    Abstract: The present invention achieves technical advantages as an engine compartment drainage system that allows fluid on an engine deck to exit an engine compartment, while shielding fluid from airflow. A fluid drainage apparatus utilizes a funnel member to direct fluid to an external drain line. A drain shield circumscribes the top end of the funnel member and upwardly extending therefrom and directs airflow away from the funnel member. A plurality of deck holes are disposed in the drain shield, such that fluid on the deck can enter the funnel member and exit the engine compartment. A fluid drainage system, disposes the fluid drainage apparatus in an engine deck to allow fluid on the deck to enter a funnel member of the apparatus and direct it toward the external drain line.

    Abstract: A method of conducting an engine power assurance check includes performing a first engine power assurance check wherein the first engine power assurance check is judged as passing or failing based on power performance values calculated assuming the presence of a substantially clogged or blocked inlet barrier filter and in response to a fail result of the first engine power assurance check, performing a second engine power assurance check wherein the second power assurance check is judged as passing or failing based on power performance values calculated assuming at least one of no inlet barrier filter being installed and an open bypass of an installed inlet barrier filter.

    Abstract translation: 执行发动机功率保证检查的方法包括执行第一发动机功率保证检查，其中基于基本上堵塞或阻塞的入口阻挡过滤器的存在而计算的功率性能值，将第一发动机功率保证检查判断为通过或失败，并且 响应于所述第一发动机功率保证检查的故障结果，执行第二发动机功率保证检查，其中所述第二功率保证检查基于假定安装无入口阻挡滤波器的至少一个而计算的功率性能值被判断为通过或失败; 安装的入口挡板过滤器的开路旁路。
