Catalytic reactor system - for internal combustion engine with start-up and main reactors

摘要

Internal combustion engine with a catalytic reactor for purifying the exhaust gases, which comprises a main catalytic reactor remote from the exhaust manifold and downstream of a starting catalytic reactor adjacent to the engine and able to be by-passed by a pipe with a closure element, partic. a temp.-controlled throttle butterfly or flap valve. Combines the good start-up properties of a catalytic reactor near the engine with the long life of a reactor under the car floor and remote from the engine.
