    • PURPOSE: A scavenging performance monitoring system and method for measuring process parameters in a large-size two-stroke diesel engine performing longitudinal evacuation are provided to reduce safety margins at all sides of the diesel engine layout by improving the reliability and availability of the diesel engine. CONSTITUTION: In an scavenging performance monitoring system for measuring process parameters in a large-size two-stroke diesel engine(2) performing longitudinal evacuation, fuel is supplied by an injection nozzle to a cylinder(4) of the diesel engine. A scavenging slot(6) is installed in the inlet side of the cylinder to supply a certain amount of scavenging air(7). An exhaust valve(8) is installed on a cylinder cover(9) of the cylinder to discharge combustion gas. Fresh air(11) is inhaled by an exhaust gas turbocharger(12) and supplied as scavenging air to the cylinder at specific pressure so that an ignition gas mixture is generated from the scavenging air and fuel within the cylinder. First and second oxygen sensors(131,132) are installed in the actuating surface of the cylinder to evaluate the scavenging performance in the cylinder.
    • 目的:提供一种用于测量大型二冲程柴油机进行纵向疏散的过程参数的清扫性能监测系统和方法,以通过提高柴油机的可靠性和可用性来降低柴油机布置各侧的安全裕度 。 构成:在用于测量大尺寸二冲程柴油机(2)中进行纵向抽空的过程参数的扫气性能监测系统中,燃料由喷嘴提供给柴油发动机的气缸(4)。 扫气槽(6)安装在气缸的入口侧,以提供一定量的扫气(7)。 排气阀(8)安装在气缸的气缸盖(9)上以排出燃烧气体。 新鲜空气(11)由废气涡轮增压器(12)吸入,并以特定压力作为清扫空气供给到气缸,从而从气缸内的扫气和燃料产生点燃气体混合物。 第一和第二氧传感器(131,132)安装在气缸的致动表面中,以评估气缸中的清扫性能。
