Method for reducing methane exhaust emissions from natural gas-fuelled engines. |
摘要 |
<p>High conversion efficiencies for methane, other unburned hydrocarbons, carbon monoxide and nitrogen oxides can be obtained from a natural gas or methane-fuelled engine by operating the engine with an air-fuel ratio within a range that includes the stoichiometric air-fuel ratio and extends to the fuel-rich side and by employing in combination with the engine a platinum or platinum and palladium noble metal catalyst for treatment of the engine exhaust gases. <IMAGE></p> |
