Title (EN) PISTON FOR INTERNAL COMBUSTION ENGINES
(FR) PISTON DE MOTEUR A COMBUSTION INTERNE
Abstract:
(EN) Piston for internal combustion engines of the composite type with a steel top part mounted on an aluminium bottom part which is provided with ring grooves. Said bottom part (2) comprises a circular cavity (3) open upwards, concentric and extending at the back of the bottoms of the ring grooves (5), said cavity being covered by the steel top part (1). Piston for high operating temperatures and pressures, particularly for Diesel engines.
