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： In an injection hole plate of a fuel injection apparatus, a second-side hole section of each injection hole extends from a downstream end of a base wall of the injection hole plate and is communicated with first-side hole sections, which extends from an upstream end of the wall of the injection hole plate to an axially intermediate point of the wall. The first-side hole sections may discharge fuel into the second-side hole section in a manner that forms a swirl fuel flow in the second-side hole section. The injection hole plate may includes a collision portion, in which fuel flows supplied from the first-side hole sections collide with one another.

摘要： A fuel injection valve for an engine includes a nozzle located in the vicinity of a cylinder head of the engine. The nozzle has nozzle holes each being opposed to an in-cylinder space defined in a cylinder of the engine. Each nozzle hole has an imaginary injection line that extends from each nozzle hole into the in-cylinder space. The imaginary injection line is directed toward either an upper surface of the piston or the wall surface of the cylinder. The in-cylinder space includes divided spaces each including the nozzle and at least one imaginary injection line. The divided spaces include a piston-side divided space and a head-side divided space. The head-side divided space contains fuel and air mixed at an air fuel ratio that is greater than an air fuel ratio of fuel and air in the piston-side divided space.

摘要： A spark ignition internal combustion engine is equipped with a fuel pressure sensor for detecting a viscosity of fuel supplied to a fuel injector based on a variation in a fuel pressure. In a case of stratified combustion by a spray guided injection, an ECU advances a fuel injection start timing of the fuel injector 4 according to the detected viscosity of the fuel. Thus, even if the viscosity of the fuel is significantly high, the fuel-rich area is well formed at a vicinity of the discharge electrode so that a preferable combustion condition can be maintained.

摘要： An air-fuel ratio control system for a gas-fueled engine which is capable of achieving the combustion in a target air-fuel ratio to surely purify an exhaust gas through an exhaust purification catalyst. In the air-fuel ratio control system, a three-way catalytic converter is placed in an exhaust pipe of the engine and an O2 sensor is located on the upstream side of the three-way catalytic converter. The O2 sensor comprises an element, and an atmosphere side electrode is formed on an inner surface of the element while an exhaust gas side electrode is formed on an outer surface thereof. The exhaust gas side electrode is coated with a catalyst layer which can remove hydrogen through a catalytic reaction. A control unit of the control system controls a fuel supply quantity by a gas injector using a feedback correction coefficient on the basis of the output of the O2 sensor, thereby reducing the deviation between an air-fuel ratio measured by the O2 sensor and a target air-fuel ratio.
