Abstract

Piston combustion engine (1) comprising an engine block with at least one cylinder (2), a cylinder head (3) provided with in­ let and exhaust channels (4,5) and closing off said cylinder at one end, and a piston (9) accommodated in said cylinder which is guided reciprocally between a top dead centre close to said cylinder head (3) and a bottom dead centre at a stroke length therefrom, said piston (9) bearing a number of piston rings (12) that are in sliding contact with the inner wall (13) of said cylinder (2). At least a portion (15) of said inner wall (13) of said cylinder (2) between said cylinder head (3) and the level of the uppermost piston ring (12) at the top dead centre of said piston, has a greater surface roughness relative to that of the surface of the peripheral wall (17) of said piston (9) above the uppermost piston ring (12).
