Abstract

A gas engine (10), with at least one cylinder (11), wherein the or each cylinder (11) comprises a main combustion chamber (12) for combusting a fuel gas-air mixture and a scavenged precombustion chamber (13) that is coupled to the main combustion chamber (12) via an overflow duct (14), and with at least one exhaust gas turbocharger (15), which comprises a turbine (16) for expansion of exhaust gas leaving the or each cylinder (11) and a compressor (18, 22) for compressing air to be fed to the or each cylinder (11), and with a plurality of air paths for air to be fed to the or each cylinder (11), wherein via a first air path (17) at least air can be compressed with a first compressor (18) and fed to the main combustion chamber (12) of the or each cylinder (11), and wherein via a second air path (21) a fuel gas-air mixture can be compressed with a second compressor (22) and fed to the precombustion chamber (13) of the or each cylinder (11).
