An air intake apparatus for an internal combustion engine, the air intake apparatus includes: an air intake apparatus main body portion introducing air into a cylinder; a port portion provided integrally with a downstream side end portion of the air intake apparatus main body portion and inserted into an air intake port in a cylinder head; an air intake passage formed inside the air intake apparatus main body portion and the port portion, and through which an air-fuel mixture containing air and fuel flows; an injector provided in the air intake apparatus main body portion and introducing the fuel into the air intake passage; and a heater heating the fuel introduced by the injector. The injector is disposed at a position where the fuel is capable of being injected into the heater.

Air intake apparatus for internal combustion engine

This disc rotor has a hat portion having a cylindrical portion and a sliding plate portion having an insertion hole into which the cylindrical portion is inserted, being connected together with the hat portion in a state in which the cylindrical portion protrudes from the insertion hole. The coupling is achieved by pinching an inner peripheral edge of the sliding plate portion between a first portion and a second portion that are formed in the cylindrical portion. The second portion is formed by plastically deforming an outer peripheral side of the cylindrical portion toward the first portion.

An airflow control valve structure includes a metallic pivot shaft-and a valve body. The valve body includes a connection portion connected to the pivot shaft and a resin valve portion. The pivot shaft includes first and second pivot shaft side press-fit portions. The connection portion includes a first valve side press-fit portion formed integrally with the valve portion and a metallic fitting member including a second valve side press-fit portion. The first valve side press-fit portion is fitted to the first pivot shaft side press-fit portion at an angular position at which a phase of the valve portion is matched with a phase of the pivot shaft. The second valve side press-fit portion is fitted to the second pivot shaft side press-fit portion. The first pivot shaft side press-fit portion is longer than the second valve side press-fit portion.

In a differential apparatus component (ring gear-integrated with differential case), a differential case and a ring gear are formed integrally and seamlessly of cast steel. Cast Steel is preferably composed of 0.3 to 1.0% by mass of silicon (Si), 0.5 to 1.2% by mass of manganese (Mn), 0.1 to 0.5% by mass of vanadium (V), 0.01 to 0.05% by mass of tin (Sn), 0.1 to 1.5% by mass of chromium (Cr), 0.2 to 1.0% by mass of copper (Cu), and the rest composed of iron (Fe) and unavoidable impurities.

Differential apparatus component, differential apparatus therewith and manufacturing method thereof

A powder-containing oil-based lubricant for die contains 60 to 99% by mass of an oil-based lubricant consisting of oil, 0.3 to 30% by mass of a solubilizing agent, 0.3 to 15% by mass of an inorganic powder and 7.5% by mass or less of water, the lubricant being electrostatically applied to a die. The powder-containing oil-based lubricant may be applied to a die by electrostatic spraying. The electrostatic spray apparatus includes a device that imparts static electricity to the powder-containing oil-based lubricant and an electrostatic spray gun installed on a multi-axis robot.

Powder-containing oil based mold lubricant and method and apparatus for applying the lubricant

An apparatus and process for manufacturing a disc rotor made of a metal-based composite material, which enables stabilization of a preform support within a disc rotor casting cavity while minimizing likelihood of damaging of preforms. The apparatus comprises a lower dieand a movable core assemblywhich constitutes a disc rotor casting cavity; a preform supporting portionwhich is provided on a movable core assembly; a pressurizing and shaping portionof an upper diefor applying pressure upon a molten metal accommodated in the cavity; and a preform biasing mechanismhaving a biasing facewhich can be brought into a face-to-face contact with the upper face of a preformwhich is supported on the preform supporting portion. On application of pressure upon the molten metal, the preform biasing mechanismbiases the preformvia the biasing faceto prevent the preformfrom being shifted due to an increase in the pressure upon the molten metal.

Apparatus and process for manufacturing disc rotor

A disk rotor is produced using pre-forms. A manufacturing deviceincludes lower moldand upper mold. The lower moldincludes support block, main body part of the lower mold, inclined pins, core elementsand slider. In securing and supporting pre-formsA,A, a cylinderis actuated to cause upward movement of the support blockand the main body part of the lower mold, during which movement, core elementsand sliderare slid relatively outwards along inclined pins. In this state, the pre-formsA,A are guided to preset sites. The support blockand the main body part of the lower moldare then moved downwards, during which movement, core elementsand sliderare slid relatively inwards along the inclined pins. In this state, the pre-formsA,A are supported and secured stably to define a cavity.
