In one aspect of the present disclosure, a pre-combustion chamber of an engine is disclosed. The pre-combustion chamber comprises a body having an external surface and an internal surface. The internal surface defines an ignition chamber. The pre-combustion chamber further comprises a first conduit adapted to supply a cold gas on the internal surface of the pre-combustion chamber. The pre-combustion chamber further comprises a second conduit adapted to supply a gaseous fuel into the pre-combustion chamber. The flow of the cold gas is regulated into the pre-combustion chamber to reduce temperature inside the pre-combustion chamber.
