  • Exhaust system with a reformer catalyst
    Patent number: 8984864
    Abstract: An exhaust system for treating exhaust gas from an internal combustion engine is disclosed. The system comprises a three-way catalyst (TWC), a fuel reformer catalyst located downstream of the TWC, and a fuel supply means located upstream of the fuel reformer catalyst. The exhaust gas is split into two portions. The first portion of the exhaust gas bypasses the TWC and contacts the fuel reformer catalyst in the presence of fuel added from the fuel supply means, and is then recycled back to the engine intake. The second portion of the exhaust gas is contacted with the TWC and is then utilized to heat the fuel reformer catalyst before being expelled to atmosphere. The exhaust system allows for maximum heat exchange from the exhaust gas.
