摘要： A hollow engine valve includes a shaft portion and an umbrella portion of which diameter is enlarged to form an umbrella shape to be provided on a base end of the shaft portion, a cooling material being enclosed in a hollow portion that is at least formed inside the shaft portion. The shaft portion comprises a first shaft portion in a tip end side, a second shaft portion that is provided in a base end side to have an outer diameter larger than that of the first shaft portion, and a stepped portion formed by a difference in the outer diameters between the first and second shaft portions. A wall thickness of the stepped portion is larger than that of the second shaft portion.

摘要： A valve having a sleeve-like screening element for protecting an internal combustion engine against deposits in a region extending up from a hollow throat to a stripping edge. The screening element has a separate contactor guide surface for the combustion air supplied to the combustion chamber whose surface temperature is lower than the critical temperature for deposits at which fuel particles coke.

摘要： A fuel injection valve is caused to inject fuel in a latter half of a compression stroke in such a manner that a fuel concentration immediately before start of combustion is higher in a middle portion of a combustion chamber than in an outer peripheral portion thereof in a low load range where the engine load is lower than a predetermined set reference load. An intake valve driving device is controlled in such a manner that an intake valve closing timing in the low load range is advanced on a retard side with respect to an intake bottom dead center in a case where the engine speed is high, as compared with a case where the engine speed is low, and intake air within a cylinder is blown back toward an intake port at least in a range where the engine speed is low.

摘要： A method for producing a hollow valve of an internal combustion engine may include providing a hollow valve stem, a valve cone, and a valve bottom; pushing the valve cone over the valve stem via a press fit, wherein the valve cone includes an outer surface transitioning to the valve stem to define a testing surface; and welding the valve cone to the valve stem via at least one of a laser beam and an electron beam, wherein the welding occurs such that no melting of the outer surface in the region of the testing surface of the valve cone occurs.

摘要： A gas shuttle valve is for an internal combustion engine, in which a valve plate, as a sealing element, a tubular valve shaft, as a guide element, and a thrust part, which seals the end of the valve shaft opposite to the valve cone, as a stop for a valve operating element having a support for a typical valve spring, are welded to one another. This production method is distinguished by a precisely fitted assembling of these parts to a predetermined length measure, which precedes the permanent bonding of the valve shaft and thrust part.
