A discharge gap, formed between the center electrode tip and the ground electrode tip, is less than 1.1 mm. And, cross sections of the center electrode tip and the ground electrode tip are equal to or smaller than 0.95 mm2 in a spherical region where a distance from a midpoint of the discharge gap is within 0.6 mm.

    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： 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： An ignition device sets a total discharge period, each discharge period and each intermittent period of a multiple discharge are set by a control map in addition to the setting of a throttle opening, fuel injection timing, fuel injection period and ignition timing for the range of non-stratified charge combustion, when a direct injection-type engine operates in the range of stratified charge combustion. Ignition signals including a plurality of rises and falls are outputted in time with a specific ignition timing after fuel injection. Thus a plurality of sparks are generated from the spark plug, ensuring reliable ignition in response to changes in the concentration of sprayed fuel within the operation range for stratified charge combustion.
