Abstract

A multisectional piston for opposed-piston, slider-crank-drive internal combustion engines. The piston has a ceramic skirt (1), a skirt head (2), and a ceramic piston head (3) with fire land (4). The ceramic piston head is provided with annular groove (6) for receiving a slotted, ceramic piston ring (7) and is seated on the skirt head (2). A ceramic, common centering sleeve (5) fixes the skirt and head. Metal or metal alloy centering piece (8) fixed on the piston rod (12) in snug fit (14) has a base plate (9) on which the skirt head seats. An end cover (10) seats on the piston head and has a centering hub (11) axially spaced by a gap (23) from the centering piece. In assembly, the skirt head and piston head are axially clamped between the end cover and the base plate by a screw connection (13).
