摘要： The invention concerns a cast light metal piston of box-type construction for a two-stroke engine having optimum values as concerns casting properties, piston cooling, weight reduction, low noise and mixture transfer. To this end, the piston according to the invention comprises a combination of the following features: the piston blank comprises only one lug in the region of one piston shaft side (3); the wall section (6) connecting the piston shaft (3) to the gudgeon-pin boss (4) has a window-like recess (8) on the lug side; the wall section (7) connecting the piston shaft (3) to the gudgeon-pin boss (4) and remote from the lug side is closed; and the closed wall section (7) is raised upwards (10) relative to the shaft length from the open shaft end (9).

摘要： A piston (1) has a gudgeon pin with a plate-shaped gudgeon pin restraining fixture (5), the outer edge of which is push-fitted in the gudgeon pin hole. The restraining fixture has disc spring characteristics, and on moving the gudgeon pin against the restraining fixture the outer diameter increases and self-escapement occurs.

摘要： In order to achieve good results in terms of the passage of leakage gas (blow-by quantity) and oil consumption in a two-ring piston for internal combustion engines, a combination of a rectangular ring in the piston head-side ring groove with a spring-loaded taper face scraper ring in the piston skirt-side ring groove is proposed, it being proposed that the land be partially recessed under the piston skirt-side groove.

摘要： The cylinder head(1) has a rotary valve(3) made of austenitic cast iron. The bore(2) housing the rotary valve is at least partially coated in the region of the running surface for the rotary valve. The coating is one of nickel with dispersed hard particles or is a hard chrome lining. The cylinder head has at least one carbon sealing ring(8) in abraidable contact with the rotary valve. The sealing ring seals the gap between the rotary valve and valve housing in the region of the gas flow passages.

摘要： The two-stroke IC engine (1) has relatively wide inlet and exhaust ports (2). In order to prevent the piston rings springing radially outwards as the piston passes over the ports (2) each port (2) is provided with a central vertical rib (3). These ribs (3) are likely to cause rubbing marks on the piston skirt. To prevent these marks being formed two small dia. opposite flats are formed on the piston skirt and extend axially over the area which would otherwise come into contact with the ribs (3). No material is removed from the piston top land. USE - Two-stroke IC engine.
