Abstract

Internal combustion engine with pistons, which between the first and the second piston grooves (17, 18) have a peripheral groove (20) which serves as a collection chamber for blow-by gases. The cylinder block of the engine has an evacuation channel (9) for each cylinder. The channel opens up in the cylinder barrel (7) and in the inlet channel of the engine and joins the crank case (6) with the inlet channel during approximately half of the piston stroke from upper dead centre. After approximately half the piston stroke the collecting chamber of the piston is connected with the evacuation channel. The piston is provided with a shield (21) which prevents oil droplets from entering the evacuation channel.
