内燃機関エンジンのための操作方法

摘要

In an operating method for a direct-injection gasoline internal combustion engine having a plurality of combustion chambers with at least partially low-NOx combustion (NAV) and a plurality of partial operating modes with at least one partial operating mode having controlled auto-ignition (RZV), a reduction in the reactivity of exhaust gas recirculated into the respective combustion chamber is achieved by means of an external exhaust gas recirculation using exhaust gas which has been conducted through an oxidation catalyst thereby improving the operating stability of the engine particularly in the auto-ignition partial operating mode.
