Internal combustion engine equipment equipped with direct injection gasoline engine and catalyst system

摘要

Stratified air supply ability the possession it does not do this invention, or, only barely the direct injection Otto engine which the possession is not done (12) with, the Otto engine (12) it is arranged in downstream, the catalyst system which 1 catalysts (18) it has at least (16) with the internal combustion engine which is included (10) it regards. Following to this invention, catalyst system (16), 0.8 engine capacity (VH) under or rated engine output (PNENN) per 100kW catalyst capacity under 1.3 (KV) it possesses, catalyst system (16) 1 catalysts (18) to the even precious metal ratio loading quantity is under 3.59g/dm3 at least, at least 1 catalysts (18) all the precious metal masses engine capacity (VH) per 1 liters are under 2g, or the Otto engine (12) rated engine output (PNENN) per 100kW are under 3.5g.
