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: 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 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.
