Abstract: The present invention is a burner apparatus (S1, S2, S3, S4) that combusts air-fuel mixture (Y) of an oxidizing agent and fuel. This burner apparatus (S1, S2, S3, S4) includes a partitioning component (8) that separates an ignition chamber (R2) where the air-fuel mixture (Y) is ignited and a combustion holding chamber (R3) where the combustion of the air-fuel mixture (Y) is maintained such that the air-fuel mixture (Y) is able to pass between them, wherein the partitioning component (8) adjusts the flow rate of the air-fuel mixture (Y) that is supplied from the ignition chamber (R2) to the combustion holding chamber (R3).

Abstract: In a premixed compression ignition diesel engine 1 with fuel being injected midway of a intake passage 15, an intake port 6 is formed with an orifice 10 which is throttled in passage cross-sectional area at least in an opening operation of an intake valve 7. This prevents adhesion of the fuel to an inner wall of the intake passage and promotes atomization of the fuel. A combustion chamber is fed with the sufficiently atomized fuel, which prevents combustion failure in the combustion chamber to attain reduction of particulate matters.

Abstract: In a diesel engine 1 with fuel injection valves 6a and 6b for injecting fuel 5a, 5b into a combustion chamber 4, respectively, the valves 6a and 6b are arranged such that they are opposed to each other horizontally and diametrically of the combustion chamber 4 in a plan view and are out of alignment in height to each other axially of a cylinder 2. With the valves 6a and 6b being positioned close to and away from the cylinder head 7, respectively, an upper surface of the piston 3 has a rising gradient extending from its side adjacent to the valve 6b toward its side adjacent to the valve 6a up to diametrically halfway of the piston 3.

Abstract: In a diesel engine including a fuel injection valve for injection of fuel into a combustion chamber to produce sprays in the chamber, an axis of the valve is deviated radially outwardly of an axis of a cylinder, so that the valve is positioned close to an inner periphery of the cylinder. Nozzle holes of the valve are grouped into two groups with respect to a line formed by connecting, in plan view, the axis of the valve with the axis of the cylinder. The sprays injected from the nozzle holes advance in a fan-like manner in the plan view and strike against the inner periphery of the cylinder on a side away from the valve.

Abstract: A stack of 50 layers of a first pitch-base carbon fiber sheet is formed, two sets of stack each having two second pitch-base carbon fiber sheets stacked therein are fabricated. At this time, the second carbon fiber sheets have a thermal expansion coefficient larger than that of the first carbon fiber sheet. Next, the stack of the first carbon fiber sheet is then held between two sets of stack of the second carbon fiber sheets. The stack of the first and second carbon fiber sheets are then impregnated with an epoxy-base resin composition and the resin is solidified. As a result a prepreg composed of the first and second carbon fiber sheets and the resin component composed of the epoxy-base resin composition is obtained. Thereafter, interconnections and the like are then formed on the prepreg, to thereby complete a multilevel interconnection board.
