Cylinder for an internal combustion engine

A cylinder arrangement for a two-stroke, crankcase scavenged internal combustion engine, said cylinder arrangement comprising:

• a cylinder defined by a peripheral cylinder wall and adapted for accommodating a reciprocating piston therein;
• a wall passage extending from an air inlet port, said air inlet port being located exteriorly to said cylinder wall, said wall passage extending at least partially obliquely upwards and through said cylinder wall to an air connecting port located interiorly to said cylinder wall, said wall passage providing a fluid flow passage across said cylinder wall and said wall passage being laterally located with respect to said air-fuel inlet pipe;
• and
• an air-fuel inlet pipe directed at least partially obliquely downwards and through said cylinder wall.

• and
• an air-fuel inlet pipe directed at least partially obliquely downwards and through said cylinder wall.
