    • The present disclosure refers to a gas fuel admission system (1) for a gas fired engine (5). A gas pressure regulating unit (15) includes a gas pressure regulating unit inlet (20) and a gas pressure regulating unit outlet (25). The gas pressure regulating unit (15) is configured to receive gas and to discharge the gas at an injection pressure. An engine gas inlet (6) is configured to direct gas into the at least one combustion chamber (10). A gas admission valve (40) is configured to admit the gas having an injection pressure at a predetermined time for a predetermined duration into the engine gas inlet. A gas pressure relief device (60) is fluidly connected to the gas conduit (35) and it is configured to relieve overpressure of the gas in the gas supply conduit (35), if a pressure differential between the injection gas pressure and the intake air pressure is above a predetermined threshold. A specific engine control module (70) is configured to control the gas admission valve (40) in response to inputs from various sensing devices (70, 80).
    • 本公开涉及一种用于燃气发动机(5)的气体燃料进入系统(1)。 气体压力调节单元(15)包括气体压力调节单元入口(20)和气体压力调节单元出口(25)。 气体压力调节单元(15)构造成接收气体并以注射压力排出气体。 发动机气体入口(6)构造成将气体引导到至少一个燃烧室(10)中。 气体入口阀(40)构造成将具有预定时间的喷射压力的气体预定持续时间允许进入发动机气体入口。 气体释放装置(60)流体地连接到气体导管(35),并且其构造成在气体供给管道(35)中释放气体的过压,如果喷射气体压力和进气之间的压力差 压力高于预定阈值。 特定的发动机控制模块(70)构造成响应于来自各种感测装置(70,80)的输入来控制气体进入阀(40)。
