Zusammenfassung:The fuel injection arrangement for a cylinder (33) of a four- stroke piston engine comprises a first fuel injection nozzle (3) and a second fuel injection nozzle (4), the total cross- sectional area of the nozzle holes (4a) of the second nozzle (4) being greater than the total cross-sectional area of the nozzle holes (3a) of the first nozzle (3), and the nozzle holes (4a) of the second nozzle (4) being arranged so that a greater part of the fuel injected through the second nozzle (4) is injected towards an intake valve side (25) than towards an exhaust valve side (26) of the cylinder (33).
