摘要： A method of reducing icing-related engine misfires during operation of a vehicle is provided. The vehicle can include an engine and an engine control unit operable for at least partially controlling operation of the engine. The vehicle can further include a plurality of sensors in electrical communication with the engine control unit. The engine can include an air intake system and an exhaust system, wherein the air intake system can include a positive crankcase ventilation valve. The method includes predicting the presence of ice within the air intake system based upon an input to the engine control unit from at least one of the sensors.
摘要翻译： 提供一种在车辆操作期间减少与结冰有关的发动机失火的方法。 车辆可以包括发动机和可操作以至少部分地控制发动机的操作的发动机控制单元。 车辆还可以包括与发动机控制单元电连通的多个传感器。 发动机可以包括进气系统和排气系统，其中进气系统可以包括正曲轴箱通风阀。 该方法包括基于从至少一个传感器到发动机控制单元的输入来预测进气系统内的冰的存在。
