<p>In an internal combustion engine installation, an exhaust arrangement (3) includes an exhaust gas separation membrane (22) which separates the exhaust gas from the engine (17) into an oxygen-enriched stream (23) and an oxygen depleted stream (24). The oxygen depleted stream (23) is presented to a converter (25) whereby oxides of nitrogen are diminished whilst the oxygen-enriched stream (24) may be used to supplement oxygen enriched air supplied to the engine from an inlet air separation membrane (8). A plasma generator (19) uses the nitrogen enriched air from the inlet air separation membrane to create free radicals of nitrogen to react with oxygen-rich exhaust from the engine.</p> |
