摘要： A piston for an internal combustion engine is described, the piston having a lower crown portion and an upper crown portion, the upper crown portion including a combustion bowl and a piston ring-groove belt of generally annular form depending from the outer periphery of the crown surface, the lower crown portion comprising a generally circular plate member having an upstanding ring on the upper surface thereof, the upper crown portion and the lower crown portion being joined together by retention means between the combustion bowl and the upstanding ring, and between co-operating spigot and socket means formed on the base of the combustion bowl and on the plate member, to prevent withdrawal by axial forces, and there being an oil cooling gallery defined between the upper crown portion and the lower crown portion.

摘要： A lubricating system is disclosed which includes a splash cooling of the pistons of an internal-combustion engine by spraying nozzles, the cooling jets of which are aimed at the interior surfaces of the pistons. In order to achieve, after the start of an internal-combustion engine, a rapid buildup of the lubricant pressure, the lubricant supply to the spraying nozzles is interrupted in this initial operating phase. Since, in the starting phase, the lubricating oil supply to the camshafts can be reduced considerably or can even be switched off completely without damaging the bearings, the spraying nozzles and the camshafts receive a common lubricating oil supply which can be controlled centrally by means of control valves. It is advantageous that already existing lubricant ducts may be used, and the spraying nozzles can be constructed in a simple manner without any integrated control valves. It is also advantageous that the spraying nozzles must no longer be arranged at the central main duct above the crankshaft, which is disadvantageous with respect to accessibility and space conditions, but in the area of the camshafts which, in the case of a V-Engine, may be arranged in an advantageous lateral crankcase area.

摘要： A barrel machine, more particularly a barrel engine cooled by means of turbines (5, 6) disposed around a central shaft (4) and distributing the outside air from the central part of the engine, more particularly inside the pistons and liners. Water and oil can therefore be eliminated, more particularly if an aerosol is used as coolant.

摘要： The present invention provides an improved cooling system for a reciprocating piston engine. The engine is of the type having at least one cylinder and a piston movable between a top dead and bottom dead center. The cooling system comprises a housing or coolant jacket which encircles the outer end of the cylinder and extends towards the inner end of the cylinder. The coolant jacket, however, terminates short of the inner end of the piston when the piston is at its top dead position. A fluid passageway is formed through the housing and has both an inlet and outlet. Liquid coolant is supplied under pressure to the inlet port on the housing. The coolant flows through the lower section of the water jacket surrounding the piston area thus achieving uniform adequate cooling of both the combustion chamber and piston. In addition, an oil nozzle mounted within the engine crankcase directs a jet of oil onto the inner surface of the piston dome for further cooling of piston and subsequently supplements cooling of the cylinder barrel and head. The oil jet is the primary cooling mechanism for the section of the barrel not enclosed by the water jacket.

摘要： An oil cooled piston particularly for two cycle direct injection diesel engines offers improved cooling through increasing of the combustion bowl rim radius and modifications to the understructure to provide alternate perforate gussets permitting an increased number of rim cooling ribs. An angular break from the rim radius to the squish land offsets efficiency impairment from the larger rim radius.

摘要： A two-piece piston assembly comprises an upper portion or a ring carrier part that may be made of malleable iron, cast iron, or a similar iron, and a lower portion or cross-head part, referred to as a skirt, that may be made of aluminum or an alloy thereof. The assembly is configured to increase the contact of cooling liquid with the underside of the crown and eliminate problems accompanying undue heating in this area of the piston. The cocktail-shaker action of the two-piece piston assembly is employed to enhance the cooling effect. A separate cup-like device is secured around the outside of the lower end of the crown member of the piston and is thus positioned between the upper and lower portions of the piston to retain the oil and effectively deliver it to the underside of the crown.
