The crankcase inducts a fuel/air mixture and is connected to the scavenging ports (31, 31') by means of transfer ducts (3, 3') which, as the piston (13) is travelling from a lower position towards a higher position, are inducting pure air let in from connecting ports (8, 8') near the scavenging ports (31, 31') in the cylinder (15). The transfer duct (3, 3') volume is less than 20 % of a volume swept by the piston (13) during an entire revolution of the crankshaft (18). Recesses (10, 10') are formed in an outer periphery of the piston (13), said recesses (10, 10') co-operating with the connecting ports (8, 8') in the cylinder wall for controlling the filling of the transfer ducts (3, 3') with air. An inlet tube (22) in the cylinder wall supplies the air/fuel mixture, said inlet tube (22) being connected to the crankcase (16) and covered by the piston (13) as the piston (13) is in the lower position, and open to the crankcase (16) as the piston (13) is in the higher position.

Abstract: The present invention relates to a set-up and a method for repeatedly sending longitudinal displacement pulses through a length of optical fibre, the set-up using an actuator arrangement for exciting longitudinal displacement pulses, or waves, in an optical fibre. The arrangement comprises a bracket, a washer element, a piezo member arranged between the bracket and the washer element, and an optical fibre that is engaged with and extending through a passage in the washer element. The piezo member is operative, responsive to an applied voltage, to displace the washer element and the fibre engaged therewith, in the longitudinal direction of the fibre, with respect to the bracket. Thereby, a longitudinal displacement pulse may be excited in the optical fibre. The actuator arrangement may also, in the set-up according to the invention, operate as a sensor for sensing longitudinal displacements in optical fibres.
