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.

摘要： A fuel pump for an internal combustion engine that transmits fuel with pressure by a lifting movement of a plunger that is caused to lift by a movement of a cam includes a lift amount changing mechanism. The lift amount changing mechanism includes a cam in which a height of a projection is varied along an axial direction of the camshaft, and a cam moving actuator that moves the cam along the axial direction of the camshaft. The lift amount of the plunger is changed by moving the cam along the axial direction of the camshaft. An amount of discharged fuel is controlled by changing the amount of discharged fuel per stroke of the plunger and is not determined only based upon the rotation speed of the engine. Therefore, the amount of discharged fuel can be increased with the engine rotated at a low speed, for example when the engine is being initially started, to improve a starting performance.

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 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 fuel injection valve, for an engine, comprising a nozzle body having a plurality of nozzle holes and a needle valve reciprocated in the nozzle body for controlling the inflow of the fuel into the nozzle holes is disclosed. The fuel is rendered to flow into the nozzle holes from a direction along the inner wall surface of the nozzle body around each of the nozzle holes in a first inflow mode, and from a direction substantially perpendicular to the inner wall surface of the nozzle body in a second inflow mode. The first inflow mode and the second inflow mode can be selectively switched to each other. The fuel is rendered to flow into the nozzle holes in the first inflow mode before the lapse of a predetermined time after the engine is started, and in the first or second mode as required after the lapse of the predetermined time.

摘要： An engine, having an intake passage, a throttle valve arranged in the intake passage, and a fuel injector arranged in the intake passage for injecting fuel into the intake passage, comprises an air-flow control valve arranged in the intake passage between the fuel injector and the throttle valve. The air-flow control valve is controlled to close during the engine starting operation, and to open after the engine starting operation completes. The air-flow control valve has a valve element having an axis about which the element is rotatable when the valve is opened or closed. The rotational direction of the valve element is selected so that air flowing through the valve is guided by the valve toward the fuel injector when the air-flow control valve is controlled to an intermediate open position which is between the closed position and the full open position.

摘要： A fuel injection valve for an internal combustion engine includes an injector body and an adapter. The injector body includes a single fuel injection hole and the adapter includes a concave portion defining a dead volume portion and a pillar extending from a bottom surface of the concave portion toward the fuel injection hole formed in the injector body. Fuel injected through the fuel injection hole into the dead volume portion collides with a top surface of the pillar to form a cone-like fuel flow pattern and a large portion of the fuel can directly flow into injected fuel paths formed in the adapted without attaching to and collecting on surfaces of various portions of the adapter. Thus, stable fuel injection from the injected fuel paths can be obtained.
