SYSTEM FOR REDUCING EMISSIONS IN CATALYTIC CONVERTER EXHAUST SYSTEMS |
摘要 |
<p>The invention relates to a system for reducing emissions in catalytic converter exhaust systems for an internal combustion engine. The invention comprises air-fuel mixture forming means for providing a mixture of air-fuel to the engine, a catalytic converter for purifying an exhaust gas mixture from the engine, and a control unit adapted for controlling the mixture forming means so that an excess of hydrogen is generated in the exhaust gas mixture during the start-up of the engine. According to the invention, the excess of hydrogen is maintained essentially unburnt within the catalytic converter so as to provide a short light-off time for the catalytic converter.</p> |
