The invention provides an engine capable of reducing gas pressure in a sub-chamber earlier to ensure good load responsiveness. A gas engine (1) provided with, as combustion chambers for cylinders (11), a sub-chamber (21) for igniting a fuel gas and generating a flame, and a main chamber (20) for combusting a mixture of the fuel gas and air using the flame generated in the sub-chamber (21), the engine being provided with: a sub-chamber main pipe (39) for supplying the fuel gas to the sub-chamber (21); an air supply passage (32) through which air supplied to the main chamber (20) flows; and a connecting pipe (41) communicating from the sub-chamber main pipe (39) to the air supply passage (32). 本发明提供能够更早地减少副室气体压力来确保良好的负载响应性的发动机。燃气发动机(1)具备使燃料气体点火而产生火焰的副室(21)、和使用在副室(21)产生的火焰而使燃料气体与空气的混合气燃烧的主室(20)来作为各气缸(11)的燃烧室，其中，上述发动机具备：副室主管(39)，其向副室(21)供给燃料气体；供气通路(32)，其供向主室(20)供给的空气进行流通；以及连结管(41)，其从副室主管(39)向供气通路(32)连通。
