The present disclosure provides a large turbocharged two-stroke internal combustion engine (100) of the uniflow type and a method of operating such an engine (100). The engine (100) is configured to supply pressurized scavenging and/or exhaust gas to a pressurized gas consumption device (200). The engine includes: a plurality of cylinders; an air intake system; an exhaust system; one or more turbochargers that have a turbine; a fuel system; a bypass system for supplying bypass pressurized gas to the pressurized gas consumption device by withdrawing a controlled amount of scavenging gas from the intake system so as to bypass the engine and/or by withdrawing a controlled amount of pressurized exhaust gas from the exhaust system so as to bypass the turbine; and a controller configured to adjust an amount of bypass pressurized gas supplied to the consumer according to the sensed scavenging pressure and/or exhaust temperature. The controller is configured to operate the engine in a manner that takes various adjustment measures to maximize the scavenging pressure and/or maximize the scavenging bypass mass flow.

    本公开提供了单流型大型涡轮增压二冲程内燃发动机(100)以及操作这种发动机(100)的方法,发动机(100)构造成向加压气体消耗装置(200)供应加压的扫气和/或排气。发动机包括:多个气缸;进气系统;排气系统;一个或更多个涡轮增压器,其具有涡轮;燃料系统;旁通系统,其用于通过从进气系统取出受控量的扫气从而绕过发动机和/或通过从排气系统取出受控量的加压排气从而绕过涡轮,向加压气体消耗装置供应旁通的加压气体;以及控制器,其配置成根据所感测的扫气压力和/或排气温度对供应至消耗装置的旁通加压气体的量进行调节。控制器配置成以进行各种调整措施以使扫气压力最大化和/或使扫气旁通质量流量最大化的方式操作发动机。
