Abstract: A two-stroke, U-type uniflow engine includes a cylinder block forming parallel first and second cylinders and a common combustion chamber connecting the first and second cylinders. First and second pistons are mounted for reciprocal, linear movement within the first and second cylinders respectively. The engine also includes a crank shaft having a crank pin and a one-piece forked connecting rod connecting each of the first and second pistons to the crank pin. The connecting rod is elastically, bilaterally flexible to accommodate variations between a maximum distance between the first and second pistons and a minimum distance between the first and second pistons and is in a relaxed state halfway between the maximum distance and the minimum distance. The central wall has a slot for passage of the connecting rod therethrough and angled notches which correspond to maximum angles of the connecting rod. The connecting rod is designed to minimize weight and length and the engine bore and stroke are selected to minimize the difference between the maximum and minimum distance of the wrist pin displacement in order to reduce vibrations and to increase engine output by maintaining high crankcase compression.

Abstract: A piston is manufactured by incorporating a reinforcement which is formed at least in part by a fibre material and which is so non-uniform as to provide differing characteristics in the cast piston in predetermined differing regions of the piston. For example, the volumetric density of the fibres may be different in one region of the reinforcement as compared with another region in order to produce a more resistant region in the cast piston. Additionally or alternatively, the reinforcement may hold finely divided materials which combine with the piston material during casting to give improved properties. Examples of this are the incorporation of particles of silicon, silicon carbide or silicon nitride to improve wear and/or the incorporation of molybdenum disulphide and tungsten disulphide or graphite to improve lubrication.

Abstract: The invention relates to a carbon piston for an internal combustion engine, especially for passenger cars and trucks. Said piston comprises a piston head (1), a firing land (2) which axially adjoins the piston head, an annular section (3) and a piston skirt having a hub bore for accommodating a piston pin, the skirt wall having thickened portions (51) opposite each other on the skirt interior to form the hub. Said thickened portions extend into the underside (12) of the piston head with a rounded portion, the underside of the piston head forming an arched surface (12) in the region between the thickened portions (51), said arched surface adjoining the thickened portions at least in the upper region of the hub bore. The piston has a carbon matrix which is infiltrated by a light metal or a light metal alloy.

Abstract: Amagnesiumalloy for casting according to the present invention is characterized in that , when the entirety is taken as 100% by mass, it includes copper (Cu) in an amount of from 0.5% by mass or more to 10% by mass or less, calcium (Ca) in an amount of from 0.01% by mass or more to 3% by mass or less, and the balance comprising magnesium (Mg) and inevitable impurities.
Since the magnesium alloy for casting according to the present invention includes Cu whose heat conductivity is high in a predetermined amount, it is good in terms of heat-conducive ability. The heat-conductive ability is improved by carrying out heat treatment. Moreover, in the magnesium alloy for casting according to the present invention being in as-cast state, grain-boundary crystallized substances including Cu and Ca constitute three-dimensional networks in grain boundaries between Mg crystalline grains. In the network-shaped grain-boundary crystallized substances, grain-boundary sliding, which becomes active when they become high temperature, is suppressed, and thereby high-temperature strength and creep resistance improve.
