<p>The invention relates to a fuel injection arrangement for piston engine comprising at least one fuel injector by means of which fuel may be injected into a combustion chamber of the engine, the fuel injector comprising at least one fuel injection valve arranged to meter the fuel into the combustion chamber, the fuel injection arrangement further comprising an intensifier piston arrangement comprising a piston space and a piston member therein having a first area which is arranged to be effected by a work fluid and which first area at least partially borders a first work space of the intensifier piston arrangement; and the piston member having a second area which at least partially borders a second work space of the intensifier piston arrangement, the second work space being arranged in flow connection with the at least one injection valve of the injector. The intensifier piston arrangement comprises a counter member and the piston member is provided with a longitudinally extending cavity providing a space into which the counter member is arranged to extend at least partly, and the second area is at least partly defined at least partly by the piston member and the counter member.</p> |
