摘要： A method for controlling an engine having an intake manifold and an exhaust manifold, where an exhaust gas recirculation path with a valve is provided between said intake and exhaust manifold, and the engine has a turbocharger; the method comprising during at least one decreased engine output condition, increasing opening of the exhaust gas recirculation valve and adjusting exhaust expansion through a turbine of the turbocharger to decrease expansion through the turbocharger and thereby reduce a likelihood of turbocharger surge.

摘要： A method for operating an internal combustion engine Exhaust Gas Recirculation (EGR) system that includes producing an EGR valve position signal to decrease the amount of exhaust gas passed to the EGR cooler when a processor determines the EGR cooler efficiency is less than the predetermined level and producing an EGR coolant valve position signal to decrease the amount of coolant passed to the EGR cooler when such processor determines the EGR cooler efficiency is less than the predetermined level. The processor produced EGR valve and the EGR coolant valve position signals result in regeneration within the cooler, returning the effectiveness of the cooler to a near “clean” condition.
摘要翻译： 一种用于操作内燃机的方法当处理器确定EGR冷却器效率时，包括产生EGR阀位置信号以减少传递到EGR冷却器的废气量的废气再循环（EGR）系统小于预定水平，并且 产生EGR冷却剂阀位置信号，以减少当这种处理器确定EGR冷却器效率小于预定水平时传递到EGR冷却器的冷却剂的量。 处理器产生EGR阀，并且EGR冷却剂阀位置信号导致冷却器内的再生，将冷却器的有效性返回到接近“清洁”状态。
