CONTROLLER FOR ENGINE AND METHOD FOR CONTROLLING ENGINE

The invention provides a controller for an engine and a method for controlling the engine. The controller for an engine includes processing circuitry configured to perform fuel cut-off for regenerating the filter by burning fine particulate matter collected in the filter. The processing circuitry is configured to perform an interruption process for interrupting the fuel cut-off in a case in whichwarming of the passenger compartment is requested when the fuel cut-off is being performed and an engine coolant temperature, which is a temperature of the engine coolant, becomes lower than or equalto a predetermined temperature after the fuel cut-off is started. 一种发动机的控制装置及发动机的控制方法，所述发动机的控制装置包括处理电路(processing circuitry)。处理电路构成为，实施用于使捕集器所捕集到的微粒子物质燃烧而使该捕集器再生的燃料切断。处理电路构成为，在燃料切断的实施期间，在要求了车室的供暖、且发动机冷却水的温度即发动机水温在燃料切断开始后降低到了预定的温度以下的情况下，进行中断该燃料切断的中断处理。
