Lean gases, such as gases of low methane content from landfill, are used to operate a gas engine with a rich gas line (1) and a lean gas line (2), which open into a common gas line (3) leading to a gas mixer. An additional gas mixer (7) is provided in the lean gas line, to which a by-pass line from the rich gas line is connected, so that rich gas can mix with the lean gas in a Venturi arrangement. Preferably the pressure of the rich gas in the by-pass line is controlled as a function of the pressure of lean gas at the entry to the additional gas mixer. |
