    • A method and an apparatus for posttreatment of exhaust gases of internal combustion engines after an engine operation includes an intake system and an exhaust gas treatment system with an exhaust gas catalytic converter. Secondary air that originates in an air source can be delivered to the exhaust gas treatment system at a first secondary air inlet. After an engine operation, with the exhaust gas catalytic converter at operating temperature, the throttle device in the intake system is closed. After the engine operation, the engine is shut off in a phase relationship in which inlet/outlet valves of at least one combustion chamber of the engine are open. By means of the air source, an air flow is generated, which discharges at a further inlet point in the intake system of the engine and flows through or bathes the components in the direction of the exhaust gas catalytic converter at operating temperature in the exhaust gas treatment system.
    • 在发动机运转之后的内燃机废气后处理方法和装置包括具有排气催化转化器的进气系统和废气处理系统。 来自空气源的二次空气可以在第一二次空气入口处被输送到废气处理系统。 发动机运转后,排气催化转化器在工作温度下,进气系统中的节流装置关闭。 在发动机操作之后,发动机以相位关系切断,其中发动机的至少一个燃烧室的入口/出口阀打开。 通过空气源,产生空气流,其在发动机的进气系统中的另外的入口处排出,并且在排气中的操作温度下流过或沐浴部件在废气催化转化器的方向上 治疗系统。
