ABSTRACT:
In a two-cycle engine provided with crankshaft controlled fuel injection, fuel is supplied from a fuel tank to an inlet (23) having an adjusting means. The fuel flows via a connection (27) to a passage (39) in the crankshaft (13). Gaskets and O-rings are provided to seal off against the crankshaft and crankcase. The positions of the connection (27) and the crankshaft passage (39) are selected so as to obtain communication when underpressure prevails in the crankcase whereby fuel is sucked in and thrown out by centrifugal force via a nozzle (31).
