Abstract

Internal combustion engine for gaseous fuels having a combustion chamber (2) in which gaseous fuel is burned. The gaseous fuel is kept at an operating pressure in a gas tank (7) and fed to the combustion chamber (2) via a supply line (6). The combustion chamber (2) is connected to a fresh air line (10) through which ambient air is fed to the combustion chamber (2). The exhaust gas from the combustion chamber (2) is fed to an exhaust gas catalytic converter (14) via an exhaust pipe (13). A pressure relief line (16, 16′) with a switchable release valve (17, 17) branches off from the supply line (6), via which gaseous fuel can be discharged from the supply line (6).
