A miller cycle engine according to the present disclosure includes: a variable valve operating device configured to continuously change the closing timing of an intake valve; a throttle valve arranged in an intake air passage; and a control device configured to execute an early closing miller cycle operation mode to control the variable valve operating device such that the intake valve closes at an intake bottom dead center or earlier. The control device is configured to: execute a late closing mode (e.g., decompression mode) to retard the closing timing relative to the intake bottom dead center at the time of engine start-up; and execute, where the pressure in the intake air passage has decreased to a first threshold value or lower first after the engine start-up, a mode switching processing to switch from the late closing mode to the early closing miller cycle operation mode.
