Abstract

A shield element (9) is positioned in the bottom of cylinder bush (3) to reduce the quantity of water droplet which enters the cylinder bush during process movement of piston. The cylinder bush consists of fixed scavenging-air slit (4) together with the supply portion of the piston which the diesel engine (1) can move within the cylinder bush and the air for scavenging air. The scavenging air carries the water droplet which enters the cylinder bush. An independent claim is also included for a shielding method for cylinder bush.
