Method of controlling hydrocarbon accumulation in a particulate filter under certain operating conditions
摘要：
One embodiment of the invention includes a method of operating an internal combustion engine system comprising an engine, an oxidation catalyst, and a particulate filter, the method comprising: determining if the outlet temperature of exhaust gas from the oxidation catalyst is below a first temperature, measuring the time that the outlet temperature of exhaust gas from the oxidation catalyst is below the first temperature, determining if the measured time has exceeded a first time period, and if so, elevating the temperature of the exhaust gas exiting the oxidation catalyst.
摘要（中）：

本发明的一个实施例包括操作包括发动机，氧化催化剂和颗粒过滤器的内燃机系统的方法，所述方法包括：确定来自氧化催化剂的废气的出口温度是否低于第一温度， 测量来自氧化催化剂的废气的出口温度低于第一温度的时间，确定测量时间是否超过第一时间段，如果是，则升高离开氧化催化剂的废气的温度。
