    • An engine analyzer apparatus for use with large internal combustion engines in which a self-closing ball valve is permanently installed on each engine cylinder and an air-cooled adapter may be selectively connected to each valve for communicating the engine cylinder pressure to a transducer while protecting the transducer from overheating and without influencing the operation of the engine. The adapter is cooled principally by compressed air but controlled amounts of water may be injected for additional cooling. An unloading device may be mounted on the ball valve for selectively unloading an engine cylinder during testing.
    • 一种与大型内燃机一起使用的发动机分析仪装置,其中在每个发动机气缸上永久地安装有自闭式球阀,并且风冷适配器可以选择性地连接到每个阀,以将发动机气缸压力传递到换能器,同时保护 换能器过热而不影响发动机的运行。 适配器主要由压缩空气冷却,但可以注入受控量的水以进行额外的冷却。 卸载装置可以安装在球阀上,用于在测试期间选择性地卸载发动机气缸。
