摘要:
A direct injected, internal combustion engine combustion chamber configuration and injection control strategy. Stratification is accomplished by providing a piston bowl and air flow pattern within the combustion chamber through intake passage shape and squish action. The shape of the combustion chamber also provides rapid flame propagation even at low speeds and loads. The timing of injection of fuel from the fuel injector is such that under low speed/low load conditions the injector begins its injection at a time when the piston is at the end of its compression stroke and under other running conditions the fuel injector begins its injection during the intake stroke

A direct injected, internal combustion engine combustion chamber configuration that employs a three intake valves per cylinder and direct cylinder injection. Stratification is accomplished by providing a piston bowl and air flow pattern within the combustion chamber through intake passage shape and squish action. The shape of the combustion chamber also provides rapid flame propagation even at low speeds and loads.
摘要:
A number of combustion chamber configurations for direct injected engines wherein the fuel injectors inject at least two fuel patches in circumferentially spaced locations. This fuel is injected into a cavity arrangement formed in the head of the piston, which directs the fuel upwardly toward a pair of circumferentially spaced spark plugs so as to insure complete combustion within the combustion chamber. Embodiments having single and paired cavities in the piston head are disclosed.
摘要:
A direct injected, internal combustion engine combustion chamber configuration that employs a shrouded arrangement for the intake valve seat so as to generate a tumble motion under at least some running conditions. This is accomplished by a shrouding of the intake valve in such a way that the flow direction effects a tumbling motion and also so that the air flow does not adversely affect the flow from the injector nozzle.

A direct injection engine has a fuel injection valve that directs a spray of fuel to each side of a spark plug electrode. The fuel mixes with the air to define a region of relatively richer air-fuel mixture and a region of relatively leaner air-fuel mixture. The electrode is positioned within the relatively leaner region.

A leakage-preventing unit 50 of an absorbent article 1 is formed by elastic members 51 and sheets 52. The leakage-preventing unit 50 includes a central region C and a pair of end unit regions S positioned outside a longitudinal direction L from the central region C.The elastic members 51 includesa fixed unit 51A fixed to the sheet 52 in a state when the elastic members 51 extend in the longitudinal direction L and a free end 51B positioned outside the longitudinal direction L from the fixed unit 51A, which is not fixed to the sheet 52. The end unit regions S includes a joint processing unit 53A in which a joint process for joining the portions where the sheets 52 face each other is performed and a non-joint processing unit 53B in which the joint process is not performed. The free end 51B is arranged in the non-joint processing unit 53B.

The present invention provides an array-type photo module including a filter, which, in each channel, transmits therethrough a portion of emitted light from an incident optical fiber on the opposite side of a gradient-index lens array and reflects another portion of the emitted light from the incident optical fiber toward the gradient-index lens array, and a light-shielding member which is arranged on the opposite side of the filter from the gradient-index lens array, so as to be spaced from the filter and, in each channel, has an opening passing therethrough transmitted light from the filter on the opposite side of the filter. The array-type photo module is easily and inexpensively manufactured, and may be used in a high-density array, with low crosstalk.

An optical module has a structure for reducing the stress applied to a package. The optical module is structured so that an end face of a waveguide (37) of a planar lightwave circuit (30) is joined to a plurality of packages (40) storing therein optical elements so that the waveguide is optically coupled to the optical elements. The optical module includes a housing (3) storing therein a planar lightwave circuit and a plurality of packages in which an upper face of a protrusion (270) formed in the bottom section is fixed to the planar lightwave circuit (30). Each of the plurality of packages (40) is electrically connected to an electric part (22) provided in the housing (3) via flexible printed circuits (271a, 271b).

An imaging apparatus having as a shooting mode a normal shooting mode and a continuous shooting mode for generating a plurality of pieces of image data, includes a setting unit operable to set a shooting mode, an imaging element having as a read mode a normal read mode for outputting image signals of all pixels and a mixing read mode for mixing and outputting an image signal of a predetermined pixel and image signals of peripheral pixels of the predetermined pixel, and a pixel mixing controller operable to control the read mode of the imaging element. The pixel mixing controller controls the imaging element to operate in the mixing read mode when the shooting mode is set to the continuous shooting mode.
