A path ( 24 ) is formed in an intake tube ( 6 ), which supplies external air to a reciprocating engine ( 4 ). External air flowing from an inlet port to an outlet port of the path ( 24 ). A gaseous fuel path ( 26 ) is connected to the path ( 24 ) at an intermediate location thereof. A gaseous fuel, lighter than air, is supplied through the gaseous fuel path ( 26 ) into the path ( 24 ). A plurality of nets ( 8 ) are disposed in an area of the path ( 24 ) between the outlet port and the gaseous fuel path ( 26 ). The nets ( 28 ) are spaced along the length of the path ( 24 ) with the outer peripheral surface of each net ( 28 ) being in contact with the inner surface of the path ( 24 ).
