LARGE SLOW-RUNNING TURBOCHARGED TWO-STROKE INTERNAL COMBUSTION ENGINE WITH SCAVENGE AIR RECEIVER AND EXHAUST GAS RECEIVER

摘要

PROBLEM TO BE SOLVED: To enable Exhaust Gas Recirculation (EGR) in a large slow-running turbocharged two-stroke internal combustion in-line engine of the uniflow type with crosshead.SOLUTION: A scavenge air receiver 2 is divided into at least two scavenge air receiver sections. A first scavenge air receiver section 2a is connected to one or more primary cylinders 1, and a second scavenge air receiver section 2b is connected to one or more secondary cylinders 1. The first scavenge air receiver section is provided with an inlet and the second scavenge air receiver section is provided with an inlet. An exhaust gas receiver is divided into at least two exhaust gas receiver sections. A first exhaust gas receiver section 3a is connected to one or more primary cylinders 1, and a second exhaust gas receiver section 3b is connected to one or more secondary cylinders 1. The first exhaust gas receiver section 3a is provided with an inlet, and the second exhaust gas receiver section 3b is provided with an inlet. The second scavenge air receiver section can be selectively connected to the first scavenge air receiver section, and The second exhaust gas receiver section can be selectively connected to the first exhaust gas receiver section.
