摘要： There is provided a fuel injection valve in which nozzle holes are formed on a metering plate and fuel flowing on a face of the metering plate on the upstream side is injected outside of a face of the metering plate on the downstream side through the nozzle holes. The fuel injection valve includes a vortex flow generator means for changing a flow of fuel passing in each nozzle hole into a vortex flow, wherein the vortex flow generator means is provided on the upstream side of the metering plate. The vortex flow means is a vortex flow generator groove provided on an upper face of the metering plate and connected with a wall face of an entrance of the nozzle hole, and a main stream of fuel flowing in the groove is directed to a position shifted from the center of the nozzle hole. Alternatively, the vortex flow means is a protrusion formed on an upper face of the metering plate. A flow of fuel is changed into a vortex flow in the nozzle hole and injected from the nozzle hole. Therefore, fuel can be excellently atomized and diffused as a megaphone-shape without being formed into a liquid column spray.

摘要： A nozzle holder includes a support portion, which supports a downstream end surface of a planar wall of an injection hole plate. The injection hole plate provided with injection holes is welded to one of the valve body and the nozzle holder. The planar wall may be curved and may be thus convex in an upstream direction toward a downstream end opening such that the planar wall is urged against a peripheral edge of the downstream end opening of the valve body. The planar wall may include a reinforcing rib located radially outward of the injection hole.

摘要： In an injection hole plate of a fuel injection device, injection holes are arranged about a circle. Fuel injected from the injection holes forms a flat sector-shaped spray. The intervals between adjacent injection holes are approximately equal to each other, while the diameters of the injection holes are equal to each other. An injection hole is positioned on an imaginary plane, which contains the central axis of the sector-shaped spray along the injection direction and is orthogonal or approximately orthogonal to the sector-shaped spray. The injection holes, away from the imaginary plane in this order, are symmetric with respect to the line of intersection of the injection hole plate and the imaginary plane. The farther each injection hole is away from the imaginary plane, the larger an angle of gradient of the injection hole with respect to the imaginary plane becomes.

摘要： A valve body surrounds a first passage connecting with a cylinder of an engine. A valve member is adapted to be seated on and lifted from the valve seat. An injector body connects with the valve body. The injector body has a pressure control chamber for controlling hydraulic pressure applied to the valve member thereby controlling a lift of the valve member. The injector body has a second passage through which fuel in the pressure control chamber is exhausted. An actuator is adapted to communicating the pressure control chamber with the first passage through the second passage and blocking the pressure control chamber from the first passage. The first passage introduces fuel from the pressure control chamber into the cylinder through the second passage.

摘要： A fuel injection apparatus which prevents delay of the pressurization of the fuel injected and deterioration of the starting characteristic at the time of engine cold starts and the resultant increase in emission of hydrocarbons by leading to an auxiliary startup pump the hydraulic pressure generated in the hydraulic cylinders supporting the driver's seat when the driver gets in the car and sits on the seat before startup, converts this to a high fuel pressure by large and small diameter cylinders, and obtains a fuel spray with a good atomization by a high fuel pressure immediately after startup. Other forces which can be used are the force generated in a hydraulic damper of a suspension by the weight of the driver when getting in the car, the force of opening the driver's side door, the force of stepping on the brake pedal, etc.

摘要： A system for controlling the air-fuel ratio in an internal combustion engine provided with a fuel injector. The system has an O.sub.2 sensor for issuing signals on two levels, one corresponding to a high air-fuel ratio, the other to a low air-fuel ratio, and a feedback control device responsive to the signal from the sensor. The feedback control calculates a correction factor for maintaining the air-fuel ratio to a desired value during steady operation and for indicating the deviation in the ratio from the desired value during transient conditions. This deviation is employed to generate a transient correction value which is selected to minimize the deviation during transient conditions.

摘要： A fuel injection valve 15 is disposed in an intake passage 9 of an engine body 1. A combustion chamber 5 communicates with the intake passage 9 for introducing fuel injected from the fuel injection valve 15 at predetermined intake timings. A plurality of sensors are provided in the engine body 1 or fuel intake system for detecting various engine operational conditions including properties of fuel. A control unit 30 calculates a fuel quantity-of-state in the combustion chamber 5 in accordance with the engine operational conditions detected by the sensors, using an atomized fuel behavioral model representing behavior of fuel injected from the fuel injection valve 15, an intake passage fuel behavioral model representing fuel behavior in the intake passage 9 and a combustion chamber fuel behavioral model representing fuel behavior in the combustion chamber 5. Furthermore, the control unit 30 calculates a fuel injection amount required to adjust an actual gaseous air-fuel ratio in the combustion chamber 5 to a desired value in accordance with the fuel quantity-of-state thus calculated. The control unit 30 uses a cranking model as the combustion chamber fuel behavioral model before an initial explosion is detected and uses a firing model after the initial explosion is detected. The fuel injection valve 15 is opened or closed on the basis of the fuel injection amount thus calculated.
