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 supplying apparatus has a fuel pump for pumping fuel stored in a fuel tank. The fuel pump supplies fuel from the fuel tank to outside the fuel tank via a take-up portion having a fuel take-up opening that opens in the fuel in the fuel tank and a gas take-up opening that opens in a space formed above the fuel liquid surface in the fuel tank. Fuel vapor formed in the fuel tank can be supplied to outside the fuel tank without being released to the atmosphere, by using a minimal number of component elements.

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 valve seat portion has fuel flow passages arranged between guide portions at predetermined intervals along an outer circumference of a valve body. In addition, a fuel jet adjusting plate has nozzle holes arranged along a circle coaxial with the outer circumference of the valve body, the nozzle holes corresponding to the guide portions. Therefore, even if the valve body rotates circumferentially relative to the valve seat portion, no alteration in the pressure applied to fuel flowing through the nozzle holes occurs. By suitably setting relative locations between the respective nozzle holes and the guide portions and the numbers thereof, the pressure applied to fuel injected from the respective nozzle holes is adjusted, whereby the fuel injected from the respective nozzle holes is optimally atomized.

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： An exhaust gas purification device comprising a three way catalyst, an oxidizing catalyst and a NOx absorbent which are arranged in this order in the exhaust passage. A rich air-fuel mixture is burned in the combustion chamber, and the exhaust gas discharged from the engine is initially introduced into the three way catalyst. Secondary air is fed into the exhaust passage between the three way catalyst and the oxidizing catalyst so that the air-fuel ratio of the exhaust gas flowing into the oxidizing catalyst and the NOx absorbent becomes lean.

摘要： A fuel injection structure for an internal combustion engine includes a straight intake port defining passage formed in an intake passage of the engine and a fuel injection valve disposed within a passage-defining wall which defines the straight intake port defining passage therein. The fuel injection valve is arranged inside the intake passage in parallel with a passage axis of the straight intake port defining passage in an elevational view of the engine. The fuel is injected from the fuel injection valve and flows in parallel with the intake air flow. Due to the parallel flow of the fuel and the intake air, the injected fuel does not tend to adhere to the wall surface of the intake port defining passage. This parallel flow is not affected by a change in the speed of the intake air flow.

摘要： A fuel injection valve includes an injector body having a fuel injection hole and an adapter having a fuel collision surface, two air injection holes and two injected fuel paths. The fuel injected from the fuel injection hole flows in a slug-like pattern and collides with the fuel collision surface where the fuel is atomized a first time. Then, the fuel flows in a direction away from an axis of the adapter in a membrane-like pattern getting thinner in thickness to be finally broken to pieces, that is, to be atomized a second time. The air injected from the air injection holes collides with the membrane-like pattern of fuel to be atomized a third time before the fuel goes out of the injected fuel paths.
