GASOLINE ENGINE WITH AN EXHAUST SYSTEM FOR COMBUSTING PARTICULATE MATTER |
| 摘要 |
A gasoline engine having an exhaust system comprises means for trapping particulate matter (PM) from the exhaust gas and a catalyst for catalysing the oxidation of the PM by carbon dioxide and/or water in the exhaust gas, which catalyst comprising a supported alkali metal. The invention further includes a method of combusting PM from a gasoline engine in CO2 and/or H2O from the exhaust gas at temperatures in excess of 500° C., which method comprising trapping the PM and contacting it with a catalyst comprising a supported alkali metal. |

1. A system comprising a three way catalyst (TWC) adapted for simultaneously oxidizing CO and HC and reducing NOx of an exhaust gas from a gasoline engine, means for trapping particulate matter (PM) of <100 nm from the exhaust gas and a catalyst for catalysing the oxidation of the PM by at least one of carbon dioxide (CO2) and water (H2O) in the exhaust gas, which catalyst consists of a supported alkali metal, wherein the supported alkali metal is disposed downstream of the TWC and is disposed relative to the means for trapping in order to effect contact between the supported alkali metal and the particulate matter. |
