摘要： The invention relates to a cooling duct piston for an internal combustion engine comprising heat pipes. In order to improve dissipation of heat from the thermally loaded piston areas while preventing thermal tensions, liquid-filled heat pipes that are provided with an evaporator end and a condenser end are disposed in bores of the cooling duct which are oriented towards the bottom of the piston. The heat pipes are arranged such that the evaporator ends terminate at the end of the bores which faces the piston bottom while the condenser ends terminate in the closed cooling duct.

摘要： The invention relates to a lightweight piston comprising heat pipes. The aim of the invention is to simplify the structure of such a piston while at the same time allowing for an improved heat dissipation from the piston areas subject to heat load while avoiding thermal stress. For this purpose, a plurality of liquid-filled heat pipes each having an evaporator and a condenser end is used, whereby the evaporator end is configured by short pipe sections that are oriented in the thickness at bottom towards the focal point and that are interlinked by means of a composite heat pipe extending in parallel to the piston head. At least two pipe sections functioning as the condenser end are coupled with the composite heat pipe in such a manner as to configure, by way of a pipe connection arranged on the condenser ends, a closed coolant cycle between the evaporator end, composite heat pipe and condenser end of the heat pipe.

摘要： A piston for an internal combustion engine, has a piston crown, two pin bosses, and pin bores introduced into the pin bosses. Respective lubricating grooves are formed in the nadir and equator regions of the pin bores. In order to improve the lubrication of the pins, the lubricating grooves are arranged in the radially inner edge area of the respective pin bore and additionally in a plane lying at an angle to the piston axis, such that the lubricating grooves open into the radial inner faces of the pin bosses, where lubricating oil can enter the lubricating grooves. The lubricating grooves are produced by a lathe tool, the rotational axis of which is tilted relative to the pin bore axis and which is moved in a direction pointing away from the piston crown during the turning.

摘要： The invention relates to a hybrid pin (14) for connecting a piston for an internal combustion engine to a piston rod, the hybrid pin (14) consisting of a sleeve (3) made of steel and consisting of a core (2) which is pressed into the sleeve (3) and which is made of a lightweight metal alloy that can be cold-formed. The inner surface of the sleeve (3) has a profile, whereby an elastic elongation of the core (3) in the axial direction after the core (3) is pressed into the sleeve (3) is prevented to such an extent that the sleeve (3) is longer than the core (2) at both ends of the hybrid pin (14).
