  • Patent number: 10508603
    Abstract: An apparatus for controlling an internal combustion engine is provided. An engine includes a compression release mechanism and a fuel injection valve. The compression release mechanism variably controls the opening degree of a valve member, and thereby connects the combustion chamber of the engine with at least one of the intake passage and the exhaust passage in order to release in-cylinder pressure during at least the compression stroke. A controller controls the fuel injection valve to execute coasting with the fuel cut off in which the fuel is cut off under a predetermined condition, and while executing coasting with the fuel cut off, controls the compression release mechanism to increase the opening degree of the valve member of the compression release mechanism as the speed of the engine is higher.

  • Patent number: 9556842
    Abstract: A fuel injection valve includes: a needle valve with a seat surface at a distal end; a nozzle body with a seat section on which the seat surface rests and with an injection opening disposed downstream of the seat section; and a swirl flow generating section with a spiral groove for causing fuel injected via the injection opening to swirl. The seat surface includes a first contact point. The first contact point contacts a second contact point included in the seat section during valve closing. A line segment that is drawn by connecting the first contact point and the second contact point during valve opening intersects a virtual straight line passing a bottom of a first groove section that appears the most downstream side of a cross section of the swirl flow generating portion in a plane including a central axis of the needle valve and a bottom of a second groove section that appears one step upstream side of the first groove portion.

  • Patent number: 9429125
    Abstract: Test liquid (3) including thermosetting resin is injected from an injection valve (2). Light (L) is irradiated to a spray (6) of the test liquid (3) injected from the injection valve (2) as a treatment for producing a hardening effect to the thermosetting resin. Liquid drops in the spray (6) are hardened and collected as particles. Spray characteristics such as a particle size distribution of the injection valve or the like are analyzed by using the collected particles.

  • Patent number: 9194323
    Abstract: A fuel injection device is equipped with a fuel injection valve that is mounted in an engine body and injects fuel containing air bubbles, and void fraction adjustment means that changes a void fraction of the fuel that is to be injected from the fuel injection valve. The void ratio adjustment means increases the fuel pressure of the fuel to be injected from the fuel injection valve when an increase of the void fraction is requested. The void fraction adjustment means adjusts the void fraction of the fuel by changing temperature of the fuel to be injected from the fuel injection valve. By appropriately controlling the void fraction, both fuel atomization and securement of the net amount of fuel can be achieved.
