摘要： 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. Thus, the fuel that is contracted as it passes through the spiral groove can avoid collision with the needle valve, so that a decrease in a flow velocity of the fuel as it swirls through the spiral groove is suppressed.

摘要： A pitch-based carbon fiber sliver providing a high-strength carbon fiber spun yarn is efficiently produced by providing a pitch-based carbon fiber mat comprising a mass of piled-up pitch-based carbon fibers of which fiber extension directions are aligned preferentially in one direction; and directly subjecting the carbon fiber mat to drawing and carding by means of a carding machine while moving the mat in said one preferential alignment direction. The thus-obtained carbon fiber sliver is drawn and twisted to produce a pitch-based carbon fiber spun yarn containing at least 3 wt. % of fibers having a fiber length of at least 150 mm, a number of primary twist of 50-400 turns/m and a tensile strength of at least 0.10 N/tex.

摘要： An internal combustion engine 10 includes a fuel injection valve 37 for injecting a gasoline fuel into a combustion chamber 25, and a spark plug 35. When the internal combustion engine is operated in a light-load region, the fuel is injected at an early and/or middle stage of an intake strode, whereby a homogeneous air/fuel mixture is formed and compressed to thereby perform a premixed-charge compression auto-ignition operation in which the fuel is auto-ignited and combusted. When the internal combustion engine is operated in a middle-load region, a spark-ignition combustion operation is performed. When the internal combustion engine is operated in a high-load region, air taken into the combustion chamber is compressed, and the fuel is injected into the compressed air, thereby performing a diffusion combustion operation in which the fuel is diffusion-combusted.

摘要： An electric control device 70 is applied to an internal combustion engine 10 capable of a pre-mixed charge compression ignition combustion in which air-fuel mixture gas including air and fuel injected from an injector 37 is formed in a combustion chamber 25, and the air-fuel mixture gas is self-ignited to be combusted by compressing the air-fuel mixture gas during a compression stroke. The electric control device injects high pressure fluid such as air from the air injection valve 38 into the air-fuel mixture gas at a predetermined acting timing within a compression stroke prior to fuel pyrolysis starting timing to enhance the temperature un-uniformity of the air-fuel mixture gas. This enables the temperature un-uniformity of the air-fuel mixture gas at the fuel pyrolysis starting timing to become larger than the temperature un-uniformity of the air-fuel mixture gas at the fuel pyrolysis starting timing obtained only by simply compressing the air-fuel mixture gas during the compression stroke. As a result, the combustion is moderated and the combustion noise is reduced.
