摘要： PROBLEM TO BE SOLVED: To provide an auxiliary chamber type gas engine capable of enhancing efficiency by advancing the ignition timing and preventing the occurrence of knocking. SOLUTION: In the auxiliary chamber type gas engine (100) for combusting a mixture of fuel gas and air in a main combustion chamber (10) by injecting a flame (F2) from the tip (61) of an auxiliary chamber projecting to the main chamber (10), a fuel gas injection mechanism (8) is arranged in the intake ports (4A, 4B). The mixture of fuel gas and air produces a swirl in a main combustion chamber (10) in an intake stroke so that fuel gas concentration in the region (a central region) in the vicinity of the tip (61) of the auxiliary chamber in the main combustion chamber (10) is decreased in an intake stroke (center lean).
