METHOD FOR OPERATING A MARINE DIESEL ENGINE |
摘要 |
In a marine diesel engine equipped with a plurality of turbochargers, when the turbochargers are switched from single operation to parallel operation or from parallel operation to single operation, surging in the turbocharger to be started or stopped is prevented. The marine diesel engine includes an exhaust pipe (L2) via which an exhaust manifold (6) mounted on an engine body (2) communicates with a turbine part (4a), a turbine inlet valve (10) connected somewhere in the exhaust pipe (L2), a supply pipe (L4) via which a compressor part (4b) communicates with a supply manifold (7) mounted on the engine body (2), a check valve (11) that is connected somewhere in the supply pipe (L4) and that becomes open when the outlet pressure of the compressor part (4b) reaches or exceeds the outlet pressure of a compressor part (3b); an air vent pipe (L9) having one end thereof connected somewhere in the supply pipe (L4) between the compressor part (4b) and the check valve (11), and an air vent valve (12) connected somewhere in the air vent pipe (L9). |
