Said seat surface (26) is used to position the valve seat part (4) on a bearing surface (27) on the valve seat element (2b), also formed by the envelope surface of a circular cone. The half opening angles (28) of the circular cones fixing the seat surface (26) and the bearing surface (27) are selected in such a way that the nozzle bodies (4) are held in the valve seat element (2b) in a self-locking and sealing manner.

摘要： The invention relates to a method for producing a valve seat body (5) of a fuel injection valve (1) comprising swirl channels (36) that are provided inside a recess (35) for generating swirl. To this end, a valve seating (6) of the valve seat body (5) interacts with a valve closing body (4) of the fuel injection valve (1) in order to form a tight seat, and the recess (35) serves as a guide of the valve closing body (4). The inventive method comprises the following steps: manufacturing a blank of the valve seat body (5); providing the recess (35), the valve seating (6) and at least one spray opening (7) inside the blank of the valve seat body (5) and providing the swirl channels (36) inside the recess (35). A non-cutting processing step is used to provide the swirl channels (36) inside the recess (35).

摘要： The invention relates to a method that enables the inclination of the injection direction and the distribution of the penetration force of spray to be adjusted over a wide range, and an axially symmetrical spray shape to be obtained even when the injection hole is inclined, or the shape of the spray to be changed without inclining the injection hole. To provide a fuel passageway 203 as a swirling force adjustment means between the valve seat 201 and injection hole 101 of the fuel injector. This swirling force adjustment means adjusts the distribution of the swirling force of the fuel flowing into injection hole 101, and thus adjusts the spray shape obtained as a result.
